Composition for accelerating agricultural chemical degradation as well as preparation method and application thereof

Abstract

The invention discloses a composition for accelerating agricultural chemical degradation and a preparation method and application thereof. The composition is prepared by fermenting a mixture comprising rice bran, oyster shell powder and egg powder as main components. When the composition is prepared, the rice bran and the egg powder are sterilized firstly; and then the rice bran, the egg powder and the oyster shell powder are weighed, uniformly stirred, and fermented to obtain a product, namely the composition. According to the composition, under the condition that an existing planting mode isnot changed, the raw material substrates which are the rice bran, the oyster shell powder and the egg powder are fermented through composite strains, and the obtained composition can rapidly degraderesidual agricultural chemicals in soil, improve the soil and reduce the residual agricultural chemicals in plants.

Description

Technical field [0001] The invention belongs to the technical field, and specifically relates to a composition capable of rapidly degrading pesticides and hormones remaining in the soil, and a method for preparing the composition and the application of the composition in reducing plant pesticide content. Background technique [0002] Nowadays, pesticides (including hormone plant regulators and herbicides, etc.) are generally used when planting crops. Without pesticides, crop cultivation has almost no economic value, and growers may even lose money. In the various stages of plant cultivation, such as seed preservation, germination, seedling cultivation, transplanting, growth, flowering, fruit maturity, more or less chemical drugs such as pesticides, herbicides, antibiotics and hormones will be exposed to these drugs. After being absorbed by plants, they remain in the roots, stems, leaves, flowers and fruits of plants. What is more serious is that after humans consume the edible pa...

Problems solved by technology

[0002] Nowadays, pesticides (including hormonal plant regulators and herbicides, etc.) are generally used when planting crops. If pesticides are not used, crop planting has almost no economic value, and growers may even lose money

In each period of plant planting, such as seed preservation, germination, seedling raising, transplanting, growth, flowering, fruit maturity, more or less will be exposed to pesticides, herbicides, antibiotics, hormones and other chemical drugs, these drugs After being absorbed by plants, they remain in the roots, leaves, flowers and fruits of plants. What's more, after humans eat the edible parts of plants, a large part of these chemicals will remain in the human body, which is harmful to human health.

[0003] In the field of planting Chinese medicinal materials, chemical drugs remain in the plants, which not only affects the quality of medicinal materials, but also significantly reduces the efficacy of medicinal materials.

[0004] In addition, the extensive use of pesticides in the process of planting has largely destroyed the balance of the soil microbial environment, which is not conducive to the degradation of pesticides by microorganisms. Therefore, the amount of pesticides absorbed by plant roots increases, and pesticide residues cause damage to both soil and plants. pollution

[0005] In view of the serious phenomenon of pesticide residues in plants and soil, the current methods include aging treatment and spraying a large amount of water. These methods can reduce some pesticide residues in plants, but for long-acting pesticides, the effect of aging treatment and spraying water very limited
