Humic acid biological fertilizer and its production method

Abstract

The invention produces a new humic acid bio-fertilizer, which comprises: using weathered coal and good organic (such as maize-ear and domestic animal manure) as main material with mineral phosphorus, potash fertilizer, chemical nitrogen fertiliser and microelement; ammonifying the wethered coal with size less than 80 items to mix with organic; accessing composite ferment fungus for solid fermentation to cut process and time. This invention reduces cost, overcomes shortcomings of high-nitrogen formula fertilizer, and has spread value.

Description

1. Technical field: [0001] The invention belongs to the technical field of a new type of environmentally friendly humic acid biofertilizer manufactured by fermenting and activating organic ore humic acid (weathered coal, lignite, peat), mineral phosphorus, potassium, trace element fertilizer, nitrogen fertilizer, and biological preparations in the chemical fertilizer industry. 2. Background technology: [0002] Fertilization of cultivated land in most parts of my country is unreasonable, especially the application of organic fertilizers has been severely reduced. With the development of the chemical fertilizer industry, the application of chemical fertilizers has risen sharply, and a large amount of inorganic chemical fertilizers N, P, and K fertilizers not only have low fertilizer utilization rates and high costs, but also lead to soil acidification and compaction, salinization, and nutrient imbalances, and crop yields have been hovering for a long time In the middle and lo...

Problems solved by technology

But the existing humic acid compound fertilizer not only does not have the good effect of bacterial fertilizer, but also adds a large amount of urea (15-25%) in the formula, so that the organic matter in the soil decreases gradually, and the base substances such as calcium and magnesium are deficient. As a result, the soil is acidified and compacted, the soil has no aggregate structure, and the conditions of water, fertilizer, air, and heat in the soil cannot be coordinated, and the high-concentration ammonia poisoning produced by the high-concentration urea in the hydrolysis process causes the leaves to turn yellow and chlorosis. The nitrogen loss caused by rainwater washing also causes water pollution
