Soil sterilizing agent

Abstract

The present invention discloses a soil sterilizing agent prepared from the following raw materials in parts by weight: 5-10 parts of onions, 12-15 parts of cloves, 6-10 parts of star anise, 3-5 parts of semiaquilegia adoxoides, 8-10 parts of stemona, 8-12 parts of trollius chinensis, 6-10 parts of catechu, 5-8 parts of ginkgo biloba exocarp, 60-100 parts of a solvent, 3-8 parts of an emulsifier, 0.5-0.8 parts of a thickening agent, 2-5 parts of a preservative, 0.2-0.5 part of a defoamer, and 55-70 parts of deionized water. According to the soil sterilizing agent of the present invention, a biotechnology of a modern science and technology is used, the selected natural raw materials are scientifically allocated, the drug property is mild and the drug has no toxicity and side effect on human and animals, insecticidal and antibacterial effect are good, an insecticidal apparatus is simple in structure and easy to operate, and is capable of keeping a high-temperature sterilizing agent in the soil for a long time and thoroughly eliminating harmful bacteria and pests in the soil, and the sterilizing agent has a long pesticide effect duration and a high safety. According to the present invention, high-temperature steam and the sterilizing agent are combined, a high-temperature sterilizing agent is sprayed to the soil, and a physical method and a chemical method are used in the soil at the same time, therefore the sterilization and insecticidal effects are good, and the working efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a soil sterilizer. 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 diseases and insect pests, and maintain crop growth environment. At present, vegetables and fruits in most rural areas are planted with plastic film or Switch to greenhouse cultivation. Greenhouse vegetables have become the mainstream products in the market. Planting with plastic film or 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 ...

[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 diseases and insect pests, and maintain crop growth environment. At present, vegetables and fruits in most rural areas are planted with plastic film or Switch to greenhouse cultivation. Greenhouse vegetables have become the mainstream products in the market. Planting with plastic film or 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 the volatilization process will harm the staff; and most of them Chemical pesticides contain harmful substances. Harmful substances remain in vegetables after growth, seriously endangering human health and the growth of livestock. Some pests, especially root-knot nematodes, have a particularly strong survival ability, so the use of chemical pesticides must be increased to kill Bacteria and insects, thus forming a vicious circle, causing serious environmental pollution such as soil and water sources; radiation disinfection is used to sterilize and disinfect with rays with strong penetrating power and energy, such as gamma rays of cobalt 60. This method is harmful to ordinary farmers The cost is high, and the use is difficult; although baking and other methods are environmentally friendly, the heat is released quickly after baking, and the treatment efficiency is low. It is only suitable for treating a small amount of soil, such as the treatment of nutrient soil in the field of flower cultivation. It is not suitable for direct soil treatment on large-scale arable land, and baking will destroy the nutritional structure of 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
