Carbonization straw organic fertilizer and preparation method thereof

Abstract

The invention discloses a carbonization straw organic fertilizer and a preparation method thereof. The carbonization straw organic fertilizer comprises the following raw materials by weight part: 4-7 parts of vermiculite powder, 5-8 parts of limestone powder, 2-4 parts of ammonium chloride, 10-15 parts of beer groove, 2-3 parts of EM inocula, 35-50 parts of livestock night soil, 20-25 parts of pond mud, 30-40 parts of crops straw, 10-15 parts of potassium phosphate, 20-25 parts of rock phosphate, 14-20 parts of ammonium bicarbonate, 13-18 parts of potassium permanganate, 4-5 parts of cross-linking agent and a proper amount of water. The livestock night soil uses microbe bacterium to ferment to obtain the decomposed products, the livestock night soil is taken as a basic substrate for the fertilizer, crude active carbon after charing straw and an inorganic nutrition component are added, fertilizer application amount is reduced, an inorganic chemical component can be fully used, loss and water / soil pollution can be avoided, a stone flour coating agent is coated, adhesion caking of the fertilizer is effectively prevented, a part of ammonium chloride is used for coating components, the coating layer can be porous, and the nutriment can be released.

Description

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