Biological composite fertilizer

Abstract

The invention relates to a biological composite fertilizer, and concretely relates to a biological composite fertilizer. The biological composite fertilizer is characterized by being composed of the following raw materials: 7-9 parts of a microbial composite inoculant, 3-5 parts of nitrogen-fixing bacteria, 3-5 parts of phosphobacteria, 3-5 parts of potassium bacteria, 5-15 parts of humic acid, 10-20 parts of amino acids, 4-6 parts of chitin, 1-3 parts of polypeptide, 5-15 parts of medium and trace elements, 5-15 parts of an algae fertilizer, 8-10 parts of zeolite powder, and 1-3 parts of a synergist. The fertilizer is capable of obviously improving soil fertility and microbial environment in soil, and has effects of resisting insect diseases. The fertilizer is low in cost, simple in production technology, long in fertilizer efficiency and free of pollution. Nutrition balance is reached through scientific reasonable formula, nutrients demanded by crop growth are satisfied, large-molecular natural organic compounds are accelerated to be decomposed into an organic fertilizer by adding the inoculants, organic pollutants are decomposed, the capability of crop absorbing nutrients is effectively improved, fertilizer waste is reduced, damage of chemical fertilizers to soil is reduced, and thus nutrition balance is realized, nutrients demanded by crops are satisfied, and economic benefit of crops is improved.

Description

[0001] technical field [0002] The invention relates to a compound fertilizer, in particular to a biological compound fertilizer. Background technique [0003] In the prior art, the development from farmyard manure to chemical fertilizers, the application of chemical fertilizers has led to a rapid development of agricultural production, but chemical fertilizers pollute the environment, compact the soil, destroy the soil structure, and gradually reduce or even exterminate many beneficial microorganisms in the soil, thus making the soil fertility decline, crop quality deterioration and other defects. In addition, the application of organic fertilizers on the soil where chemical fertilizers have been applied, due to the lack of decomposition of beneficial microorganisms, the nutrients cannot be released for absorption and utilization by crops, so the fertilizer utilization rate is low and the fertilizer efficiency is poor. In order to improve soil fertility, we have to increa...

Problems solved by technology

This runs counter to the development of ecological agriculture and the realization of pollution-free production advocated by the country. The basic reason is that at present, my country does not have industrialized organic fertilizers that are widely accepted by farmers. Using organic fertilizers as top dressing means direct application of human and animal fertilizers. Manure is dirty, smelly and time-consuming to transport and apply, making farmers reluctant to use it

[0004] At present, some provinces have applied potassium bacterial fertilizers on a large scale, and achieved significant yield-increasing effects. This is an important development approach to solve the potassium deficiency in agriculture, but it also has limitations. It cannot solve the problem that agriculture must provide nitrogen and phosphorus fertilizers through the application of chemical fertilizers.
