摘要
研究结果表明，辅以拮抗微生物的有机添加物“Ｍｘ”（主要成分为蚕豆粉、无机盐类等）对蔬菜土传病原菌的生物防治作用，不但能有效控制甜椒疫病菌（Ｐｈｙｔｏｐｈｔｈｏｒａｃａｐｓｉｃｉ）、立枯丝核菌（Ｒｈｉｚｏｃｔｏｎｉａｓｏｌａｎｉ）和终极腐霉（Ｐｙｔｈｉｕｍｕｌｔｉｍｕｍ）的侵染（防治效果分别达到８１％、８２％和７０％）；还可促进寄主植物的生长。实验同时证明，单一施用“Ｍｘ”亦具一定的防治作用。本文还就有机添加物“Ｍｘ”对这些病原菌的作用机理作了初步探讨。
The results of this study showed that organic amendment 'Mx', a mixture of nroadbean meal and inorganic matter et al., coated with antagonistic microorganisms gave good control effect on pepper blight disease (Phytophthora capsici) and tomato damping-off disease caused by Rhizoctonia solani and Pythium ultimum. The control effects were 81%,82% and 70%, respectively. The single use of 'Mx' not only was effective to a certain extent in controlling these diseases, but also had a function of stimulating host plant growth.The action mechanism of organic amendments 'Mx' involved in soil against these soil borne pathogens was also discussed preliminarily.
