Rough-wrought charing bagasse fertilizer and preparation method thereof

Abstract

The invention discloses a rough-wrought charing bagasse fertilizer and a preparation method thereof. The rough-wrought charing bagasse fertilizer comprises the following raw materials by weight part: 30-50 parts of bagasse, 8-15 parts of wheat straw, 5-10 parts of dolomite powder, 1-2 parts of sodium bicarbonate, 20-30 parts of peat soil, 10-15 parts of decay leaf, 10-15 parts of 1mol / L hydrochloric acid solution, 15-20 parts of potassium nitrate, 14-18 parts of ammonium bicarbonate, 15-18 parts of calcium-magnesia phosphate fertilizer, 7-9 parts of calcium ammonium nitrate, 10-14 parts of urea, 4-5 parts of cross-linking agent and a proper amount of water. The rough-wrought charing bagasse fertilizer has the advantages of treatment of charing particle and selection of a coating agent, the charing particles select bagasse with high cellulose amount as a material, high temperature sealing and charing are carried out, dilute hydrochloric acid is used for immersing and washing to obtain a porous active carbon structure, dilute hydrochloric acid and a pulvis chemical fertilizer are tightly mixed, slow release effect is good, the coating agent is prepared by stone flour can provide a structural framework, the added sodium bicarbonate can be decomposed after being heated to leave the micropores, and water absorption and cracking are convenient.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a crude carbonized bagasse fertilizer and a preparation method thereof. Background technique [0002] Farmers have to burn straws in order to seize the farming season. The pollution of burning straws has affected the sustainable development of China's agriculture and national economy, and has become a serious social and economic problem and a hidden danger of traffic accidents. Straw carbonization is a process in which the straw is dried or sun-dried and crushed, and then in the charcoal equipment, the loose straw is made into charcoal through drying, carbonization, cooling and other processes. Since dry distillation is the core process of straw carbonization, some people use straw dry distillation to refer to straw carbonization. The charcoal produced by straw carbonization can be called straw charcoal or straw charcoal. Because straw carbonization is different ...

Problems solved by technology

[0004] Compound fertilizer can provide most of the nutrients for plant growth. It is produced with N, P, and K as the basic three elements mixed with stone powder or organic fermentation products as the basic base material. It is widely used in the cultivation of various crops and is indispensable. As agriculture tends to be more and more industrialized, the abuse and unreasonable use of fertilizers not only pollute the environment, but also cause unnecessary waste of resources, which violates the concept of sustainable development
