【摘要】 研究了秸秆与地膜二元覆盖栽培对小麦田间生态环境及产量的影响。结果表明:秸秆与地膜二元覆盖麦田土壤变温幅度小,水分散失少;养分积累增加,有效分蘖多,后期叶面积大,干物质积累增加;有效穗多,穗大粒多,增产效果显著。籽粒产量较地膜覆盖、秸秆覆盖、露地栽培分别增产20.97%,10.29%,30.9%。更多还原

【Abstract】 The effect of straw and plastic film dual mulch on the ecological environment in the farmland and the yield of wheat planting was studied.Results showed that by using straw and plastic film dual mulch of wheat planting,both of the range of temperature difference and the loss of water in field of wheat were decreased;the soil nutrient contents were increased,the effective tillers of wheat plant were increased,later,the growth of leaves area and drymatter stage were advanced, the filling stage was extended,the grain yield of wheat increased obviously.The increasing in grain yield was about 20.97%,10.29%,30.9% respectively as compared with the plastic film mulch,the straw mulch and the unmulched cultivation. 更多还原
