| 1 | Effects of narrow plant spacing on root distribution and physiological nitrogen use efficiency in summer maize显示文摘The objective of this study was to understand the effects of plant spacing on grain yield and root competition in summer maize(Zea mays L.). Maize cultivar Denghai 661 was planted in rectangular tanks(0.54 m × 0.27 m × 1.00 m) under 27 cm(normal) and 6 cm(narrow) plant spacing and treated with zero and 7.5 g nitrogen(N) per plant. Compared to normal plant spacing, narrow plant spacing generated less root biomass in the 0–20 cm zone under both N rates, slight reductions of dry root weight in the 20–40 cm and 40–70 cm zones at the mid-grain filling stage, and slight variation of dry root weights in the 70–100 cm zone during the whole growth period. Narrow plant spacing decreased root reductive activity in all root zones, especially at the grain-filling stage. Grain yield and above-ground biomass were 5.0% and 8.4% lower in the narrow plant spacing than with normal plant spacing, although narrow plant spacing significantly increased N harvest index and N use efficiency in both grain yield and biomass, and higher N translocation rates from vegetative organs. These results indicate that the reductive activity of maize roots in all soil layers and dry weights of shallow roots were significantly decreased under narrow plant spacing conditions, resulting in lower root biomass and yield reduction at maturity. Therefore, a moderately dense sowing is a basis for high yield in summer maize. | Wenshun Jiang Kongjun Wang Qiuping Wu Shuting Dong Peng Liu Jiwang Zhang | 2013 | The Crop Journal2013，1，1： | 13 |
| 2 | Soil physical properties and maize root growth under different tillage systems in the North China Plain显示文摘The standard cultivation system in the North China Plain is double cropping of winter wheat and summer maize. The main effects of this cultivation system on root development and yield are decreases in soil nutrient content and depth of the plow layer under either long-term no-tillage or rotary tillage before winter wheat sowing and no tillage before summer maize sowing. In this study, we investigated the combined effects of tillage practices before winter wheat and summer maize sowing on soil properties and root growth and distribution in summer maize. Zhengdan 958(ZD958) was used as experimental material, with three tillage treatments: rotary tillage before winter wheat sowing and no tillage before summer maize sowing(RTW + NTM), moldboard plowing before winter wheat sowing and no tillage before summer maize sowing(MPW + NTM), and moldboard plowing before winter wheat sowing and rotary tillage before summer maize sowing(MPW + RTM).Tillage practice showed a significant(P < 0.05) effect on grain yield of summer maize. Grain yields under MPW + RTM and MPW + NTM were 30.6% and 24.0% higher, respectively, than that under RTW + NTM. Soil bulk density and soil penetration resistance decreased among tillage systems in the order RTW + NTM > MPW + NTM > MPW + RTM. Soil bulk densities were 3.3% and 515% lower in MPW + NTM and MPW + RTM, respectively, than that in RTW + NTM, and soil penetration resistances were respectively 17.8% and 20.4% lower,across growth stages and soil depths. Root dry matter and root length density were highest under MPW + RTM, with the resulting increased root activity leading to a yield increase of summer maize. Thus the marked effects of moldboard plowing before winter-wheat sowing on root length density, soil penetration resistance, and soil bulk density may contribute to higher yield. | Baizhao Ren Xia Li Shuting Dong Peng Liu Bin Zhao Jiwang Zhang | 2018 | The Crop Journal2018，6，6： | 10 |

| 5 | Exogenous SA or 6-BA maintains photosynthetic activity in maize leaves under high temperature stress显示文摘With global warming, high-temperature(HT) stress has become a major abiotic stress for crops, in particular summer maize in China. Photosynthesis is sensitive to HT. Salicylic acid(SA) and 6-benzyladenine(6-BA) can improve the adaptation of plants to various biotic and abiotic stresses. However, their contribution to maintaining photosynthetic activity and alleviating photoinhibition in maize leaves under HT stress is still unclear. The effects of exogenous SA or 6-BA on growth, photosynthesis capacity, photosystem Ⅱ(PSII) activity, subcellular ultrastructure, antioxidant system, and plant hormones in maize leaves under HT stress were investigated. Under HT conditions, application of SA or 6-BA up-regulated gibberellin and zeatin content in leaves, increasing leaf area index(LAI). It also expanded the stomata by reducing abscisic acid and jasmonic acid content in leaves, cooling them and increasing CO2supply to photosynthesis. A higher net photosynthetic rate, combined with increased activity of the antioxidant system, alleviated oxidative stress in maize plants sprayed with SA or 6-BA, allowing them to maintain their chloroplast ultrastructure and PSII activity, in particular electron transfer from QAto QB. The increased LAI and net photosynthetic rate per unit leaf area also resulted in the accumulation of more biomass. | Yuting Li Xuetao Han Hao Ren Bin Zhao Jiwang Zhang Baizhao Ren Huiyuan Gao Peng Liu | 2023 | The Crop Journal2023，11，2： | 2 |
| 6 | How delaying post-silking senescence in lower leaves of maize plants increases carbon and nitrogen accumulation and grain yield显示文摘Planting maize at high densities leads to early leaf senescence,and the resulting reduction in the number of lower leaves affects the plant’s root function and lowers its grain yield.However,the nature of the process by which lower leaf senescence affects biomass accumulation and grain yield formation in maize is not clear.This study aimed to shed light on how these factors are related by investigating the effects of the plant growth regulator 6-benzyladenine(6-BA)on the senescence of lower leaves of maize plants.In two maize cultivars planted at densities of 67,500(low density,LD)and 90,000(high density,HD)plants ha^(-1),plants treated with 6-BA maintained a high green leaf area index(LAI)longer than control(CK)plants,enabling them to maintain a higher photosynthetic rate for a longer period of time and produce more biomass before reaching physiological maturity.Spraying the lower leaves of maize plants with a 6-BA solution increased the distribution of;C-photosynthates to their roots,lower leaves and bracts,a result that can be ascribed to a decreased retention of;C-photosynthates in the stem and grain.In both seasons of the experiment,maize plants treated with 6-BA accumulated more N in grain and maintained a higher N content in roots and leaves,especially in lower leaves,than CK.Increased C assimilation in the lower leaves may explain why N uptake in plants subjected to the 6-BA treatment exceeded that in CK plants and why both photosynthesis rate and dry matter accumulation were maintained throughout grain filling.Our results suggest that a suitable distribution of C and N in leaves post-silking may maintain plant root function,increase N use efficiency,maximize the duration of high LAI,and increase grain yield. | Rongfa Li Dandan Hu Hao Ren Qinglong Yang Shuting Dong Jiwang Zhang Bin Zhao Peng Liu | 2022 | The Crop Journal2022，10，3： | 2 |

| 8 | Surface coal mining impacts on land use change and ecological service value:a case study in Shengli coalfield,Inner Mongolia显示文摘Coal plays a crucial role in global economic development and remains the most common and widely distributed fossil fuel worldwide.As the world's largest developing country,China's mining and utilization of coal resources have contributed signifcantly to the country’s rapid economic growth.Inner Mongolia is an ecologically fragile arid and semi-arid area of China.The exploitation of opencast mining has seriously hindered the sustainable use of regional land and the residents'well-being.Using ENVI-based remote sensing images from 2000,2005,2010,2015,and 2020,this study employed a random forest algorithm to divide land utilization types into construction land,vegetation,cultivated land,bare land,and water areas and analyzed the characteristics of land use and ecosystem service value changes over the past 20 years.The results were as follows:(1)Construction land in the mining area changed minimally from 2000 to 2020;vegetation and water bodies showed a decreasing trend,whereas bare and cultivated lands showed an increasing trend.Bare land exhibited the largest change in area proportion and water bodies the smallest.(2)The total ecosystem service value of the mining area declined from 10.939 to 9.527 billion Yuan.Vegetation ecosystem service value was the highest,followed by cultivated land and water,with the bare land ecosystem service value the lowest.(3)On a spatial scale,the total ecosystem service value of the Shengli mining area decreased year by year,indicating that land use changes in the mining area do have an impact on ecosystem service value. | Lijia Zhang Xu Zhou Yan Zhou Ji Zhou Jiwang Guo Zihan Zhai Yan Chen Xiangyan Su Lingxiao Ying Liwei Wang Ying Qiao | 2022 | International Journal of Coal Science & Technology2022，9，5： | 1 |
| 9 | Poor development of spike differentiation triggered by lower photosynthesis and carbon partitioning reduces summer maize yield after waterlogging显示文摘Stable yield of staple grains must be ensured to satisfy food demands for daily dietary energy requirements against the backdrop of global climate change. Summer maize, a staple crop, suffers severe yield losses due to extreme rainfall events, threatening food security. A randomized block experiment with four treatments: control, no water stress(CK);waterlogging for 6 days at the third leaf, sixth leaf stage,and 10 th day after tasseling, was conducted to investigate the mechanism of waterlogging-induced yield losses of summer maize. Waterlogging delayed plant growth and impaired tassel and ear differentiation,leading to high grain yield losses of Denghai 605(DH605). Waterlogging at third leaf(V3) stage reduced the photosynthesis of DH605, reducing total dry matter weight. Waterlogging at V3 stage reduced sucrose-cleaving enzymes activities in spike nodes and ears, reducing the carbon partitioned to ears(–53.1%), shanks(–46.5%), and ear nodes(–71.5%) but increasing the carbon partitioned to ear leaves(9.6%) and tassels(43.9%) in comparison with CK. The reductions in total carbon assimilate together with the reduced carbon partitioning to ears resulted in poor development of spikes(with respectively 15.2%and 20.6% reductions in total florets and fertilized florets) and lengthened the anthesis–silking interval by around 1 day, leading to high yield losses. | Juan Hu Baizhao Ren Shuting Dong Peng Liu Bin Zhao Jiwang Zhang | 2022 | The Crop Journal2022，10，2： | 1 |
| 10 | Differences in Carbon Nutrition between On-season and Off-season Longan during the Flowering Process显示文摘Flower-bud differentiation is the most critical stage of fruit yield formation,as well as a complicated carbon transfer process. To understand the changes of carbon during the flower bud differentiation process of longan,it is very important to adopt suitable planting measures and control flowering time. This study focused on the changes of sugar and starch content of on-season and off-season longan during the flowering process. The results showed that the accumulation and transformation of carbon differed between on-season and off-season longan during flower-bud differentiation process; to be specific,sugar and starch content in tissues differentiated from apical buds of on-season longan were reduced at the late flower-bud physiological differentiation stage except in leaf buds; on the contrary,sugar and starch content in off-season longan increased at the late flower-bud physiological differentiation stage: specifically,total sugar content increased from15. 43(- 7 d) to 31. 38 mg /g( 7 d); starch content increased from 5. 42 to 8. 31 mg /g during this time,which may be relevant to the external environment or tree original metabolism damaged by potassium chlorate. | Ziqin YANG Xingxing CHEN Jiwang HONG Lei ZHANG Jianbin LUO Songgang LI | 2014 | Agricultural Biotechnology2014，3，2： | 1 |

| 13 | Combined effects of high temperature and waterlogging on yield and stem development of summer maize显示文摘The purpose of this study was to identify the physiological mechanism underlying the effects of high temperature and waterlogging on summer maize.The stem development and yield of the maize hybrid Denghai 605 in response to high-temperature stress,waterlogging stress,and their combination applied for six days at the third-leaf,sixth-leaf,and tasseling stages were recorded.The combined stresses reduced lignin biosynthetic enzyme activity and lignin accumulation,leading to abnormal stem development.Reduction of the area and number of vascular bundles in stems led to reduced dry matter accumulation and allocation.Decreased grain dry weight at all three stages reduced grain yield relative to a control.In summary,high temperature,waterlogging,and their combined stress impaired stem development and grain yield of summer maize.The combined stresses were more damaging than either stress alone. | Jingyi Shao Peng Liu Bin Zhao Jiwang Zhang Xiangyu Zhao Baizhao Ren | 2023 | The Crop Journal2023，11，2： | 1 |
| 14 | Analysis of Carbon Content in Off-season Flowering and Non-flowering Longan Trees显示文摘After flower induction,some longan trees can successfully blossom and bear fruit,while others with similar tree body status can only sprout leaf buds.In order to investigate the main reason for these differences,in this study,off-season flowering and non-flowering longan trees were used as experimental materials to analyze the changes of carbon content in mature leaves,tender leaves,mature shoots,tender shoots and terminal buds of longan trees after flower induction by potassium chlorate. The result showed that carbon content played an important role in flowering process. Off-season longan trees with carbon content in mature leaves reached 50. 93 mg /g could successfully blossom,but those with carbon content in mature leaves lower than 37. 40 mg /g were usually difficult to blossom. In addition,the maturity of tender leaves posed great influence on flowering. Specifically,tender leaves with a higher maturity contained higher carbon content and could easily blossom,which could be used as a new indicator to evaluate flower induction in off-season longan trees. | Ziqin YANG Xingxing CHEN Lei ZHANG Jiwang HONG Songgang LI | 2014 | Agricultural Biotechnology2014，3，4： | 1 |

| 18 | Effects of H_2O_2 and NO on Flower Development and AP1 Gene Expression of Off-season Longan显示文摘[Objective] T his study aimed to investigate the effects of H_2O_2 and NO on flower development and AP1 gene expression of off-season longan. [Method] N ine-year-old off-season Chuliang longan was sprayed with enhancers and blockers of H_2O_2 and NO to analyze dynamic changes of flower development and AP1 expression. [Result] T he expression level of AP1 gene in off-season longan was improved during flower development. SNP and MV treatments up-regulated the expression level of AP1 gene in leaves and terminal buds to varying degrees during lateral primordium formation. Especially,SNP treatment exhibited the most remarkable effect. DMTU treatment significantly inhibited the expression of AP1 gene in leaves and terminal buds during lateral primordium formation. L-NNA treatment slightly inhibited the expression of AP1 gene in leaves and exerted no significant effect on expression of AP1 gene in terminal buds. [Conclusion]It can be speculated that the enhancement of NO and H_2O_2 signals is conducive to flower development of off-season longan,while blocking H_2O_2 signals may inhibit flower development of off-season longan. | Songgang LI Xinjun ZHANG Lei ZHANG Jiwang HONG Yeyuan CHEN | 2016 | Agricultural Biotechnology2016，5，4： | 0 |
| 19 | Responses of photosynthetic characteristics and leaf senescence in summer maize to simultaneous stresses of waterlogging and shading显示文摘A field experiment was performed to investigate the physiological mechanism of the simultaneous stresses of waterlogging and shading on leaf photosynthetic and senescence during three growth stages of summer maize.The responses of leaf gas exchange parameters and antioxidant enzyme activities of the summer maize hybrids Denghai 605(DH605)to waterlogging(W),shading(S),and their combination(W+S)for 6 days at the third leaf stage(V3),the sixth leaf stage(V6),and the tasseling stage(VT)were recorded.Shading,waterlogging,and their combination disturbed the activities of protective enzymes and increased the contents of H2O2and O-2,accelerating leaf senescence and disordering photosynthetic characteristics.Under waterlogging,shading and their combination,leaf Pn,the photo-assimilates and grain yield was decreased.The greatest reduction for waterlogging and the combined stresses occurred at V3 and that for shading stress occurred at VT.The individual and combined stresses reduced the activities of protective enzymes and inhibited photosynthesis,reducing the accumulation of photosynthetic compounds and thereby yield.Waterlogging and the combined stresses at the V3 stage showed the greatest effect on leaf photosynthetic and senescence,followed by the V6 and VT stages.The greatest effect for shading stress occurred at VT,followed by the V6 and V3 stages,and the combined influence of shading and waterlogging was greater than that of either single stress. | Baizhao Ren Weizhen Yu Peng Liu Bin Zhao Jiwang Zhang | 2023 | The Crop Journal2023，11，1： | 0 |
| 20 | A theoretical and deep learning hybrid model for predicting surface roughness of diamond-turned polycrystalline materials显示文摘Polycrystalline materials are extensively employed in industry.Its surface roughness significantly affects the working performance.Material defects,particularly grain boundaries,have a great impact on the achieved surface roughness of polycrystalline materials.However,it is difficult to establish a purely theoretical model for surface roughness with consideration of the grain boundary effect using conventional analytical methods.In this work,a theoretical and deep learning hybrid model for predicting the surface roughness of diamond-turned polycrystalline materials is proposed.The kinematic–dynamic roughness component in relation to the tool profile duplication effect,work material plastic side flow,relative vibration between the diamond tool and workpiece,etc,is theoretically calculated.The material-defect roughness component is modeled with a cascade forward neural network.In the neural network,the ratio of maximum undeformed chip thickness to cutting edge radius RT S,work material properties(misorientation angle θ_(g) and grain size d_(g)),and spindle rotation speed n s are configured as input variables.The material-defect roughness component is set as the output variable.To validate the developed model,polycrystalline copper with a gradient distribution of grains prepared by friction stir processing is machined with various processing parameters and different diamond tools.Compared with the previously developed model,obvious improvement in the prediction accuracy is observed with this hybrid prediction model.Based on this model,the influences of different factors on the surface roughness of polycrystalline materials are discussed.The influencing mechanism of the misorientation angle and grain size is quantitatively analyzed.Two fracture modes,including transcrystalline and intercrystalline fractures at different RTS values,are observed.Meanwhile,optimal processing parameters are obtained with a simulated annealing algorithm.Cutting experiments are performed with the optimal parameters,and a flat surface finish with Sa 1.314 nm is finally achieved.The developed model and corresponding new findings in this work are beneficial for accurately predicting the surface roughness of polycrystalline materials and understanding the impacting mechanism of material defects in diamond turning. | Chunlei He Jiwang Yan Shuqi Wang Shuo Zhang Guang Chen Chengzu Ren | 2023 | International Journal of Extreme Manufacturing2023，5，3： | 0 |
