黑龙江省是我国大豆主产区,也是大豆种衣剂的使用大省,大豆种子包衣是我省农户有效防治大豆苗期病虫害,做到一次播种保全苗,保证大豆稳产高产的主要措施之一。我省大豆种衣剂市场销量大体经历了3个阶段,2000年以前,用量为上升阶段,其中2000年用量接近2 500t,2000～2004年处于用量稳定阶段,各年基本持平;2005～2006年为用量逐年下降阶段,其中2006年用量在1 500t左右,2007年进一步下降。近年来,我省大豆种植面积一直保持在333万hm~2左右,播种面积的调整对大豆种衣剂用量下降影响不大。
Heilongjiang Province is the main producing area of soybean in China. It is also a major province in which soybean seed coating is used. Soybean seed coating is one of the main measures for farmers in our province to effectively control pests and diseases of soybean at the seedling stage so as to ensure a stable and high yield of soybean . The sales volume of soybean seed coating in our province has generally gone through three stages. Before 2000, the dosage was in the rising stage, of which the dosage was close to 2 500 tons in 2000 and the dosage was stable in 2000-2004, basically the same in each year. From 2005 to 2006 For the amount of declining stage, of which in 2006 the amount of 1,500 t in 2007, further decline. In recent years, soybean planting area in our province has been maintained at about 3.33 million hm ~ 2, the sown area of the adjustment of the amount of soybean seed coating decreased little.
