Wheat straw biochar fertilizer capable of increasing yield and income and preparation method thereof

Abstract

The invention discloses a wheat straw biochar fertilizer capable of increasing yield and income and a preparation method thereof. The wheat straw biochar fertilizer is prepared from the following raw materials in parts by weight: 37-43 parts of corn cob granule, 22-26 parts of traditional Chinese medicine residue, 3-5 parts of sodium nitrate, 2-4 parts of sodium chloride, 3-4 parts of calcium bicarbonate, 28-32 parts of beanpod shell powder, 2-3 parts of disodium edetate, 110-130 parts of fresh Enteromorpha, 4-5 parts of composite microbial inoculant, 190-210 parts of wheat straw, 24-28 parts of fresh urine and a right amount of water. Abundant biomass, quick-acting nutrients, microbes and other components are added on the basis of the straw carbon powder; the quick-acting nutrients and biomass can provide long-term nutrient supply for crops under the combined actions; the biochar surface can be used as a habitat of the composite microbes, thereby being beneficial to growth of the microbial florae; and the carbon dioxide released by respiration can enhance the concentration of carbon dioxide near the crops, thereby promoting the photosynthesis of crops and achieving the effect of increasing the crop yield.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a wheat straw biochar fertilizer for increasing production and income 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 agr...

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.
