机收稻田皮带辗压区紫云英生长恢复技术研究

Study on Growth Recovery Techniques of Rolling Belt Area in Milk Vetch after Rice Machine-Harvesting

于2012-2014年通过田间试验,研究了紫云英不同播种量与不同播期、水稻不同割茬高度和机收时土壤不同水分含量对皮带辗压区紫云英产量的影响。结果表明:适当增加紫云英播种量、推迟5d播种,水稻高茬(30cm)机收、机收时土壤低含水量(≤30%)和机收后稻草均匀覆盖均有利于增加皮带辗压区单位面积紫云英产量。

A field experiments between 2012-2014 were conducted to study the effects of different sowing rate and sowing date of milk vetch, stubble height of rice plant and different soil moisture on milk vetch yield of rolling belt area after rice machine-harvesting. The results showed that high milk vetch yield of rolling belt area could be obtained for summarizing in the condition on increasing appropriate sowing rate, delaying 5 days for sowing, harvesting with high stubble（30cm）, staying for low soil water content at ≤30% and implementing uniform straw mulching after rice machine-harvesting.
