全膜双垄沟播玉米秸秆膜下带状还田模式对土壤水分和玉米产量的影响
Effcts of Whole Film Double Furrow Sowing Maize Straw Returning Pattern on Soil Moisture and Maize Yield
摘要
Abstract
[Objective]To study effcts of whole film double furrow sowing maize straw returning pattern on soil moisture and maize yield[Meth-od]Six treatments were designed to study effects of whole film double furrow sowing maize straw returning on maize agronomic characters,maize yield and soil water use efficiency.[Result]The agronomic characters,biological yield and water use efficiency of maize after the surface being covered by 2 cm were significantly lower than that of the whole film.Maize agronomic traits especially plant height,stem diameter decreased under maize straw returning returning patter.Grain yield decreased by 0.40%-7.42%,but the difference was not significant.The biological yield de-creased significantly,but the difference of economic coefficient was not significant.There was no significant effect of whole film double furrow so-wing maize straw returning on the long-term water consumption and soil water use efficiency.[Conclusion]The study provides theoretical basis for the application of the whole film double furrow seeding technique in the field of straw mulching.关键词
