| 摘 要： | 天敌真菌CN.7的二级培养基成份中,关键是C:N的比例:蔗糖:硝铵以30～40:1,菌丝生长最茂密。 盆栽试验指出:不施用CN.7菌制剂者,指示植物——蕃茄根系上的线虫瘿数为1152～1343个,平均1248个,每百克土壤中,含游离线虫为1050条;而施入CN.7菌制剂者,蕃茄根系上的线虫瘿数仅为15～334个,平均145个,每百克土壤中含游离线虫数为97～195条,平均137条,经过处理后线虫瘿及土壤中的游离线虫,都大幅度下降。 盆栽试验证明:CN.7菌株捕捉线虫的能力,可投入防治线虫的田间试验。

| Abstract: | The key elements among the elements of secondary medium for CN.7 nematode-destroying fungi are sugar and NH4NO3 and the best growth for haphae is the suitable ratio of 30-40 to 1 of two elements.Pot incubation test demonstrates: if not applying CN.7 nematode-destroying fungi, the number of nematode-galls on the roots of indicated plants is 1152-1343, average: 1248 and the number of free nematode per 100 g soil is 1050; But when applying CN.7 nematode-destroying fungi the number of nematode-galls on the roots of indicated plants is 15-334. average: 145, the number of free nematode per 100 g soil is 97-195, average: 137.Pot incubation test demonstrates that the power of captured nematodes of CN.7 nematode-destroying fuagi can be experimented in the field. |
