Special fermented composite coating fertilizer for wheat base fertilizer and preparation method thereof

Abstract

The invention discloses a special fermented composite coated fertilizer for a wheat base fertilizer. The special fermented composite coated fertilizer is characterized by being prepared from the following raw materials in parts by weight: 35-39 parts of licorice residue, 40-44 parts of fresh vinasse, 25-28 parts of urea, 4-6 parts of wood vinegar, 80-88 parts of chicken manure, 10-14 parts of turfy soil, 7-9 parts of clay, 8-10 parts of peat, 55-59 parts of straw, 6-8 parts of EM (effective microorganisms) bactericide, 12-15 parts of calcium superphosphate, 16-19 parts of potassium sulfate, 15-18 parts of sodium metaphosphate, 8-11 parts of potassium tripolyphosphate, 7-9 parts of soil conditioner and a proper amount of water. The fertilizer has balanced nutrition, contains nitrogen, phosphorus and potassium, and also contains rich substances such as organic acids by fermenting organic substances, so that the problems of soil hardening and the like are solved; by adding the soil conditioner, the fertilizer has the effects of increasing the fertility and promoting nutrition absorption of plants; by adopting a urea melt coating procedure, the slow-release effect is significant, the fertility is lasting, the planting cost is reduced, and both production and income of wheat are increased.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a special fermented composite coated fertilizer for wheat base fertilizer and a preparation method thereof. Background technique [0002] At present, my country's agriculture is developing rapidly. my country is not only a big agricultural country, but also a big country in the use of fertilizers. The application and development of fertilizers are getting more and more attention. Fertilizer plays a very important role in the process of wheat planting, affecting the quality and yield of wheat. At present, most of the fertilizers used for wheat planting are nitrogen, phosphorus and potassium compound fertilizers. Although they can meet the growth needs of wheat in a short period of time, long-term use will damage the soil aggregate structure, which will easily cause soil compaction, soil hardening, and reduce soil fertility. At the same time, pure inorganic fertilizers have low fertili...

Problems solved by technology

At present, most of the fertilizers used for wheat planting are nitrogen, phosphorus and potassium compound fertilizers. Although they can meet the growth needs of wheat in a short period of time, long-term use will damage the soil aggregate structure, which will easily cause soil compaction, soil hardening, and reduce soil fertility. At the same time, pure inorganic fertilizers have low fertilizer efficiency and cannot evenly distribute the various nutrients needed for wheat growth, thus affecting the growth of wheat
