绥棱县地处黑龙江省第三四积温带,是全国大豆生产基地和出口基地,全县总耕地面积106万亩,由于自然条件决定,多年来,大豆种植面积一直稳定在40万亩,地下害虫和孢囊线虫的发生是困扰大豆生产、影响大豆产量的主要因素。种子包衣剂的使用有效地防治了地下害虫,控制了大豆孢囊线虫的发生,促进了幼苗生长,已为广大农户所接受。1990～1993年我们连续引进大豆种衣剂4号进行试验和多点次示范,收到了保苗增产的良好效果。1994～1995年两年从天津北方种
Sulei County is located in Heilongjiang Province, the third temperature zone, is the national soybean production base and export base, the county total area of 1.06 million mu of arable land, due to natural conditions, over the years, soybean acreage has been stable at 400000 acres, underground The occurrence of pests and cyst nematode is a major factor that plagued soybean production and affected the yield of soybean. The use of seed coating agent effectively control underground pests, control the occurrence of soybean cyst nematode and promote seedling growth, which has been accepted by the majority of farmers. From 1990 to 1993, we continuously introduced soybean seed coating agent No. 4 to carry out experiments and multi-point demonstration, and received the good effect of increasing seedling yield. From 1994 to 1995 two years from northern Tianjin species
