在大豆种植中,要注意与禾本科农作物进行至少3年的轮作种植,最大限度的避免重茬或迎茬种植的发生。但是在某些特殊情况,不能避免重、迎茬种植时,就要采取相应的具体措施来降低因重迎茬而带来的减产和农产品品质下降程度。一般情况下,可以从改善大豆生长环境、增加养分、选择优良品种以及加强虫害防治管理等方面着手,全面的提高栽培技术,从而最大程度的减少因重、迎茬带来的经济损失。1重、迎茬对大豆产量和品质的影响 In soybean planting, attention should be paid to the crop rotation with gramineous crops for at least 3 years, so as to avoid cropping or growing crops to the maximum extent. However, in some special cases, we can not avoid heavy planting and planting, we must take corresponding and specific measures to reduce the reduction of crop yield and the decline in the quality of agricultural products. Under normal circumstances, from the improvement of soybean growth environment, increase nutrients, select the best varieties and strengthen pest control management, comprehensively improve the cultivation techniques, thus minimizing the heavy, Yingjiu bring economic losses. 1 heavy, Ying-stubble on soybean yield and quality
