| 1 | Effects of Application of Cassava Alcohol Anaerobic Fermentation Liquid and Mulching of Film on Overwintering and Next Year's Growth and Yield of Banana显示文摘The effects of application of cassava alcohol anaerobic fermentation liquid and mulching of film on overwintering and next year's growth and yield of banana were investigated in this study.The results showed that the application of cassava alcohol anaerobic fermentation liquid with COD concentration of 1 200-2 000 mg/L(900 m^3/hm^2) and mulching of film significantly increased the soil organic matter and available potassium contents in banana orchard,improved the cold resistance of banana seedlings,increased the pseudostem height,pseudostem circumference,green leaf number and chlorophyll content of next year's banana seedlings,brought the flower bud emergence period and harvest period forward,and significantly increased the yield per plant. | Yunchuan MO Yingyi DENG Xu ZHENG Yixin YE Ganhui MO Minzheng WEI Weiliu LI Feng LI Jiechun PAN Chanchan QIN Meiling SU Yao FU | 2016 | Agricultural Science & Technology2016，17，7： | 2 |
| 2 | Study on Effects of Organic Nutrient Solution on Amino Acid Contents in Litchi (Litchi chinensis Sonn.) Fruit显示文摘[Objectives] This study was conducted to investigate the effect of organic nutrient solution on litchi quality. [Methods] Different concentrations of organic nutrient solutions were sprayed on litchi leaves to study their effects on amino acid contents in the fruit of litchi cultivar 'Qinzhouhongli'. [Results] The results showed that the organic nutrient solution could significantly promote the growth of litchi fruit at various development stages and improve fruit quality by spraying the organic nutrient solution for 3 times with a dilution concentration of 500-1 500 times during fruit development(at an interval of 15 d) of litchi. It could increase the total essential amino acid, total semi-essential amino acid, lysine, phenylalanine, threonine, methionine, valine, leucine, histidine, arginine, aspartic acid, glycine, serine, proline, alanine and tyrosine contents. Spraying the organic nutrient solution with a dilution concentration of 1 000 times achieved the best effect of promoting the growth and improving quality of litchi fruit. [Conclusions] This study provides a theoretical basis for high-quality production and nutritional quality evaluation of litchi and the development of functional processed litchi products. | Yingyi DENG Chanchan QIN Hui WANG Xinwei CHEN Jiechun PAN Jiongzhi XU Jianan HE Guorui HU Xiao QU | 2019 | Agricultural Biotechnology2019，8，2： | 1 |
| 3 | A machine learning-assisted multifunctional tactile sensor for smart prosthetics显示文摘The absence of tactile perception limits the dexterity of a prosthetic hand and its acceptance by amputees.Recreating the sensing properties of the skin using a flexible tactile sensor could have profound implications for prosthetics,whereas existing tactile sensors often have limited functionality with cross-interference.In this study,we propose a machine-learning-assisted multifunctional tactile sensor for smart prosthetics,providing a human-like tactile sensing approach for amputations.This flexible sensor is based on a poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate)(PEDOT:PSS)-melamine sponge,which enables the detection of force and temperature with low cross-coupling owing to two separate sensing mechanisms:the open-circuit voltage of the sensor as a force-insensitive intrinsic variable to measure the absolute temperature and the resistance as a temperature-insensitive extrinsic variable to measure force.Furthermore,by analyzing the unsteady heat conduction and characterizing it using real-time thermal imaging,we demonstrated that the process of open-circuit voltage variation resulting from the unsteady heat conduction is closely correlated with the heatconducting capabilities of materials,which can be utilized to discriminate between substances.Assisted by the decision tree algorithm,the device is endowed with thermal conductivity sensing ability,which allows it to identify 10 types of substances with an accuracy of 94.7%.Furthermore,an individual wearing an advanced myoelectric prosthesis equipped with the above sensor can sense pressure,temperature,and recognize different materials.We demonstrated that our multifunctional tactile sensor provides a new strategy to help amputees feel force,temperature and identify the material of objects without the aid of vision. | Yue Li Lin Yang Shihao Deng Hong Huang Yingyi Wang Zuoping Xiong Simin Feng Shuqi Wang Tie Li Ting Zhang | 2023 | InfoMat2023，5，9： | 0 |
| 4 | Study on Infection Ability of Rhizobium radiobacter from Rosa chinensis to Peach Tree显示文摘[Objectives] This study was conducted to analyze the infection ability of Rhizobium radiobacter from Rosa chinensis to peach tree,so as to provide a theoretical basis for the identification and control of crown gall of peach. [Methods]With peach variety ' Chiyohime' as an experimental material,R. radiobacter GOU1 was extracted from crown gall tissue of R. chinensis susceptible to crown gall,and its infection ability to peach tree was studied by in-vitro dip method.[Results]Stem segments of peach tree were inoculated with R. radiobacter GOU1 by in-vitro dip method. Calli grew rapidly after inoculation,and 28 d later,the infection rate of R. radiobacter GOU1 was 50%,indicating that R. radiobacter GOU1 could infect peach tree easier. The infection on stem segments of peach tree could be detected in the fourth week by in-vitro dip method. Culturing peach stem segments in MS medium containing 10 μM/L NAA and 10 μM/L BAP in vitro is beneficial to survival and could promote growth of callus. [Conclusions]The detection rate of R. radiobacter GOU1 infection on stem segments of peach tree did not change from the fourth week to the sixth week. Therefore,in future studies,the detection of R. radiobacter infection on inoculated stem segments of peach tree could be performed after 4 weeks of culture rather than 6 weeks of culture. | Ganhui MO Yingyi DENG Hirokazu FUKUI | 2018 | Agricultural Biotechnology2018，7，3： | 0 |
