| 摘 要： | 目的]研究鸡粪发酵提取液对番茄生长及根结线虫病防治效果的影响,为科学利用鸡粪防治作物根结线虫病提供参考.方法]设5、10、25、50、100、300、500和1000倍8个稀释倍数的鸡粪发酵提取液处理,以清水为对照,通过浇灌已接种南方根结线虫的盆栽番茄,研究其对番茄植株生长及根结线虫病防治效果的影响;通过室内培养2龄根结线虫和根结线虫卵,研究不同稀释倍数的鸡粪发酵提取液对根结线虫致死和根结线虫卵孵化的影响.结果]50、100和300倍鸡粪发酵稀释液更有利于番茄植株前期生长;5、10和25倍鸡粪发酵稀释液更有利于番茄植株后期生长,且能显著降低根结线虫发病率,最高防效达72.7%.培养试验结果表明,5、10和25倍鸡粪发酵稀释液能显著抑制根结线虫卵孵化,抑制率在70.0%以上;5和10倍鸡粪发酵稀释液对根结线虫的致死作用明显,处理后24 h即达到100.0%的致死效果.结论]5~10倍稀释的新型鸡粪发酵提取液能促进番茄植株生长,显著抑制根结线虫卵的孵化,杀死2龄线虫,减少根结线虫病的发生,是一种操作简便且环保安全的根结线虫病防治方法.

| Abstract: | Objective]The effects of chicken manure fermented extract on the tomato growth and control efficiency of root knot nematode were studied to provide reference for scientific use of chicken manure to control root knot nema-tode.Method]Eight diluted multiples(5,10,25,50,100,300,500 and 1000 times)of chicken manure fermented ex-tract were used. Clear water was taken as control. Their effects on growth of tomato plants and the control efficiency of root knot nematode were studied by irrigation of the potted tomatoes inoculated with root knot nematodes. The second in-star root knot nematode and root knot nematode eggs were cultured indoor to study the effects of different dilutions of chicken manure fermented extract on lethality of root knot nematode and hatching of its eggs.Result]The pot experiment results showed that 50,100 and 300 times of chicken manure fermented liquid could promote the growth of tomato plants at early stage. High concentration(diluted 5,10 and 25 times)of chicken manure fermented liquid could enhance the growth of plants at late stage and decrease incidence of root knot nematode with the highest control efficiency of 72.7%. The culture experiment results showed that high concentration(diluted 5,10 and 25 times)of chicken manure fermented diluent could significantly reduce the hatchability of root knot nematode eggs with inhibition rate of 70.0%. Above all,5 and 10 times dilution of chicken manure fermented extract caused obvious lethality to root knot nematodes,with a lethal effect of 100.0% 24 h after treatment.Conclusion]5-10 times of chicken manure fermented diluent can promote the growth of the tomato plant,plays an important role in inhibiting the hatching of the eggs and killing the second instar juve-nile and reduce the incidence of root knot nematode. It is a simple and safe method to prevent and control root knot nema-tode disease. |
