Embodiment 1

[0034] According to the soil disinfection method for the prevention and treatment of soil-borne diseases, the following steps are included:

[0035] (a), prepare soil: clean up the original plant residue and taproot in the soil, and carry out soil breaking and rotary tillage to obtain loose and flat soil;

[0036] (b), anaerobic disinfection treatment: spread and mix the organic matter particles of biological agents such as yeast, Trichoderma harzianum, phosphate solubilizing bacteria, nitrogen solubilizing bacteria, spray water after rotary tillage; then cover with TIF film, and then peel off the film open air;

[0037] (c), horseradish disinfection treatment: inject horseradish preparation for disinfection, cover the TIF film used during anaerobic disinfection, remove the film after covering and open the air, and germination test detects residue;

[0038] (d) After there is no disinfectant residue, add organic fertilizer and compound fertilizer for plant growth. After rotar...

[0054] Experimental example 2 Evaluation of the application effect of soil disinfection methods for preventing and controlling soil-borne diseases

[0055] In order to effectively judge the effect of the soil disinfection method for the prevention and treatment of soil-borne diseases of the present invention, select a park in the suburbs of Beijing where strawberries have been planted continuously for more than 10 years, and carry out this disinfection effect technology using the combination of anaerobic disinfection technology and horseradish soil disinfection technology test. The soil disinfection time is June 5, 2016; the variety of strawberries planted in the test site is: Hongyan; the planting density is 10,000 trees per mu. The park cooperates with this experiment to ensure that strawberries in this season adopt a unified source of seedlings, and the same water and fertilizer management and production and cultivation management. Disinfection test operation, pathogenic m...

Abstract

The invention provides a soil disinfection method for preventing and controlling soil-borne diseases, which comprises the steps of anaerobic disinfection and horseradish disinfection technology compound soil disinfection to obtain sterilized soil. The method of the invention can effectively reduce the quantity of soil-borne pathogenic microorganisms Fusarium, Phytophthora, and nematodes in planting land. It can effectively improve the survival rate of the plant during planting, promote the height of the plant and the thickness of the stem, make the growth more robust, and effectively reduce the dead seedling rate of the plant in the later stage of plant growth. The technology of the invention can be used as an effective technology for preventing and controlling plant soil-borne diseases.

Description

technical field [0001] The invention belongs to the technical field of soil pollution control and environmental restoration, specifically to the field of restoration, and mainly relates to a matrix restoration method, in particular to a soil disinfection method for semi-soil prevention and control of soil-borne diseases. Background technique [0002] With the increase of crop planting years and planting density, the occurrence of soil-borne diseases has increased year by year. Soil disinfection technology is a soil treatment technology that efficiently and quickly kills fungi, bacteria, nematodes, etc. in the soil to prevent and control soil-borne diseases, underground pests, and rodents. It applies chemical pesticides to the soil to kill bacteria, nematodes, and others. The phenomenon of harmful organisms, soil disinfection is generally carried out before crop sowing, which can well solve the problem of repeated cropping of high value-added crops, and significantly improve ...
