摘要
生物制剂“防疫Ｉ号”由有机添加物与拮抗菌配制组成。将其与土壤按１∶２００比例混合后施入田间，防治青椒疫病的效果明显，田间防效为８１％。该制剂中的有机添加物可作为拮抗菌的营养源，从而使其在土壤中的数量增加，并能延续繁殖时间二个月以上。该制剂有促进青椒植株生长健壮的作用。
The biological-'Fangyi-I' is a combination of organic matter with antagonistic microorganisms. In our field test, soil was mixed with 'Fangyi-I' at a rate of 200:1 for field application. The results of field test showed that 'Fangyi-I' had an obvious effect of controlling capsicum phytophthora blight, the control effect was 81%. An amendment with organic matter(soyabean leaf tissues et al. )mixed at a rate of 0. 5 % in natural soil increased significantly the populations of antagonistic microorganisms, as compared to the unamended control. The population of antagonists tended to decrease only 2 months and more after soil application regardless of soil amendment with organic matter. 'Fangyi-I'showed also a promoting effect on the growth of capsicum.
