摘要/Abstract

摘要： 11984～1986年从杭州市郊黄瓜、番茄、青椒,大白菜等健苗根表及根围土壤分离得1000多株菌株,从中筛选出8个拮抗细菌防治番茄苗期病害。1986～1987年在温州市扩大试验,种子细菌处理后,能抑制发瘸率,提高出苗率拈抗效果在60％以上,最高达100％;还能促进植株生长,提高单株产量。用化学农药甲霜灵与代森锌混配处理,得到同样防治效果。

Abstract: Eight antagonistic bacteria were isolated from the roots and surrounding soil of cucumber, tomato, eggplant, Chinese cabbage, and green pepper plants in the suburbs of Hangzhou. Field trials of seed treatment with the antagonistics to control two most important tomato diseases, Rhizoctonitt solani and Pythium sp., were conducted during 1986-1987 in Henzhou. A result of over 60% (max. 100%) suppression of the two diseases was obtained. The control effects were similar to that by using a chemical mixture of Metalaxyl and Zineb. Treatments with the antagonistics were also found to stimulate the seed germination and growth of tomato, and increased the yield.
