Preparation method of fertilizer composition

Abstract

The invention discloses a preparation method of a fertilizer composition. The method comprises the steps of material preparing, stacking, chemical spraying, turning, stirring, screening and the like. The fertilizer composition prepared through the method is high in major element content, medium element content and trace element content, growth of plants is facilitated, substance accumulation of nutrients in plant bodies is richer, the plant quality is improved, the voidage of soil can be increased simultaneously, the effects of fertilizer conservation and water conservation are good, the air permeability of soil is excellent, and the growth requirement of the plants can be fully met. According to the preparation method of the fertilizer composition, use of chemical agents in fertilizer preparation is reduced, the soil is improved indirectly, the phenomenon of soil hardening is avoided, the environment of the soil is improved, and the fertility of the soil is increased.

Description

technical field [0001] The invention relates to a preparation method of an agricultural fertilizer, in particular to a preparation method of a composition which is composed of pure natural organic matter and can not only improve soil but also promote plant growth. Background technique [0002] With the decrease of arable land, more and more people pay more and more attention to the unit yield. Organic fertilizers contain the nutrients necessary for crop growth. The characteristics of nutrients are that the organic matter has a large amount of adsorption and the nutrients are not easy to lose. The other is that the nutrients are complete and easy to decompose. Absorbed and utilized by crops, the application of organic fertilizers not only supplements soil nutrients, but also absorbs the nutrients needed for crop growth from the soil from the perspective of nutrient cycling, and regenerates the nutrients in the soil, reducing the loss of soil nutrients. The application of orga...

Compound fertilizer has the advantages of high nutrient content, less auxiliary components and good physical properties. It plays a very important role in balancing fertilization, improving fertilizer utilization rate, and promoting high and stable yield of crops. However, the proportion of nutrients in compound fertilizer is fixed, and different Soil, different crops require different nutrients, and long-term use of compound fertilizers will cause soil compaction, reduce soil porosity, and soil erosion will be more serious

At present, there are some pure natural organic fertilizers on the market, but their preparation methods are either too simple, the nutrients in natural organic fertilizers are not fully utilized, or the preparation methods are too complicated, and the growth cost remains high, which is not conducive to the promotion and utilization of organic fertilizers.
