Embodiment Construction

[0015] The present invention will be described in further detail below in conjunction with specific embodiments.

[0016] Such as figure 1 as shown, figure 1 It is a flow chart of a high-temperature flame steam extermination method for root-knot nematode provided by an embodiment of the present invention. The method includes the following steps:

[0017] Step S100: deep plowing the soil of the greenhouse which is idle after harvesting the crops to a predetermined depth and sun-steaming for a predetermined time.

[0018] Optionally, the deep plowing of the greenhouse soil to a predetermined depth may be between 20-40 centimeters, preferably 30 centimeters. By deep plowing the soil, the root-knot nematodes that breed deep in the soil can be turned up on the soil surface or shallow, so that the subsequent steps can more effectively kill the root-knot nematodes when adjusting the pH of the soil and killing insects.

[0019] Optionally, the greenhouse soil after deep plowing is...

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 ...
