本文通过对峙培养,菌间交互作用机制观察及拮抗菌培养液对病菌生长影响的测定,探讨绿色木霉菌对番茄灰霉病菌的拮抗作用及其作用机制。室内及田间试验表明,绿色木霉·烯酰吗啉水分散片剂300～600倍液,对番茄灰霉病的防效为83/～95/,且对作物安全;其对病原菌的抑制作用是通过代谢产物(酶或有毒物质)的作用表现出来的。
In this paper, confrontation culture, the interaction mechanism between bacteria and antagonistic bacteria culture medium on the growth of bacteria to determine the antagonistic role of Trichoderma viride against Botrytis cinerea and its mechanism of action. The indoor and field experiments showed that the control effect of Trichoderma viride dimethomol water dispersible tablets 300 ~ 600 times on tomato gray mold was 83 / ~ 95 /, and it was safe to crops and its inhibitory effect on pathogenic bacteria It is manifested by the action of metabolites (enzymes or toxic substances).
