Composite fertilizer

Abstract

The invention discloses a composite fertilizer which is prepared from 7-10 parts of Chinese trumpet creeper, 8-15 parts of astragalus smicus, 5-10 parts of sickle alfalfa, 2-5 parts of sweet clover, 3-6 parts of sun hemp, 1-5 parts of sesbania cannabina, 3-6 parts of amorpha fruticosa, 0-4 parts of duckweed, 2-8 parts of eichhornia crassipes, 4-9 parts of herb of alligator alternanthera, 3-8 parts of soybean pulp, 4-8 parts of tea leaf residues, 1-4 parts of plant ash, 4-8 parts of pea, 6-12 parts of broad beans, 10-15 parts of wheat bran and straw, an EM leavening agent and mountain spring water. As generally natural and green plant raw materials are adopted, the composite fertilizer disclosed by the invention is not only safe, environment-friendly, free of harmful substance pollution as no artificial additive or heavy metal is added, but also rich in nutrition component such as protein, vitamin and carotene, has the characteristics of improving the soil environment, improving the land fertility, and recycling natural resources, and also has the characteristics of recycling resources and protecting the air environment as wheat bran and straw which are regarded as agriculture wastes in conventional agriculture are used as raw materials. The invention further discloses a method for preparing the composite fertilizer.

Description

technical field [0001] The invention relates to the field of agricultural production, in particular to a compound fertilizer for agricultural production. Background technique [0002] In agricultural production, the quality of fertilizers determines the quality of agricultural products. Therefore, the quality of fertilizers is very important. Most of the existing fertilizers use chemical fertilizers. In order to increase crop yields, various additives are often added to chemical fertilizers in excess. This leads to problems such as abuse of additives and excessive heavy metals in chemical fertilizers, which not only have adverse effects on human health, but also damage the natural environment such as soil quality. Contents of the invention [0003] The invention aims at the problems existing in the prior art, and provides a compound fertilizer which is environment-friendly, has no chemical additives and has excellent fertilizer efficiency.
