Abstract

The invention discloses a soil disinfection and soil restoration method. The method comprises the following steps: deep ploughing soil, wherein the ploughing depth is 0.2-0.5m; disinfecting the soil with a soil disinfectant, wherein the consumption of the soil disinfectant is 1-2kg per mu; and restoring the soil with a soil restoration agent, wherein the consumption of the soil restoration agent is 10-30kg per mu. According to the soil disinfection and soil restoration method provided by the invention, soil disinfection and soil restoration can be simultaneously realized, and the microecological environment of the soil is improved, so that the fertility of the soil is increased, disease and pest attacks are resisted, and the consumption of pesticide is reduced, thereby being beneficial to environmental protection.

Example Embodiment

[0018] Example 1

[0019] A method for soil disinfection and soil remediation, which is carried out according to the following steps:

[0020] (1) Select southern acidic soil, pH 5.5, soil nematodes, and fungal diseases are serious, the soil is deeply plowed, and the depth of arable land is 0.4m;

[0021] (2) adopt soil disinfectant to sterilize soil, and the usage amount of soil disinfectant is 1.5kg per mu; Described soil disinfectant is made up of the material of following weight components: 15 parts of dimethyl disulfide, 14 parts of chitosan parts, 6 parts of furfural, 1 part of danamelon, 2 parts of alkyl dimethyl benzyl ammonium chloride, 1 part of sulfenamide, and 7 parts of bentonite;

[0022] (3) adopt soil remediation agent to repair soil, and the usage amount of soil remediation agent is 20kg per mu; Described soil remediation agent is made up of the material of following weight components: 4 parts of Bacillus subtilis inoculants (the content of viable bacteria is 5X10 8 pcs/g), 15 parts of magnesium carbonate, 15 parts of vermicompost, 2 parts of hydroxybutyl cellulose, 4 parts of diatomaceous earth, 6 parts of elm bark superfine powder, and 1 part of bovine bone meal.

[0023] In the soil restored by the above method, the soil pH rose to 6.9, and there was no recurrence of pests and diseases for 3 consecutive years. Compared with no soil disinfection and soil restoration, the yield of tomato was increased by 30%.

Example Embodiment

[0024] Example 2

[0025] A method for soil disinfection and soil remediation, which is carried out according to the following steps:

[0026] (1) Select the saline-alkali soil in the northern Cangzhou area, the pH is 8.5, the soil weeds and fungal diseases are serious, the soil is deeply plowed, and the depth of the arable land is 0.5m;

[0027] (2) adopt soil disinfectant to sterilize soil, and the usage amount of soil disinfectant is 2kg per mu; Described soil disinfectant is made up of the material of following weight components: 10 parts of dimethyl disulfide, 20 parts of chitosan , 5 parts of furfural, 2 parts of Dianron, 1 part of alkyldimethylbenzyl ammonium chloride, 2 parts of sulfenamide, and 8 parts of bentonite;

[0028] (3) adopt soil remediation agent to repair soil, and the usage amount of soil remediation agent is 30kg per mu; Described soil remediation agent is made up of the material of following weight components: 4 parts of nitrifying bacteria inoculants (the content of viable bacteria is 6×10 8 pcs/g), 15 parts of magnesium carbonate, 15 parts of vermicompost, 2 parts of hydroxybutyl cellulose, 4 parts of diatomaceous earth, 6 parts of ryegrass superfine powder, and 1 part of fish bone meal.

[0029] In the soil restored by the above method, the soil pH rose to 7.3, there was no recurrence of diseases and insect pests for 3 consecutive years, and the salinity and alkali conditions were greatly alleviated. Compared with no soil disinfection and soil restoration, the yield of eggplant was increased by 20%.

Example Embodiment

[0030] Example 3

[0031] A method for soil disinfection and soil remediation, which is carried out according to the following steps:

[0032] (1) Select the acidic soil in the south, the pH is 5.6, the soil is hardened, and the nematodes and fungal diseases are serious, and the soil is deeply plowed, and the depth of the arable land is 0.4m;

[0033] (2) adopt soil disinfectant to sterilize soil, and the usage amount of soil disinfectant is 1kg per mu; Described soil disinfectant is made up of the material of following weight components: 10 parts of dimethyl disulfide, 10 parts of chitosan , 5 parts of furfural, 1 part of Dianron, 1 part of alkyl dimethyl benzyl ammonium chloride, 1 part of sulfenamide, and 5 parts of bentonite;

[0034] (3) adopt soil remediation agent to repair soil, and the usage amount of soil remediation agent is 10kg per mu; Described soil remediation agent is made up of the material of following weight components: 1 part of Lactobacillus (the content of viable bacteria is 2×10 8 pcs/g), 2 copies of lactic acid bacteria (the content of viable bacteria is 4X10 8 pcs/g), 1 part of rhizosphere bacteria (the content of viable bacteria is 5X10 8 pcs/g), 10 parts of magnesium carbonate, 20 parts of vermicompost, 2 parts of hydroxybutyl cellulose, 3 parts of diatomaceous earth, 3 parts of amaranth superfine powder, and 2 parts of pork bone powder.

[0035] In the soil restored by the above method, the soil pH rose to 6.8, and there was no recurrence of diseases and insect pests for 3 consecutive years. Compared with no soil disinfection and soil restoration, the yield of carob was increased by 35%.
