“种子包衣”是根据不同作物的需肥特点及不同土壤的供肥能力,选用适宜配方,以兼有适度水稳性与水溶性的粘合剂粘附于种子表面,同时具有增产、防病、防虫的复合拌种效果。采用种子包衣新技术,可以减少田间防虫防病劳作,直接有效地增加作物产量。早在60年代,国外就已开始采用包衣技术,目前已在甜菜、瓜类、蔬菜、玉米等播种量少的作物上大面积应用。在我国,种子包衣技术的研究始于70年代初,但发展较慢,多年来一直停留在试验和小面积示范上。据1985年报道,北农大成功地采用芽孢杆菌粉、肥料及杀 “Seed coating” is based on the needs of different crops and fertilizer for different soil fertility, use the appropriate formula, with moderate water stability and water-soluble adhesive adhesion to the surface of the seed, while increasing production, anti- Disease, pest control compound seed dressing effect. The use of seed coating technology, can reduce field pest control disease prevention work, directly and effectively increase crop yield. As early as the 1960s, foreign countries started to use coating technology and have applied large-area crops such as sugar beets, melons, vegetables and corn with less seeding rate. In our country, the study of seed coating technology began in the early 1970s, but its development was slow. For many years, it has been staying on experimental and small-area demonstration. According to reports in 1985, BeiNongDa successfully used Bacillus powder, fertilizer and kill
