Soil disinfection method for controlling soil-borne disease of protective vegetable

Abstract

The invention relates to procedures of soil disinfection to prevent and wipe out facility vegetable soil-borne diseases, operation steps are as follows: smoothing and watering the soil during the season with high temperature and good illumination to make sure relative humidity of the soil is 65%-80%, liming calcium cyan amide equably 6-100kg per 1000 m2 two days after watering, ploughing under to 30-40cm to make sure that the calcium cyan amide and the soil are mixed equably, confining the surface of the soil with transparent film and the booth or glasshouse totally for 12-20 days. The invention is mainly used for preventing and curing facility vegetable soil-borne diseases of cucumber, tomato, hot pepper, eggplant and so on, caused by pathogeny epiphyte, bacteria and wireworm. The invention prevents and cures soil-borne diseases greatly and duratively, offering vegetables nitrogen, decrease the accumulation of nitrate, accelerating plant growth. Said procedures of soil disinfection are novel to operate with easy steps, low cost, high efficiency and safety, significant economic benefit.

Description

technical field

[0001] The invention relates to a soil disinfection method, in particular to a soil disinfection method for preventing and controlling soil-borne diseases of facility vegetables. Background technique

[0002] In recent years, with the adjustment of the agricultural planting industry structure, the planting area of ​​economic crops such as melons, fruits, and vegetables has been expanding year by year, and vegetable facility cultivation techniques have been widely adopted. However, under the special conditions of protected cultivation, the growth and reproduction of soil-borne diseases and pathogenic bacteria are accelerated, the accumulation of pathogenic bacteria in the soil increases, and the prevalence of various crop bacteria, fungi, viruses and root-knot nematodes. If this kind of disease is not controlled in time, it will cause severe production reduction or even complete failure of commercial crops. Disinfecting the soil can better control the spread ...
