Compound microbial fertilizer

Abstract

The invention discloses a compound microbial fertilizer. The fertilizer includes the following ingredients in parts by weight: bamboo charcoal powder 10-30, peat powder 20-40, decomposed coal 10-30, humic acid 40-50, refined rice chaff 20-40, zeolite powder 8-12, liquid organic carbon 15-25, a nitrogenous fertilizer 5-10, a phosphate fertilizer 4-6, a binding agent 4-6, a potash fertilizer 2-4, a super absorbent polymer 3-5, a fertilizer containing middle elements and trace elements 2-4 and biological bacteria 0.6-1. The fertilizer provided by the invention has the characteristics of high complementarity, disease resistance, bacterium inhabitation, soil fertility improvement, soil activation, yield increase and quality improvement, can improve the effectiveness of inorganic nutrients, increase crop yield, improve the quality of agricultural products, reduce fertilizer consumption and improve soil, has no pollution and no abnormal odor and low consumption amount. Through adopting organic waste water to prepare organic matter, waste is turned into wealth and production cost is greatly saved. The fertilizer uses the easily available ingredients, has a simple production process and can be produced in a large scale without resource limits.

Description

technical field [0001] The invention relates to the technical field of fertilizer preparation, in particular to a compound microbial fertilizer. Background technique [0002] Due to the application of a large amount of chemical fertilizers, soil compaction, water quality decline, agricultural products are seriously polluted, and the entire farmland ecological environment and people's living environment are affected. How to maintain the sustainable development of my country's agriculture has attracted great attention from governments at all levels. Especially after my country's accession to the WTO, my country's agriculture has been severely challenged. To develop export-earning agriculture, we must vigorously promote the development of green food and pollution-free food. Moreover, under the impact of the international financial crisis, the traditional chemical fertilizer industry is in deep trouble. Fertilizers have a very good room for development, and the reason is due to t...

Problems solved by technology

An authoritative department estimates that in the next five years, the annual demand for microbial fertilizers will reach 30% of the amount of chemical fertilizers, and the market capacity will reach 42 million tons. However, the current annual production of microbial fertilizers in my country is less than 3 million tons, which is far from being able to meet market needs

[0004] Most of the existing technologies use microbial fermentation to obtain microbial fertilizers with a single function and then act on field crops

However, there are few reports on the use of multifunctional microorganisms, medium and trace elements, and liquid organic carbon to compound biological fertilizers to prevent and control soil-borne diseases, increase crop yields, and form beneficial effects on crop growth.
