| 摘 要： | 在不同供水条件下，对河西绿州灌区６种多熟轮作方式进行了３年３区节水轮作体系的研究，结果表明，在一定范围内，轮作全周期总产量，水分生产效率随灌水量增多有增加的趋势，超过一定限度后，产量和ＷＵＥ增加不明显；综合轮作体系产量效益，水效益及对土壤肥力状况的改善等因素，认为本区实现节水高产高效的最佳多熟轮作方式为油菜／马铃薯→小麦／马铃薯→玉米／／大豆和小麦／甜菜→玉米／大豆→亚麻／马铃薯。

| Abstract: | During 3 years,six different multiple cropping rotation systems were studied at varying levels of water application in Hexi oasis irrigation area.The results showed that the total yield and WUE of rotation system increased with adding of water application in a restricted range.But over the range,the yield and WUE would not increase because of no more available water.After comprehensive analysing the yield,WUE and soil fertilizer status influenced by rotation,the order of oilseed/potatoes-spring wheat/oilseed-maize/soy bean-flax/potatoes is regarded as optimum multiple cropping rotation system for fulfilling water-saving,high yield and efficiency. |
