1多温蓄冷车设计与车内温度场分析显示文摘为克服现有蓄冷车控温范围有限、不可多温共配等问题,设计了一款集车载制冷系统、独立蓄冷槽、隔热车厢(冷冻和冷藏单元)、导风槽、内隔板等于一体的多温蓄冷车。该多温蓄冷车将蓄冷槽安装在车厢前端并独立隔热保温。夜间利用低谷电对蓄冷槽内相变蓄冷材料进行充冷;当多温蓄冷运输时,冷冻单元通过车厢前端送风系统将冷能导出并调控,冷藏单元通过导风槽将冷气导入并调控。对车厢内冷冻冷藏单元体积比为1∶1,温度分别设定为-15. 0℃和3. 0℃工况进行了仿真和试验对比分析。研究表明,所构建的多温蓄冷车温度模拟值与试验值的均方根误差在0. 7~1. 1℃之间,总体偏差合理,可较好地反映多温蓄冷车内温度场分布状况。试验结果也表明,该多温蓄冷车车厢冷冻、冷藏单元可有效控温10 h以上,满足配送运输需要;平均温度分别在-14. 2~-12. 9℃和3. 4~4. 2℃间波动,波动范围分别为1. 3℃和0. 8℃,温度绝对不均匀度系数S在1. 2内,较传统蓄冷车平均温度波动值降低了73. 7%,S值降低了50%以上。改变车厢内冷冻冷藏单元体积比的进一步仿真也表明,蓄冷车内温度场分布仍然均匀,可满足实际运输需要。刘广海 吴俊章 FOSTER A 谢如鹤 唐海洋 屈睿瑰 2019农业机械学报2019,50,4:11
2Apple dwarfing rootstocks exhibit an imbalance in carbohydrate allocation and reduced cell growth and metabolism显示文摘Apple dwarfing rootstocks cause earlier shoot termination and reduced root and shoot mass.To identify physiological factors responsible for rootstock-induced growth restriction,we compared vascular-enriched gene expression between two dwarfing rootstocks(‘M27’and‘M9’)and the vigorous rootstock‘M793’using RNA sequencing and quantitative reverse transcriptase PCR.Differentially expressed genes common to both dwarfing rootstocks belonged to five main biological processes:(1)primary metabolism,(2)cell wall synthesis and modification,(3)secondary metabolism,(4)hormone signalling and response and(5)redox homeostasis.Genes promoting the biosynthesis of amino acids,lipids and cell walls were downregulated in dwarfing rootstocks,whereas genes promoting the breakdown of these compounds were upregulated.The only exception to this trend was the upregulation of starch synthesis genes in dwarfing rootstocks.Non-structural carbohydrate analysis demonstrated that starch concentrations in‘M9’roots,stems and grafted‘Royal Gala’(‘RG’)scions were double that of equivalent tissues from‘RG’homo-grafted trees(‘RG’/‘RG’).Fructose and glucose concentrations were much lower in all three tissues of the‘RG’/‘M9’trees.Together,these data indicate that dwarfing rootstocks are in a state of sugar depletion and reduced cellular activity despite having large starch reserves.Another significant finding was the over-accumulation of flavonoids and the downregulation of auxin influx transporters MdAUX1 and MdLAX2 in dwarfing rootstocks.We propose that both factors reduce polar auxin transport.The results of this study contribute novel information about the physiological state of dwarfing rootstocks.Toshi M Foster Peter A McAtee Chethi N Waite Helen L Boldingh Tony K McGhie 2017Horticulture Research2017,4,1:4
