Carbonization straw microbe fertilizer and preparation method thereof

Abstract

The invention discloses a carbonization straw microbe fertilizer and a preparation method thereof. The carbonization straw microbe fertilizer comprises the following raw materials by weight part: 20-30 parts of wheat straw, 25-40 parts of rape straw, 10-14 parts of soybean straw, 5-10 parts of laterite, 1-2 parts of urea, 3-5 parts of beneficial microbe bacterial classification, 2-4 parts of polyvinyl alcohol, 6-10 parts of starch, 20-30 parts of kaolin, 10-15 parts of kali, 20-28 parts of ammonium carbonate, 16-22 parts of calcium-magnesia phosphate fertilizer, 6-10 parts of potassium nitrate, 4-5 parts of cross-linking agent and a proper amount of water. According to the invention, the microbe bacterial classification is embedded by polyvinyl alcohol and starch, and is mixed with straw charing products and basic nutriments required by vegetation to prepare the fertilizer, straw is charred to obtain the crude active carbon component, the carbonization straw has active carbon multiple function and has slow release efficacy of an inorganic nutrition element, the carbonization straw and the microbe bacterial classification are used for the fertilizer, so that fertilizer utilization rate is increased, absorption is promoted, and environment pollution is reduced.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a carbonized straw microbial 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 differen...

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
