Problems solved by technology

[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 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; radiation disinfection is used to sterilize and sterilize with rays with strong penetrating power and energy, such as gamma rays of cobalt 60. This method is costly and difficult to use for ordinary farmers ; Although baking and other methods are environmentally friendly, the heat dissipates 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, etc., and is not suitable for large-scale arable land. Direct soil treatment, and baking will destroy the nutrient 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

Abstract

The invention discloses an efficient pesticide, which is prepared from the following raw materials in parts by weight: 5-8 parts of ginkgo bilobal peel, 8-15 parts of stone-like omphalia, 6-10 parts of Chinese prickly ash, 3-8 parts of muskroot-like semiaquilegia roots, 5-10 parts of fructus cnidii, 8-12 parts of thunder god vine, 6-10 parts of fructus kochiae, 5-10 parts of divaricate saposhnikovia roots, 80-120 parts of a solvent, 3-8 parts of an emulsifier, 0.5-0.8 part of a thickening agent, 3-5 parts of an anti-freezing agent, 1-2 parts of a defoaming agent and 30-50 parts of rice water. By a modern technological biotechnology, the selected natural raw materials are scientifically prepared, so that the efficient pesticide disclosed by the invention is mild in medicine property, free of a toxic or side effect on people and livestock basically and good in insecticidal and antibacterial effects; an insect-killing device is simple in structure and convenient to operate; a high-temperature pesticide can be reserved in soil for a long period of time; harmful bacteria and insects in the soil are thoroughly eliminated; and the efficient pesticide is high in effective duration and high in safety. By combination of high-temperature steam and the pesticide, the high-temperature pesticide is sprayed into the soil; and a physical method and a chemical method simultaneously act on the soil, so that the antibacterial and insecticidal effects are good; and the work efficiency is high.
