Efficient environment-friendly fertilizer and preparation method thereof

Abstract

The invention discloses an efficient environment-friendly fertilizer and a preparation method thereof. A fertilizer particle has a spherical structure comprising active balls, a coating layer and a quick-acting layer from outside to inside. According to the invention, the fertilizer particle is designed into a spherical structure comprising an active ball, a coating layer and a quick-acting layerfrom inside to outside; the active ball is used for fixing nutritional ingredients through high-density biochar; then charcoal immobilized with nutrient substances and composite strain liquid are mixed for fermentation, and strains are immobilized; urea, a decomposed organic fertilizer and ground phosphate rock activated by organic acid serve as main components of the coating layer, so that fertility is effectively provided for plants for a long time, and the coating layer is a part capable of providing fertility for a long time. According to the invention, microorganisms serve as one part ofthe fertilizer, the influence of application of a large number of inorganic fertilizers on soil texture is reduced, environmental protection and saving are achieved, long-term utilization of land resources is facilitated, and the soil environment is continuously improved while nutrients urgently needed by plants are met.

Description

technical field [0001] The invention belongs to the technical field of fertilizer processing, and in particular relates to a high-efficiency and environment-friendly fertilizer and a preparation method thereof. Background technique [0002] As a large agricultural country, China needs to consume a large amount of fertilizers every year. Fertilizers are mainly divided into inorganic fertilizers and organic fertilizers according to different raw materials. Among them, inorganic fertilizers are what we often call chemical fertilizers. They are inorganic compounds containing nitrogen, phosphorus, potassium and other elements. As a fertilizer with active ingredients, the cost is low and the effect is quick. Organic fertilizer is a material containing carbon, hydrogen and oxygen that comes from plants or animals and provides nutrition for plants. It is rich in a large number of beneficial materials and can be decomposed by microorganisms , so as to improve the physical and chemica...

Problems solved by technology

[0003] However, inorganic fertilizers are water-soluble. After a large amount of inorganic fertilizers are applied, only a small part of the inorganic fertilizers will be absorbed by plants, and a large amount of active ingredients cannot be absorbed by crops. With the loss of water flow, it will cause damage to soil quality and water resources. Pollution and loss of fertilizers. Organic fertilizers are environmentally friendly and can improve the air permeability of the soil. They are suitable for long-term use, and they have long fertilizer effects, multiple nutrients, and high fertilizer utilization rates. However, they need microbial decomposition to produce nutrients that can be absorbed by plants. The effective ingredients used are slow to take effect in a short period of time, and cannot achieve immediate results. In the early stage of using organic fertilizers on the land, they need to be used together with inorganic fertilizers. Organic fertilizers need to be fermented so that they will not have obvious negative effects on the soil. How to reduce the negative effects of fertilizers and how to improve the sustainable development of land resources is one of the problems that the fertilizer industry needs to solve. In order to solve this problem, the present invention provides the following technical solutions
