Problems solved by technology

[0002] With the development of modern agriculture, the soil of our country's existing cultivated land has been over-exploited and used, especially for the cultivation of vegetables, flowers, fruits and other crops. Continuous planting will cause a large loss of soil nutrients, resulting in serious acidification and hardening, and soil deterioration. , crop soil-borne diseases, especially viral diseases, are difficult to be effectively controlled, resulting in damage to the soil structure and poor crop growth. At the same time, the application of chemical fertilizers and pesticides is increased, leading to a vicious circle
[0003] In order to improve the land burden caused by modern agriculture, people have made a lot of efforts to kill viruses in the soil and restore soil properties through various methods; however, the overall effect is not obvious; the resistance of various pathogens is constantly increasing , which seriously threatens the growth of plants, and the excessive application of pesticides and chemical fertilizers seriously damages the soil structure, and even makes it lose its original repair ability
[0004] The prior art has the following defects: (1) soil disinfection and soil remediation are not applied together; (2) root rot, canker, fusarium wilt, verticillium wilt, bacterial wilt, and stem base rot occur seriously , cannot be effectively controlled; (3) the ability of existing technologies to improve soil properties is poor; (4) the destruction of soil structure seriously reduces the ability of plant roots to absorb nutrients in the soil, the utilization rate of fertilizers is low, and the yield is affected

Abstract

The invention provides soil disinfection and soil remediation combined technology. The technology includes the steps of preparation before soil disinfection, soil disinfection and soil remediation. Before soil disinfection, the ploughing depth ranges from 40 cm to 50 cm, the ridge height ranges from 20 cm to 30 cm, and the height between each film and soil in the corresponding ridge ranges from 10 cm to 20 cm. An adopted soil disinfection agent comprises the following components of dithiocarbamic acid, sodium formate, nitrite 2-chloroisobutyl, borax, cyclodextrin, laminarin and phthalimide. An adopted soil remediation agent comprises the following components of microorganism bacterium powder, sodium alginate, 2-hydroxybenzoic acid-5-sodium sulfonate, beta-cyclodextrine, sodium caseinate, medical stone powder, EDTA-iron, corn protein peptide, polyglutamic acid, polyacrylamide and cortex pseudolaricis powder. The soil disinfection and soil remediation combined technology has remarkable effects on the root rot, canker, wilt, verticillium wilt, bacterial wilt and basal rot of plants and meanwhile has remarkable improvement effects on the soil properties.
