A device for using soil sterilizing insecticide

Abstract

The invention discloses a sterilizing and insecticidal drug for soil. The sterilizing and insecticidal drug is prepared from the following raw materials by weight: 5 to 10 parts of testa of ginkgo, 10 to 15 parts of leaf of Ailanthus altissima, 6 to 10 parts of alum, 8 to 12 parts of quisqualis, 5 to 10 parts of stemona root, 3 to 8 parts of pine needle piece, 5 to 10 parts of fructus forsythia, 5 to 10 parts of mulberry leaf, 40 to 120 parts of a solvent, 5 to 8 parts of an emulsifier, 1 to 3 parts of a dispersant, 3 to 6 parts of a reinforcing agent, 0.5 to 1 part of an antiseptic and 40 to 80 parts of deionized water. The sterilizing and insecticidal drug for soil is prepared from scientifically-proportioned natural raw materials by using modern science and biotechnology, has mild drug properties, is substantially free of toxic and side effect on human beings and animals and exerts good insecticidal and antibacterial effect. An insecticidal apparatus is simple in structure and convenient to operate, can retain the high-temperature insecticidal drug in the soil for a long time, thoroughly kills harmful bacteria and insects in the soil and has a long drug effect persistent period and high security. According to the invention, high-temperature steam and the insecticidal drug is combined together, the high-temperature insecticidal drug is sprayed out from the soil, physical and chemical approaches act on the soil at the same time, so good bacterium and insect killing effect is obtained and high work efficiency is realized.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a device for using soil sterilizing insecticides. 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. Since the pesticides are easy to volatilize, part of them will be emitted duri...

[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; 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
