Root knot nematode prevention and control method in greenhouse crop planting

Abstract

The invention discloses a root knot nematode prevention and control method in greenhouse crop planting, the method comprises: after crops are harvested, greenhouse soil in the idle period is deeply ploughed to a preset depth, and the greenhouse soil is subjected to steaming and drying for a preset time; quicklime is scattered to the greenhouse soil for adjusting the pH value of the greenhouse soilto a target pH value; after the greenhouse soil is subjected to fine tillage, high-temperature hot water is used for spraying the greenhouse soil; the whole greenhouse is sealed at high temperature and subjected to high-temperature steaming and drying. The method provided by the invention has the advantages that according to the characteristic that root knot nematodes are sensitive to heat, a physical and chemical combination control method is adopted, namely by the technical means of improving the pH value of the soil through the quicklime and combining high-temperature hot water to disinfect and kill insects, the soil reaches a high temperature and is maintained at a high temperature state, and all root knot nematodes can be completely killed. The root knot nematode prevention and control method is simple to implement, low in cost, easy to popularize and apply and capable of improving the pH value of the soil, and is free of pollution to soil and harmless to human and livestock.

Description

technical field [0001] The invention relates to the field of crop disease and insect pest control, in particular to a root-knot nematode control method in greenhouse crop planting. Background technique [0002] Root-knot nematode is one of the more serious diseases that have occurred on vegetables in recent years, mainly harming more than 20 kinds of vegetables such as melons and fruits, solanaceous fruits, vegetables, and cabbage. With the expansion of vegetable cultivation area in protected greenhouses, the harm of root-knot nematodes has become a prominent problem in production, and its occurrence is on the rise, with yield losses reaching 30%-50%. Therefore, the prevention and control of root-knot nematode diseases of greenhouse vegetables has become particularly important. [0003] At present, in the cultivation of vegetable and fruit crops, due to the extensive use of chemical fertilizers, soil acidification has been caused, which stimulates the growth of root-knot ...

AI Technical Summary

Problems solved by technology

However, the current root-knot nematode control measures in greenhouse planting cannot effectively solve the problem of root-knot nematode, and the control effect is poor.
