不同栽培模式对大麦生育期间土壤水分及产量的影响

通过大田试验分析了全膜覆土穴播、垄作沟灌及平作条播栽培模式对大麦的土壤水分时空动态、产量及其水分利用效率的影响。结果表明,全膜穴播处理极有利于大麦的早期出苗及营养生长。但垄作沟灌栽培处理有利于促进大麦生殖生长。全膜穴播处理产量较垄作沟灌和平作条播处理分别增产10.9%和15.31%,并且WUE分别高10.69%和11.09%,说明全膜穴播栽培处理增加了大麦土壤的可利用水分,提高了产量和WUE。

Effects of differernt cultivation modes on soil moisture and yield during the barley growth period

Through the field experiments, analyzed the effects of three cultivation modes as film-mulched soil holes cultivation,ridge furrow and conventional strip drill on the dynamics change of soil moisture, yield and water use efficiency of barley. The results showed that the treatment of film-mulched soil holes cultivation was very useful to the barley early seedling and vegetative growth. But the ridge furrow irrigation cultivation was useful to promote the barley reproductive growth. The yield of film-mulched soil holes cultivation treatment was increased 10.9% and 15.31%, respectively, compared with the ridge furrow and conventional strip drill trseatment, also the WUE was heightened 10.69% and 11.09%, respectively. It explained that the soil moisture application can be increased by the film-mulched soil holes cultivation treatment and increased the yield and WUE.
