Embodiment Construction

[0025] 1. Ditch and ridge. Ditch and ridge the soil in the greenhouse to form a box ridge. The section of the box ridge is as follows: figure 1 As shown, the ridge width AB is 85cm, the ridge height AE or BD is 25cm, and the box ridge bottom width AC is 30cm to carry out ridge ditching. In places where conditions permit, corn stalks and wheat straw can be chopped, mixed evenly with the soil, and then irrigated. The moisture content is not less than 30%.

[0026] 2. Initial disinfection. Cover the sky film and tidy it up, then cover the ground with a plastic film, bury and seal the film edge, cover the film with a soil depth of 5cm, and use high temperature and strong light for 20-25 days in summer.

[0027] 3. Remove the film and lower the ridge. Remove the plastic film on the ground, plow along the center of the ridge surface, and then fill the plowed and loose soil into the ditch to lower the ridge surface by 10cm.

[0028] 4. Add elements. According to the organic matt...

Abstract

A solar compound disinfection method for greenhouse soil is disclosed, which is used for disinfecting soil in a greenhouse via the steps of ditching and ridging, primary disinfection, film removal and ridge lowering, compound disinfection, compound planting and the like. The solar compound disinfection method for greenhouse soil disclosed by the invention can efficiently increase the temperature of soil while disinfecting soil with sunlight illumination, thereby being capable of eliminating pathogenic bacteria and killing nematodes, which is a harmless treatment process for soil and good for popularizing the efficient and ecological planting mode of greenhouse. The solar compound disinfection method for greenhouse soil disclosed by the invention has the advantages of being good in ecological environmental protection, strong in economy, wide in suitability and strong in operability, as well as is suitable for production for pollution-free fruits, vegetables and the like in greenhouse.

Description

technical field [0001] The invention relates to a disinfection method of greenhouse soil, in particular to a greenhouse soil method using multiple disinfection. Background technique [0002] Greenhouses are protection facilities for planting vegetables and other crops in winter. Due to continuous planting, a large amount of pathogenic bacteria of soil-borne diseases in the soil accumulates, which leads to continuous increase in planting costs and decline in product quality. How to do a good job in greenhouse soil disinfection is one of the key measures to do a good job in greenhouse production. In the past, chloropicrin was used for soil disinfection, resulting in excessive pesticide residues in the soil, which seriously affected the product quality. [0003] At present, soil disinfection mainly includes physical disinfection and chemical disinfection, and physical disinfection includes solar disinfection and steam disinfection. In recent years, some places have developed ...
