Fertilizer with soil sterilization and insecticidal functions

Abstract

The invention belongs to the technical field of pesticide and fertilizer production and particularly relates to fertilizer with soil sterilization and insecticidal functions. The fertilizer is prepared from raw materials in parts by weight as follows: 30-55 parts of straw, 9-15 parts of biogas slurry, 3-7 parts of derris trifoliata, 2-5 parts of twotooth achyranthes root, 5-11 parts of mulberry leaf, 6-12 parts of acorus calamus, 2-5 parts of herba artemisiae annuae, 7-12 parts of pyrethrum, 0.5-2.5 parts of sulfur and 0.5-1.5 parts of edible salt. A preparation method of the fertilizer comprises steps of breaking, fermenting and packaging. Sterilization and insecticidal plants are added in the fertilizer preparation process and embedded in soil together with the fertilizer, so that sterilization and insect killing can be performed on the soil for a long time, harmful bacteria and insects in the soil can be eliminated thoroughly, effective duration of the pesticide is long, safety is high, and acid-base equilibrium of the soil can be regulated effectively.

Description

technical field [0001] The invention belongs to the technical field of pesticide and fertilizer production, in particular to a fertilizer with soil sterilization and insecticide functions. Background technique [0002] Sterilization and deworming are necessary tasks in the agricultural farming process. Sterilization and deworming are beneficial to kill bacteria and pests in the soil, reduce crop pests and diseases, and maintain the crop growth environment. At present, greenhouse vegetables have become mainstream products in the market, and most rural areas Vegetables and melons and fruits in the area are planted with plastic film or switched to greenhouses. The warm environment will make the bacteria and insects in the soil multiply and grow rapidly. In order to eliminate harmful bacteria and insects in the soil, before the crops are planted, People use chemical pesticides, radiation, and baking to kill insects on the soil.

[0002] Sterilization and deworming are necessary tasks in the agricultural farming process. Sterilization and deworming are beneficial to kill bacteria and pests in the soil, reduce crop pests and diseases, and maintain the crop growth environment. At present, greenhouse vegetables have become mainstream products in the market, and most rural areas Vegetables and melons and fruits in the area are planted with plastic film or switched to greenhouses. The warm environment will make the bacteria and insects in the soil multiply and grow rapidly. In order to eliminate harmful bacteria and insects in the soil, before the crops are planted, People use chemical pesticides, radiation, and baking to kill insects on the soil. Since the pesticides are easy to volatilize, part of them will be emitted during the spraying process, which cannot be fully utilized, and most of the chemical pesticides contain harmful substances. Harmful substances After growing, it remains in vegetables, seriously endangering human health and the growth of livestock. Some pests, especially root-knot nematodes, have a particularly strong ability to survive. Therefore, the use of chemical pesticides must be increased to kill fungi and insects, thus forming a vicious circle, causing Environmental pollution such as soil and water sources is serious; the sun exposure method is environmentally friendly, but it cannot eliminate insects in the deep soil. Insect method, the pollution is large, will destroy the soil nutritional structure, and cause serious damage to the soil. After insecticide and sterilization, it is necessary to re-add the nutrients needed by the crops to ensure the normal growth of the crops, and the cost is high.
