摘 要：
利用裂区设计方法，从生物学产量、小麦耗水规律及水分利用率方面对旱区小麦夏闲期的利用进行了探讨，论证了旱区小麦夏闲期利用的可能性。试验结果表明：小麦夏闲期种植玉米、子粒苋等作物既可于夏用期生产较多的干物质，对全年生物产量也有显著的增益作用。这种模式对于加强旱区小麦生产系统的生物循环，增强该系统在资源、生产及经济方面的可持续性都有重要的现实意义。试验结果还进一步说明这种模式对保证旱区麦农的短期利益，即保证小麦生产的稳定性，也无统计学上的显著影响。

摘 要：
Utilization of summer-fallow period in rain fed wheat growing area was studied byusing split plot experiment design in respect to biomass, wheat grain yield, water consumptionand water use efficiency. The feasibility of utilization of summer-fallow period in rainfed wheatgrowing area without significant loss of wheat grain yield was confirmed. The results showedthat growing forage crops such as corn and grain amaranth can result in significant increase ofbiomass in the summer-fallow period and in the whole year, which favours biomass recyclingand enhancement of sustainability of wheat production system in rain fed wheat growing area.
