Special organic fertilizer for flue-cured tobacco and preparation method thereof

Abstract

The invention discloses a special organic fertilizer for flue-cured tobacco and a preparation method thereof. The special organic fertilizer comprises the following raw material components: cattle dung, sheep manure, mushroom dregs, humic acid and a fermentation inoculant. The preparation method comprises the steps of: mounting an aeration pipeline in a fermentation field before fermentation; mixing the cow dung, the sheep manure and the mushroom dregs according to a preset proportion, and stacking the mixture on the aeration pipeline; adjusting the moisture of the mixture, and stacking the mixture into a trapezoidal strip stack; paving a nano-film, and compacting the edge of the nano-film until no air leaks; and after fermentation is completed, adding humic acid and well mixing, and carrying out drying and cooling to obtain the special organic fertilizer for flue-cured tobacco. The special organic fertilizer can meet the requirement of flue-cured tobacco for the proportion of nutrients. Various bioactive substances in the organic fertilizer can improve the physical and chemical properties of soil, adjust the pH value of the soil, increase the pH value of the acidified soil by 20%-25%, enhance the buffering capacity and water and fertilizer retention capacity of the soil and increase the fertility of the soil by 10%-15%. Meanwhile, the effectiveness of the soil nutrients is improved, the absorption of flue-cured tobacco on soil nutrients and the growth and development of flue-cured tobacco roots are promoted, and the yield and quality of flue-cured tobacco are directly improved.

Description

technical field [0001] The invention belongs to the field of agricultural fertilizers, and relates to agricultural organic fertilizers, in particular to special organic fertilizers for flue-cured tobacco. Background technique [0002] As an important part of the earth's surface system, soil functions in the interaction process with other environmental factors, including water cycle function, nutrient cycle function, animal habitat function and crop production function, etc., which have basic and important functions in various fields. effect. [0003] Flue-cured tobacco is an important economic crop in my country, and the tobacco industry also occupies a very important position in the national economy. It is an important basic raw material for the production of cigarette industrial enterprises and has made great contributions to the construction of the country. The significance of stabilizing and developing high-quality tobacco leaves in agricultural production is very import...
