为给旱地夏闲期管理提供参考依据,采用大田试验,研究了夏闲期施肥与覆盖处理对旱地冬小麦土壤储水量、产量及水分利用效率的影响。结果表明,夏闲期施肥可明显提高播前0～100、100～200厘米土层储水量,增加了冬小麦穗数、子粒产
In order to provide a reference for the management of dry land in summer and winter, field experiments were conducted to study the effects of summer and fallow fertilization and cover treatments on soil water storage, yield and water use efficiency of dryland winter wheat. The results showed that fertilizer application in summer and early summer significantly increased the water storage capacity of 0-100, 100-200 cm soil layers before sowing, increased winter wheat spike number, grain yield
