摘要: 通过膜下滴灌马铃薯在不同灌水量下,生长发育及产量形成的差异,从理论上探明膜下滴灌马铃薯水分吸收与产量形成的关系及调控机制,确定马铃薯节水与高产统一的灌溉制度。设0,1050,1350,1650,1950,2250m3/hm26个灌水处理。膜下滴灌条件下,随着灌水量的增加,马铃薯株高、茎粗、地上器官干质量、块茎产量都随着灌水量的增加呈现单峰曲线变化。适量增加马铃薯生育期的灌水量,有利于马铃薯植株生长和块茎形成与膨大,进而提高产量。适量灌水可促进马铃薯植株生长,并有利于延缓植株衰老,提高大薯率和块茎产量。该试验条件下,灌水量为1650m3/hm2时块茎产量最高,可做为生产中的适宜灌水量。

Abstract: Studing the differences of potato growth and yield formation under different irrigation quantity with drip irrigation, the relationship of potato moisture absorption and yield formation and regulatory mechanism were theoretically verified, to determine the potato irrigation system of water saving and high yield.With the increase of irrigation quantity, plant height, stem diameter, the dry weight of ground organs and tuber yield were unimodal curve change with drip irrigation under membrane. Yield was the highest when irrigation quantity was 1 650 m3/hm2, which was the most suitable irrigation quantity. A moderate amount of irrigation can promote the plant growth and was beneficial to delay the plant senescence.
