Tomato root-knot nematode biological trapping control method

Abstract

The invention discloses a tomato root-knot nematode biological trapping control method. According to the invention, with a reasonably set planting mode, a main crop is intercropped with a biological trapping plant. With an organic combination of the intercropping method and a plurality of technical measures, tomato root-knot nematode can be effectively controlled without using any chemical pesticides. With the method, tomato yield can be increased. The method accords with green and low-carbon concepts. With the method, a tomato root-knot nematode control effect can reach 87.8-91.4%, and tomato yield can be improved by 17.5% than that of a traditional control method.

Description

technical field

[0001] The invention relates to a method for controlling tomato root-knot nematode based on biological trapping, belongs to the technical field of green control of vegetable root-knot nematode, and is suitable for tomato hanging vine cultivation in solar greenhouses. Background technique

[0002] Root-knot nematode damage is one of the main hazards in the production process of tomato crops, which can cause more than 30% reduction in tomato production, or even no harvest. In recent years, the planting area of ​​vegetables in protected areas such as solar greenhouses in my country has continued to expand, and the temperature and humidity of the sun are suitable, coupled with continuous cropping all year round, resulting in the increase of root-knot nematodes year by year. The commonly used control method is basically the application of chemical pesticides, such as: thiazolphos, phoxim, damaron, dichloropromethazine, metabam and sulfuryl fluoride, etc., but a la...
