不同栽培模式对大麦生育期间土壤水分及产量的影响

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

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。

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 efficien-cy of barley .The results showed that the treatment of film-mulched soil holes cultivation was very useful to the barley ear-ly 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 .
