堆肥提取液和发酵液防治番茄根结线虫病的盆栽试验

Pot Experiment of Compost Extract and Fermentation Broth for the Prevention and Control of Tomato Root Knot Nematodes

以水稻秸秆、香蕉茎叶等为试材,采用盆栽试验,研究了不同堆肥的提取液和发酵液不同稀释倍数对番茄根结线虫的防治效果。结果表明:各堆肥提取液和发酵液对番茄根结线虫病都有一定的防治作用。其中平菇培养废料10倍提取液、茶麸5倍提取液和5倍发酵液的防效最好,根结线虫防效达74.19%。其次是水稻秸秆5倍提取液、香蕉茎叶10倍发酵液、玉米秸秆5倍发酵液,根结线虫防效分别为67.74%、66.67%、65.59%。在虫口减退率和虫口防效方面茶麸5倍提取液70d后的防效最好,虫口防效达86.05%。堆肥提取液和发酵液对植物株高的影响较大,但对茎围影响较小。

Taking rice straw,banana stems and leaves as the materials,the control effect of different extracts and fermentation broth dilution of different composts with pot experiment was studied.The results showed that different compost extract and fermentation broth all had a certain control effect on the tomato root-knot nematodes,among which the 10-fold mushroom cultivation waste extract,5-fold tea bran extract and 5-fold fermented broth had the best control effect（74.19%）.Then the control effects of 5-fold rice straw extract,10-fold fermented broth of banana stems and leaves and 5-fold fermented broth of corn stalk were in the second place,which were 67.74%,66.67% and 65.59%,respectively.5-fold tea ban extract after 70 days had the best control effect and the population reduce rate,with a population control effect of 86.05%.The compost extract and fermented broth had a greater effect on the height of the plants and less effect on the stalk width.
