玫瑰黄链霉菌菌糠发酵物对蔬菜根结线虫病的防治

Control of Fermentation of Streptomyces roseoflavus Based on Mushroom Bran against Vegetable Root Knot Nematode Disease

针对玫瑰黄链霉菌Men-myco-93-63菌糠发酵物的生防效果进行研究和评价。通过温室黄瓜盆栽试验和京郊西瓜、豇豆的田间试验,检测该生防菌发酵物对蔬菜根结线虫病的防治效果及对植株促生效果和对果实品质的影响。结果表明:温室药效试验中,玫瑰黄链霉菌发酵物对黄瓜根结线虫病的防治效果为29.41%;田间药效试验中,玫瑰黄链霉菌发酵物对西瓜根结线虫病的防治效果为14.29%;对豇豆根结线虫病的防治效果为14.81%。田间施用玫瑰黄链霉菌菌糠发酵物后,对西瓜植株有明显的促生作用,一茬瓜在单果重方面与对照差异显著,且比对照提高18.03%,豇豆产量比对照增产10.20%。本文为玫瑰黄链霉菌Men-myco-93-63微生物菌肥的研发和应用提供参考依据。

In this paper,the biological control effect of fermentation of Streptomyces roseoflavus Men-myco-93-63based on mushroom bran was studied and evaluated.The controlling effects of fermentation of biocontrol bacteria on vegetable root knot nematode and its effects on promoting effect and fruit quality of plants were evaluated in the pot experiment of cucumber in greenhouse and field test of watermelon and cowpea in Beijing suburb field.The results showed that in the greenhouse efficacy test,the control effect of Streptomyces roseoflavus fermentation on cucumber root knot nematode disease was 29.41%.In the field efficacy test,the control effect of Streptomyces roseoflavus fermentation on watermelon root-knot nematode disease was 14.29%,and that of cowpea root-knot nematode disease was 14.81%.After the application of Streptomyces roseoflavus mushroom bran fermentation in the field,the growth of watermelon plants was obviously promoted.The single fruit weight of melon was significantly different from that of the control,and the yield of cowpea was increased by 18.03%and 10.20%compared with the control.This paper provides an important reference basis for the research and application of Streptomyces roseoflavus Men-myco-93-63microbial fertilizer.
