摘要
以18年生的"宁冠"和"新红星"苹果品种为试材,以大田漫灌为对照,研究了沟灌、交替灌溉2种不同灌溉方式对苹果树体生长、叶片生理及光合特性的影响,以期提高苹果水分利用效率、产量和品质。结果表明:交替控灌不但节约时间,并且显著的节省了水资源;在不影响营养生长的情况下,促进了叶绿素的形成,在提高光合速率的同时使蒸腾速率显著下降,最终显著提高了叶片水分利用效率。
Using 18-year-old‘Ningguan＇and‘Xinhongxing＇apple varieties as materials,with field irrigation as control,the effect of furrow irrigation,alternate irrigation of two different irrigation treatments on tree growth and leaf physiological and effect of photosynthetic characteristics were studied,in order to improve water use efficiency,yield and quality of apple.The results showed that,alternate control irrigation not only saved time,but also saved water resources.Under the condition of without affecting vegetative growth,it significantly contributed to the formation of chlorophyll,the increasing of photosynthetic rate at the same time made the transpiration rate dropped significantly,eventually improved the leaf water use efficiency significantly.
