Biochemical fertilizer and producing method thereof

Abstract

This invention provides a biochemical organic fertilizer containing rich active humid acid, N, P and K necessary for plants combined with biobacteriums and its production method, in which, the technical target of the fertilizer is: NPK 4-14%, organic matters 30-50%, available active bacteriums 0.2-1.0x108 / g, microelements 2-6%, active humid acid 10-20% and amino acid 2-5%. The production method includes: activation and biochemical process of organic materials, granulation, drying, cooling, screening, enveloping and measuring and packaging.

Description

technical field

[0001] The invention belongs to the field of fertilizers, and relates to a biochemical organic fertilizer and a production method thereof. Background technique

[0002] Soil and fertilizer are the two basic elements of agricultural production. Since the 1980s, a large amount of chemical fertilizers have been applied to arable land in my country, resulting in land degradation, soil compaction, soil fertility decline, reduction of organic matter and beneficial microorganisms, farmland ecological imbalance, product quality decline, and water resources and the environment have been polluted to varying degrees. potential threats to human health. Researching and developing new, pollution-free organic fertilizers is an important topic for agricultural scientists. Biochemical organic fertilizer has become an important organic fertilizer. Chinese patent 00125718.8 discloses an ecological organic fertilizer and a preparation method thereof. The patent uses organic w...
