Example Embodiment

[0078] Example 1: Preparation process of special slow-release fertilizer for tobacco with biomass granular carbon as matrix

[0079] Follow the steps below to mix in weight ratio or weight percentage:

[0080] (1) Take 46% nitrogen (N) large granular urea, 80 mesh biomass granular carbon particles, mix them at a ratio of 59.2%, 40.8%, and use a disc granulator (fertilizer with heating function). Commonly used machinery in the preparation process) for coating to produce elemental slow-release nitrogen fertilizer with nitrogen (N) content of 27.23%.

[0081] (2) Take diammonium phosphate powder with nitrogen (N) content of 18% and effective phosphorus (P2O5) content of 46%, biomass granular carbon particles of 80 mesh and binder, according to 70.5%, 23.1% Mix it with 6.4%, and use KP-300 type organic fertilizer granulator for pressure granulation to produce a nitrogen-phosphorus compound fertilizer with a nitrogen (N) content of 12.69% and an effective phosphorus (P2O5) content o...

Abstract

The invention discloses a special slow release fertilizer for tobacco by using biomass granular carbon as a matrix and a preparation method thereof. Granular carbon prepared from agricultural wastes such as corn cobs, peanut shells, rice hulls, edible fungi matrix and the like are used as a matrix material; and based on the micro-pores and strong adsorption capability of the matrix material, the granular biomass carbon-based special slow release fertilizer for the tobacco is prepared by compounding the matrix material and nitrogen, phosphorus, potassium and other nutritional elements required by growth and development of the tobacco. The biomass granular carbon is black biomass granular carbon granules formed after the agricultural waste biomass is incompletely burnt under the low-oxygen condition, has multiple properties similar to soil humus and strong adsorption and nutrient and moisture holding capabilities, can stimulate growth of crops, and has good slow release performance on nitrogen, phosphorus and potassium; when the prepared slow release fertilizer is applied at one time, the requirements of the tobacco for nutrients in the whole growth period can be effectively met; and the slow release fertilizer has the characteristics of increasing soil fertility, improving the structure of soil, realizing high efficiency and environment friendliness and the like, and is beneficial to large-scale popularization and application in the production of the tobacco.

Description

[0001] technical field [0002] The invention belongs to the technical field of agricultural fertilizer production, and in particular relates to a tobacco-specific slow-release fertilizer with biomass granular charcoal as a matrix and a preparation method thereof. Background technique [0003] Tobacco is a raw material crop for the cigarette industry that is harvested from tobacco leaves. Reasonable fertilization is the key to the quality of tobacco leaves. In tobacco fertilization, the application rate of nitrogen fertilizer is very important. Tobacco is very sensitive to nitrogen. When the nitrogen content of the leaves exceeds 1%, it will cause poor combustion of the leaves, and flameout will occur in severe cases. Therefore, the production of high-quality tobacco leaves has very strict requirements on the amount of nitrogen fertilizer applied. Too little or too much will greatly affect the yield and quality of tobacco leaves. If there is less nitrogen application, the ...
