Soil disinfection and soil remediation combined technology

Abstract

The invention provides a combination technology of soil disinfection and soil restoration, including preparation before soil disinfection, soil disinfection and soil restoration. Before soil disinfection: the plowing depth is 40-50cm; the border height is 20-30cm; the height between the film and the soil in the border is 10-20cm. The soil disinfectant used includes the following components: dithiocarbamate, sodium formate, 2-chloroisobutyl nitrite, borax, cyclodextrin, laminarin, and phthalimide. The soil remediation agent used includes the following components: microbial powder, sodium alginate, 2-hydroxybenzoic acid-5-sodium sulfonate, β-cyclodextrin, sodium caseinate, medical stone powder, EDTA-iron, Corn protein peptide, polyglutamic acid, polyacrylamide, earth wattle powder. The technology of the invention has obvious control effects on root rot, canker, fusarium wilt, verticillium wilt, bacterial wilt and stem base rot of plants, and at the same time has obvious improvement on soil properties.

Description

technical field [0001] The invention relates to a soil conditioning and restoration technology, in particular to a combined soil disinfection and soil restoration technology, which belongs to the field of agricultural technology. Background technique [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 effo...

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
