摘　　要：为解决大豆播种后遇雨出苗不齐或者不出苗导致大豆产量降低的问题,以豆丰10号为材料,分别设置稻草(草苫)覆盖(T1处理)、单层遮阳网覆盖(T2处理)、双层遮阳网覆盖(T3处理)、地膜覆盖(T4处理)和无覆盖(CK)5个处理进行对比试验。结果表明,采取覆盖措施的处理均提升了大豆的出苗率,增幅59.00%~107.69%,极显著增加了大豆的出苗密度,提高了大豆的产量。双层遮阳网覆盖(T3)处理投入成本最高,地膜覆盖(T4)处理次之。双层遮阳网覆盖(T3)处理的投入产出比最高,达到了1.00∶4.41,单层遮阳网覆盖(T2)处理次之,地膜覆盖(T4)处理最低,仅有1.00∶2.41。综合来看,暴雨条件下,双层遮阳网覆盖(T3)处理增加了大豆的出苗密度,提高了大豆的产量,获得了最佳的投入产出比,在生产中可进行大面积推广。In order to solve the problem of soybean yield reduction caused by uneven emergence or non-emergence of soybean in rain,comparative test was carried out based on five treatments of straw mulching(T1),a layer of shading-net mulching(T2),two layers of shading-net mulching(T3),film mulching(T4),open filed(CK).Results showed that the coverage measures increased the emergence rate of soybean by 59.00%-107.69%,improved yield of soybean.T3 treatment had the highest input cost,followed by T4 treatment.T3 treatment had the highest input-output ratio,reaching 1.00∶4.41,followed by T2 treatment.And T4 treatment was the lowest,only 1.00∶2.41.In general,T3 treatment enhanced the seedling density of soybean under under rainstorm condition,obtained the optimal input-output ratio,and could be widely used in production.
