Biochar-humic acid organic fertilizer

Abstract

The invention discloses biochar-humic acid organic fertilizer. The biochar-humic acid organic fertilizer is made of 550-650 kg of biochar, 320-380 kg of humic acid, 45-55 kg of alfalfa ad 55-65 kg of chitosan hydrolysates. The biochar is obtained through the steps of drying cotton straw, corn stalks or / and sweet potato seedlings, putting the cotton straw, the corn stalks or / and the sweet potato seedlings into a carbonization oven for carbonizing the cotton straw, the corn stalks or / and the sweet potato seedlings and then drying and smashing charcoal. The biochar-humic acid organic fertilizer is produced with the biochar and the humic acid as main raw materials, is a kind of bottom application type fertilizer and is applied at the initial stage of plant cultivation. The organic fertilizer is rich and comprehensive in nutrition, can provide nutrition needed by plant growth without adding other chemical fertilizer, can promote plant growth, is effective for crops, industrial crops, vegetables, fruit trees and the like, has obvious yield increase effect and has high application value.

Description

technical field [0001] The invention relates to an organic fertilizer prepared from biochar and humic acid. Background technique [0002] Most of the world-wide aquaculture and planting industries use chemical antibiotics, growth agents, pesticides, etc. to promote the growth of animals and plants, prevent plant epidemic diseases, etc. Although the effect is obvious, it often causes excessive agrochemical residues and environmental pollution. Adverse consequences also have a great impact on the quality of crops. In particular, excessive application of simple chemical fertilizers such as nitrogen fertilizers will intensify soil compaction and reduce soil fertility, making it difficult for the quality and nutrition of crop products to meet people's needs, let alone meet the requirements of green food, and cause serious environmental pollution. [0003] Humic acid is a kind of macromolecular natural organic weak acid. According to its molecular weight from small to large, it ...
