Wheat straw biochar fertilizer capable of reducing greenhouse gas emission and preparation method thereof

Abstract

The invention discloses wheat straw biochar fertilizer capable of reducing greenhouse gas emission and a preparation method thereof. The wheat straw biochar fertilizer capable of reducing the greenhouse gas emission is prepared, by weight, by the following raw materials of 42-46 parts of bean pulp, 9-13 parts of zeolite powder, 8-10 parts of milk extract powder, 4-5 parts of copper sulfate, 3-4 parts of ferric chloride, 25-29 parts of weathered coal, 2-4 parts of ferric sulfate, 135-155 parts of fresh enteromorpha, 4-6 parts of compound microorganism bacterium agents, 270-290 parts of wheat straw, 28-30 parts of fresh urine and an adequate amount of water. According to the wheat straw biochar fertilizer capable of reducing the greenhouse gas emission and the preparation method thereof, the storage capacity of soil carbon can be increased after the biochar fertilizer is applied into soil, soil organic substances are increased, soil fertility is increased, degradation resistance is achieved simultaneously, storage time of carbon in the soil is prolonged, adsorption of carbon dioxide is improved through porosity, the greenhouse gas emission to the air is reduced, the wheat straw biochar fertilizer capable of reducing the greenhouse gas emission serves as a fertilizer source to ensure crop growth and reduces air environment pollution, and the wheat straw biochar fertilizer capable of reducing the greenhouse gas emission is green and recyclable ecotype carbon fertilizer.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a wheat straw biochar fertilizer for reducing greenhouse gas emissions and a preparation method thereof. Background technique [0002] Biochar is an organic substance rich in stable carbon obtained by oxygen-limited pyrolysis and carbonization of biomass. Biochar can not only effectively increase the organic carbon content in the soil, but also gradually improve soil fertility and water retention. Soil nutrient loss and other aspects also have good effects. [0003] As the proportion of my country's agricultural products exports continues to increase, agriculture's requirements for fertilizers and soil fertility will continue to upgrade. Therefore, the use of biochar fertilizers from the perspective of changes in the types of soil fertilizers and fertility improvements will have a significant impact on the adjustment of my country's agricultural structure and the export of ag...

Problems solved by technology

[0004] However, due to the light weight of biochar, it is in the form of powder, takes up a lot of space, and the cost of transportation and storage is high. In addition, there are difficulties such as inconvenient application and dust pollution in the process of farmland application, which limits the agricultural promotion and utilization of biochar.
