研究了大豆专用复合药肥在大豆重茬地上应用后，对大豆产量的影响。试验证明，大豆专用复合药肥对大豆有明显的增产增收效果，增产２１０～８４０ｋｇ／ｈｍ２，增收６９３～２４７５元。其根本原因是大豆专用复合药肥既含Ｎ、Ｐ、Ｋ、微量元素，又含有杀虫剂、杀菌剂，能有效地防治大豆根腐病、根蛆病、孢囊线虫病，尤其对大豆重茬种植增产增收打下了良好基础。 The effect of special soybean compound fertilizer on soybean yield was studied. Experiments show that soy-specific compound fertilizer on soybean production increased significantly, yield 210 ~ 840kg / hm2, an increase of 693 ~ 2475 yuan. The fundamental reason is that the soybean compound fertilizer contains N, P, K and trace elements as well as insecticides and bactericides to effectively control soybean root rot, root myiasis and cyst nematode disease, especially soybeans Cropping crop yield increase laid a good foundation.
