Facilities vegetable farm nematocide and its use method

Abstract

The invention relates to a soil disinfector, in particular to a facility vegetable field eelworm killing agent and an application method thereof to solve the problem of preventing and controlling the root knot nematode. The eelworm killing agent comprises the components in weight percentage: 10 to 20 percent of calcium cyanamide and 80 to 90 percent of organic material. The calcium cyanamide and the organic material are mixed and stirred evenly and mechanically to prepare the eelworm killing agent. The organic material is nutshell powder, sawdust or crop straw. The application method comprises the following steps: the vegetable field is cleaned in summer with high temperature and good sunlight, the eelworm killing agent is broadcasted, the subsoiling and the ridge forming processes are performed, a film is covered, and the irrigation is performed; and after the vegetable field is sealed for 14 to 21 days, the film is disclosed, the soil is plowed, and the vegetable field is air-cured for 5 to 7 days. The facility vegetable field eelworm killing agent and the application method thereof can be applied to prevent and control vegetable root knot nematode for more than 30 vegetable crops such as facility vegetable field cucumber, tomato, kidney bean, melon and celery, have simple technique, sufficient raw materials and low price, and prevent and control the vegetable root knot nematode by more than 70 percent.

Description

technical field [0001] The invention relates to a soil disinfectant, in particular to a nematocide for protected vegetable fields and a use method thereof. Background technique [0002] In recent years, with the rapid expansion of the area of ​​protected vegetables, vegetables with high economic value such as cucumbers and tomatoes have been planted year after year, resulting in the spread of root-knot nematode disease. Root-knot nematode mainly damages more than 30 kinds of vegetables such as cucumbers, tomatoes, kidney beans, melons, and celery, among which cucumbers, tomatoes, and celery suffer the most. Generally, damage can lead to a 10-20% reduction in vegetable production, and serious damage can result in a 30-60% reduction in production. [0003] Root-knot nematodes mainly infect the roots of vegetables. The affected plants show more lateral roots or fibrous roots than normal plants. After the lateral roots or fibrous roots are infected, spherical or irregular nodu...
