Rice filed and upland field rotation method for prevention and treatment of cucumber root-knot nematodes

Abstract

The invention discloses a rice filed and upland field rotation method for prevention and treatment of cucumber root-knot nematodes, which comprises the following steps: (1) performing field planting of cucumbers in October each year in a sunlight greenhouse or a vinyl house, carrying out production management by the book, and finishing harvest prior to May next year; (2) ploughing the soil after clearing up cucumber vines and a support frame of the cucumber vines, and irrigating the soil and performing field planting of aquatic vegetables with a growth period not exceeding six months; (3) during the whole growth period of the aquatic vegetables in the step (2), the soil moisture content is over 70%, avoiding irrigation in half a month prior to harvest; covering a sunshade net or a straw curtain on a film of the sunlight greenhouse or the vinyl house, and enabling temperature in the sunlight greenhouse or the vinyl house not to be higher than 30 DEG C; and (4) finishing harvest of the aquatic vegetables in the step (2) by the end of September in the current year, and performing field planting of the cucumbers after soil ploughing. The rice filed and upland field rotation method is adopted to carry out prevention and treatment of the root-knot nematodes, not only are environmental pollution and damage to human health which are caused by chemical pesticides for prevention and treatment of the root-knot nematodes avoided, but also planting costs do not need to be added, and the aim of thorough prevention and treatment can be achieved.

Description

technical field [0001] The invention relates to the control of diseases and insect pests in vegetable planting, in particular to the control method of root-knot nematode. Background technique [0002] At present, the planting area of ​​vegetables in protected areas in my country continues to expand. Because the temperature and humidity conditions in protected areas are suitable for the reproduction and growth of root-knot nematodes, coupled with the continuous planting of the same host crop or the continuous planting of the same type of crops, root-knot nematodes are caused. It gets worse year by year. Root-knot nematode is an important pathogen that harms vegetables such as cucumbers and tomatoes. This disease commonly occurs in various cucumber production areas and greenhouses in China. Generally, it can cause a 20% to 30% reduction in cucumber production, and in severe cases, it will never be harvested. With the continuous increase of the area of ​​vegetables in protected...
