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.

Abstract

The invention discloses a wheat straw biochar fertilizer with a drought resistant function and a preparation method thereof. The wheat straw biochar fertilizer is prepared from the following raw materials by weight: 22-25 parts of peat, 8-10 parts of guar gum powder, 4-7 parts of calcium chloride, 13-17 parts of urea, 26-28 parts of banana peel powder, 40-45 parts of millet bran, 9-11 parts of monoammonium phosphate, 125-135 parts of fresh enteromorpha, 4-6 parts of composite microbial agent, 270-290 parts of wheat straw, 25-28 parts of fresh urine and a proper amount of water. The biochar fertilizer has easily available abundant raw material sources has comprehensive nutrients and can provide long-term nutrition support for crop growth; the added guar gum powder, peat and biochar from straw pyrolysis can absorb water through macrovoids contained therein, and loss of the absorbed water can be prevented due to the stickiness, and thereby the water is locked in a fertilizing layer; in addition requirements of crops for water and fertilizer are met, and the biochar fertilizer has a good application prospect in an arid region.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a wheat straw biochar fertilizer with drought resistance function 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 agricul...
