Abstract

The invention discloses a double-layer microbial fertilizer and a preparation method thereof and belongs to the technical field of fertilizers. The fertilizer is composed of 40-50 parts of an inorganic compound fertilizer, 18-25 parts of an inner layer film coverage agent, 60-80 parts of an organic fertilizer, 3-5 parts of binder and 20-25 parts of an outer layer film coverage agent; the inorganic compound fertilizer serves as an inner layer fertilizer core and is wrapped by the inner layer film coverage agent, the organic compound fertilizer is bonded outside the inner layer film coverage agent, and finally the surface of the organic compound fertilizer is wrapped by the outer layer film coverage agent, so that a final product is obtained. The double-layer microbial fertilizer is rich in multiple types of nutrient elements, has a quite good controlled release effect and can maintain the stable and low release speed in the entire release process of nutrient, the release amount of different types of nutrient is matched with nutrient required by crops in the growing cycle, all nutritional constituents required by the crops in different growing periods can be provided, the yield-increasing effect is obvious, the attack rate of plant diseases and insect pests is low, the generation rate of malformed fruits is low, and extremely high application and popularization value is achieved.

Description

technical field [0001] The invention relates to a slow and controlled release fertilizer, in particular to a double-layer microbial fertilizer and a preparation method thereof, belonging to the technical field of fertilizers. Background technique [0002] Fertilizers are an important guarantee for increasing grain production. In today's world, chemical fertilizers contribute 50% to increasing grain production. China is the country that uses the most fertilizers in the world, but at present, the total amount of chemical fertilizers in my country is insufficient, the structure of fertilization and fertilizers is unreasonable, the distribution of fertilizers is unbalanced, and waste is serious. The utilization rate of chemical fertilizers is low, and they are not absorbed by crops after application. Fertilizers enter the environment in large quantities, causing pollution to the environment. It not only destroys land resources, but also poses a threat to human health. According...
