蚯蚓粪及浸提液对番茄根结线虫的防治效果
Evaluation of Control Effect of Vermicompost and Its Extracts on Tomato Root-knot Nematode
摘要
Abstract
The control effects ofvermicompost and its extracts on Meloidogyne incognita were investigated through laboratory assasys and pot experiments.The results indicated that egg hatching was significantly inhibited with increasing the extract concentration,and at the concentration of 90%,the relative inhibition rate was 71.63% and the hatchability rate was 11.88%,respectively.The knockdown rate and mortality of M.incognita were significantly increased with the increasing extract concentrations and treatment time.Compared with the control,the mortality rate was up to 88.46% at the concentration of 90%.Pot experiments showed that the number of root-knot was reduced and the relative control effects were significantly improved.When the dosage of vermicompost was 75%,the control efficacy could reach 70%,but the height was only 47.33 cm and the fresh weight of aerial part was 84.15 g.However,at the vermicompost dosage of 25%,the control efficacy was 36.3%,but the height is 61.33 cm and the fresh weight of aerial part was 84.15 g,which was the best treatment for the plant growth.关键词
