[0002] my country is one of the earliest countries to use pesticides and has a very long history. In the late 1980s, organochlorine pesticides were used for sterilization, which had a great impact on the soil. With the development of pollution-free agricultural products in my country Vigorously promote the implementation, high-efficiency, low-toxicity, and low-residue pesticides are gradually favored by consumers, and the widely used pesticides are still chemical preparations after all. Although they have a good sterilization effect, this low-residue chemical It will also cause pollution to the environment, have toxic and side effects on humans and animals, and is not conducive to long-term development

Embodiment 1
[0012] A soil sterilizer, made from the following raw materials in parts by weight: 5 parts of saponins, 12 parts of cnidium, 10 parts of turnips, 13 parts of hibiscus bark, 10 parts of sulfur, 10 parts of pumpkin seeds, and 5 parts of crane grass buds , 12 copies of Dafengzi.
[0013] The preparation method of a kind of soil sterilant described in the present embodiment, after the Chinese honey locust, cnidium fruit, Chinese weed, hibiscus bark, sulfur, pumpkin seeds, crane grass buds, and Dafengzi are extracted with super-zero carbon dioxide according to the proportion , a concentration of 4g / ml extract.
[0014] The method of use is to sprinkle the extract into the soil when cultivating the land, and the dosage is 1.1 kg per mu of land.
Embodiment 2
[0016] A soil sterilizer, the soil insecticide is made of the following raw materials in parts by weight: 7 parts of acacia, 9 parts of Cnidium, 12 parts of turnip, 10 parts of hibiscus bark, 13 parts of sulfur, and 8 parts of pumpkin seeds , Crane grass buds 8 parts, Dafengzi 11 parts.
[0017] The preparation method of a kind of soil sterilant of the present invention, after adopting ultra-zero boundary carbon dioxide to extract the honey locust, cnidium fruit, turnip, hibiscus bark, sulfur, pumpkin seeds, crane grass buds and japonica according to the proportion, Extract at a concentration of 3 g / ml.
[0018] The method of use is to sprinkle the extract into the soil when cultivating the land, and the dosage is 1.1 kg per mu of land.

Abstract
A disclosed soil sterilizing agent is prepared from the following raw materials in parts by weight: 5-10 parts of gleditsia sinensis Lam, 8-12 parts of fructus cnidii, 10-15 part of ulmus macrocarpa Hance, 8-13 part of cortex pseudolaricis, 10-16 part of sulfur, 5-10 part of pumpkin seed, 5-10 part of radix agrimoniae pilodae, and 8-12 part of chaulmoogratree seed. The soil sterilizing agent employs modern science and technology and biological technology, the selected raw materials are scientifically matched, and the agent is a pollution-free wide-spectrum soil special-purpose pesticide which is extracted through supercritical carbon dioxide. Compared with a water decoction process in the prior art, the effective compositions are relatively easily extracted, the traditional Chinese medicine utilization rate is high, the insecticidal effect and the sterilizing effect are relatively good, and the drug property is mild. The agent is capable of effectively killing insects, bacteria and ova in soil without polluting environment, is basically free of toxic and side effect on human and animals, is long in persistent period, low in usage amount and high in safety.
Description
technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a soil sterilizer. Background technique [0002] my country is one of the earliest countries to use pesticides and has a very long history.
