Wood vinegar soil disinfectant and preparation method thereof

Abstract

The invention relates to technology of disinfecting soil and preventing and curing crop pests, in particular to a wood vinegar soil disinfectant and a preparation method thereof, which solves the problem that the yield and the quality of vegetables are influenced because of serious silborne pests in facility vegetable fields. The wood vinegar soil disinfectant comprises the following compositions that: each 90 to 95 liters of refined wood vinegar contains 1.0 to 2.0 kilograms of blue vitriol, 1.0 to 2.0 kilograms of iron vitriol, and 5 to 10 kilograms of abamectin technical products. The preparation method comprises the following steps: weighting up the blue vitriol, the iron vitriol and the abamectin technical products in portion by weight; pouring the materials into a container filled with the refined wood vinegar respectively; fully dissolving the blue vitriol, the iron vitriol and the abamectin technical products by fully stirring; evenly mixing the materials; loading the mixture into a plastic container; and obtaining the finished product. The wood vinegar soil disinfectant and the preparation method thereof have the advantages of friendly environment, simple process and low cost. The wood vinegar soil disinfectant can be diluted by 300 to 500 times by adding water, and then is irrigated into crop roots or sprayed on the soil surface in practical application.

Description

technical field [0001] The invention relates to soil disinfection and crop disease and insect pest control technology, in particular to a wood vinegar liquid soil disinfectant and a preparation method thereof. Background technique [0002] my country's vegetable planting area exceeds 19.7 million hectares, of which the protected vegetable cultivation area reaches more than 2.5 million hectares, accounting for more than 80% of the world's total protected vegetable area. Compared with developed countries, my country's protected vegetable fields have high land use intensity, high utilization frequency, high multiple cropping index, and high planting density. The facility vegetable field is recycled, and there is basically no leisure period. The high temperature, high humidity, closed or semi-closed environment of the facility vegetable field lead to secondary salinization of the soil, serious soil-borne diseases, frequent occurrence of vegetable diseases and insect pests, and ...
