Abstract

The invention discloses biochar fertilizer with the effect of balancing fertilizer-water distribution. The biochar fertilizer is prepared from 60-80 parts by weight of biochar, 20-40 parts by weight of composite fertilizer, 10-20 parts by weight of a broth and 15-25 parts by weight of additives. The biochar fertilizer utilizes crop straws as raw material components. The straw raw materials have a low cost and are easily available. Through dehydration and deoxygenation treatment and high temperature charring crushing, biochar powder is obtained. The biochar fertilizer has good charring effects and char content of 25% or more. A straw charring rate is high, a char fertilizer yield is high, use effects are good, and the biochar fertilizer can passivate soil heavy metals and improve soil microbe vitality. The biochar fertilizer has a large specific surface area, improves soil organic matter content, can be used as low cost non-chemical fertilizer and guarantees yields in organic agriculture and green agriculture. The preparation method of the biochar fertilizer has simple processes, is controllable and can be implemented easily.

Description

technical field [0001] The invention relates to the fields of high-value comprehensive utilization of biomass resources and environmental pollution control, in particular to a biochar fertilizer that balances the distribution of fertilizer and water. Background technique [0002] No matter in the fields of food crops or commercial crops, fertilization has been used for a long time to improve crop yield and quality. From the earliest application of farm organic fertilizers to the application of inorganic fertilizers, and then to the application of organic-inorganic compound fertilizers. Fertilizer type, fertilization amount and ratio have a great impact on the yield and quality of food crops or economic crops. Although traditional fertilizers, especially organic-inorganic compound fertilizers, have played a good role in increasing crop yields. However, traditional fertilizers have an unreasonable ratio of ingredients and nutrients, which can hardly restore soil fertility, i...
