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 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

Abstract

The invention discloses a soil insecticide. The soil insecticide is prepared from the following raw materials in parts by weight: 8 to 15 parts of sulfur, 6 to 10 parts of coptis chinensis, 3 to 8 parts of muskroot-like semiaquilegia roots, 5 to 10 parts of radix stemonae, 8 to 12 parts of common carpesium fruits, 6 to 10 parts of fructus forsythia, 5 to 10 parts of divaricate saposhnikovia roots, 5 to 8 parts of ginkgo biloba sarcotesta, 50 to 150 parts of solvent, 3 to 8 parts of emulsifier, 0.1 to 0.4 parts of thickener, 3 to 5 parts of enhancer, 0.1 to 1 part of defoamer, and 25 to 40 parts of deionized water. According to the soil insecticide disclosed by the invention, the selected natural raw materials are mild in drug properties, basically free of toxic and side effects on people and livestock, and good in insecticide and antimicrobial effects after being scientifically configured by adopting modern science and biotechnology; an insecticide killing device is simple in structure, convenient to operate, capable of retaining a high-temperature insecticide in soil for a long time and thoroughly killing harmful germs and insecticides in the soil, long in drug effect duration, and high in safety; according to the soil insecticide and a use method thereof, high-temperature steam and the insecticide are combined, physical and chemical methods act on the soil simultaneously when the high-temperature insecticide is sprayed into the soil, so that the sterilization and insecticide killing effects are good and the working efficiency is high.
