Organic fertilizer and its manufacture method

Abstract

The composition of ecological fertilizer comprises (by weight portion) straw powder 30-70, fungous preparation 1-20, coal humic acid 5-30, urea 5-25, ground phosphate rock 3-25, potassium mineral powder 3-30 and lime 0.3-15. It is made up by adopting biological method, and is low in production cost, and is an organic composite fertilizer applicable to grain crops, vegetables, fruit tree, tobacco and economic crops of acid soil, alkali soil and neutral soil, and its fertilizer effect is good.

Description

(1) Technical field [0001] The invention relates to an organic compound fertilizer with complete nutrition, high efficiency and no environmental pollution for food crops, vegetables, fruit trees, tobacco and other economic crops used in acidic, alkaline and neutral soils, specifically an ecological fertilizer and其制造方法。 Its manufacturing method. (2) Background technology [0002] The growth of various food crops, vegetables, fruit trees, tobacco and other cash crops requires fertilizers. Since entering the stage of modern agriculture, the planting industry has applied a large number of chemical fertilizers, the disadvantage of which is not only to bring serious harm to the environment and people's health, but also that the high yield and quick effect of chemical fertilizers have reached the limit; [0003] In order to protect the ecological environment, people have developed organic fertilizers. At present, there are still some shortcomings in the production of organic fertilizers...

AI Technical Summary

Problems solved by technology

There are still some deficiencies in the production of organic fertilizers at present: some production methods still adopt the acid method, such as the content described in the publication materials of No. 99127128.9 patent application and the publication materials of No. 99122188.5 patent application, and its production process is the same as the principle of chemical production. The process is complicated and primitive, and the cost of using acid and alkali is high. After use, some chemical components remain in the soil, causing pollution to the soil; the number of beneficial microorganisms in some biological fertilizers does not reach the minimum limit specified by the Ministry of Agriculture of China ( ≥100 million / ml), the number of miscellaneous bacteria exceeds the maximum limit (≤20%); some biological fertilizers are added with some chemical fertilizers, ignoring the inhibitory effect of chemical fertilizers on beneficial microorganisms, reducing or losing the role that beneficial microorganisms should play Some use the method of granulating beneficial microorganisms and chemical fertilizers separately, the production process is complicated, and the fertilizer nutrients are uneven; some organic fertilizers are produced using similar composting or mushroom material fermentation methods, which will lead to mixed bacteria For example, the material published in patent application No. 87104531 adopts this production method, and the raw materials used include grain and vegetable oil, which are expensive and difficult to use on a large scale; some organic compound fertilizers use poultry manure or furfural slag Distiller's dregs are accumulated and fermented with chemical fertilizers. The source of raw materials is limited, and the inorganic and organic substances in the composition have not been biodegraded, activated, compounded, or fully complexed (chelated), and the harmful effects of chemical fertilizers still exist. Residues and pollution to the environment, the utilization rate of nutrients is still very low and other issues
