Humic acid organic biological compound fertilizer and preparation process thereof

Abstract

The invention discloses a humic acid organic biological compound fertilizer and a preparation process thereof. The raw materials comprise the following components by weight: 10-20 parts of humic acid,20-30 parts of animal waste, 5-10 parts of crop straw, 3-5 parts of an organic bactericide, 1-3 parts of pine needle mulch, 1-3 parts of rice husk, 1-3 parts of rapeseed oil cake, 1-3 parts of walnutshell, 1-3 parts of zeolite powder, 1-3 parts of corncob, 3-5 parts of an inorganic conditioner and 3-5 parts of a microbial agent. The invention relates to the technical field of agricultural fertilizers. According to the humic acid organic biological compound fertilizer and the preparation process thereof, the organic bactericide can be added in the production process of the humic acid organicfertilizer to achieve comprehensive and quick sterilization treatment, so that the content of harmful bacteria in the humic acid bio-organic fertilizer is greatly reduced, the sterilization process issimple, production personnel do not need to spend a large amount of time in sterilizing and disinfecting the fertilizer, and the situation that crops planted in soil are seriously infected and damaged by the compound fertilizer with high harmful bacteria content is well avoided.

Description

technical field [0001] The invention relates to the technical field of agricultural chemical fertilizers, in particular to a humic acid organic biological compound fertilizer and a preparation process thereof. Background technique [0002] Humic acid fertilizer is a kind of organic fertilizer. Natural humic acid is formed by the decomposition of plant residues. It widely exists in dry soil, river mud and shallow buried weathered coal, peat, and lignite. Contains carbon, hydrogen, oxygen, nitrogen and other elements, and has a certain fertilizer effect, but most of them are insoluble in dry water. If they are combined with potassium, sodium, ammonium and other substances, they will be easily absorbed by plants as nutrients and humic. Acid and its products have many uses. In agriculture, humic acid fertilizers are made by combining nitrogen, phosphorus, potassium and other elements. Humus is a complex organic matter formed by animals and plants through long-term physical, chem...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a humic acid organic bio-compound fertilizer and its preparation process, which solves the problem that the existing humic acid bio-organic fertilizer has a high content of harmful bacteria, and the sterilization process is complicated, and the content of harmful bacteria is relatively high. The compound fertilizer will cause serious damage to the crops planted in the soil. At the same time, the duration of the existing humic acid fertilizer effect is not long enough, and the effect of dissolving phosphorus and potassium is not obvious enough and cannot last.
