Special bio-organic fertilizer for tobacco and preparation method for bio-organic fertilizer

Abstract

The present invention discloses special bio-organic fertilizer for tobacco and a preparation method for the bio-organic fertilizer, and relates to the technical field of agricultural fertilizer. The special bio-organic fertilizer is prepared by mixing the following materials in parts by weight: 1-3 parts of urea, 1-3 parts of diammonium phosphate, 2-6 parts of potassium sulfate, 40-60 parts of crop stalks, 5-15 parts of fermented rapeseed meal, 5-15 parts of soybean meal, 5-15 parts of sesame seed meal, 5-15 parts of humic acid, 0.5-1.5 parts of biological bacterium, and 0.5-1.5 parts of microelements. The special bio-organic fertilizer has the characteristics of being high in specificity and fertilizing value, and capable of greatly improving the quality and yield of tobacco leaves; under the condition of equal nutrients, by the application of the product, the yield of tobacco leaves is improved by about 10%, the quality of the tobacco leaves is improved by more than one grade, and the effect is very remarkable; the product can be applied to tobacco, and industrial crops of grain and oil crops, fruit trees, vegetables, tea leaves, and the like; during the application, the special bio-organic fertilizer is mainly taken as base fertilizer to be applied deeply, and can also be taken as additional fertilizer to broadcast or sprayed on leaves by adding water.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizers, in particular to a special bio-organic fertilizer for tobacco and a preparation method thereof. Background technique [0002] my country is the world's largest producer of tobacco leaves, with more than 1.4 million hectares of tobacco planted each year and an annual output of more than 1.7 million tons of tobacco leaves. Tobacco is an important economic crop in my country. [0003] Tobacco has high requirements on nutrients. At present, traditional planting methods are basically adopted, and the fertilizers applied are mainly chemical fertilizers or compound fertilizers, resulting in soil compaction, thin tobacco leaves, light color, low yield, and poor quality. The tobacco-specific fertilizers on the market are poorly targeted, have no scientific formula according to the characteristics of tobacco fertilizers, and have low high-grade organic matter content. After application, t...

Problems solved by technology

[0003] Tobacco has high requirements on nutrients. At present, traditional planting methods are basically adopted, and the fertilizers applied are mainly chemical fertilizers or compound fertilizers, resulting in soil compaction, thin tobacco leaves, light color, low yield, and poor quality. The special fertilizers for tobacco on the market are poorly targeted, and there is no scientific formula according to the characteristics of tobacco fertilizers, and the content of high-grade organic matter is low. After application, the effect of improving the thickness, color, yield and quality of tobacco leaves is not good.
