Special full-component biological organic fertilizer for tobaccos and preparation method of special full-component biological organic fertilizer

Abstract

The invention discloses a special full-component biological organic fertilizer for tobaccos and a preparation method of the special full-component biological organic fertilizer. The organic fertilizer is mainly prepared from the following raw materials in parts by weight: 26-38 parts of fermented rapeseed cakes, 18-22 parts of nitrogen fertilizers, 13-20 parts of phosphorus fertilizers, 16-22 parts of potassium fertilizers, 3-5 parts of humic acid, 3-5 parts of amino acid raw powder, 2-4 parts of secondary and trace nutrient elements, 1-3 parts of active silicon fertilizers, 1-3 parts of rhizoma phragmitis, 2-3 parts of clove, 0.5-2 parts of functional microorganisms and 0.5-1 part of nitrogen fertilizer synergists. The special full-component biological organic fertilizer for the tobaccos is complete in product nutrients, and can meet the nutrient elements needed for the growth of the tobaccos; components in a full-component biological organic fertilizer product cooperate with one other and achieve synergism; the full-component biological organic fertilizer is easily absorbed by crops; the yield and the quality of tobacco leaf can be obviously improved; the rhizosphere microenvironment of the plants can be improved; the resistance of the crops can be improved; meanwhile, the application of chemical fertilizers can also be reduced; the quality of a cultivated land can be improved.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a whole-element bio-organic fertilizer dedicated to tobacco and a preparation method thereof. Background technique [0002] Tobacco is an important economic crop in my country. At present, my country is the world's largest producer of tobacco leaves. The annual planting area is more than 18 million mu, accounting for about 1% of the total cultivated land in the country. It is mainly concentrated in Yunnan, Guizhou, Sichuan, Chongqing, Hunan, Jiangxi and other hills and mountains. Because tobacco has been planted in a predatory manner for a long time, neglecting crop rotation and stubble, continuous cropping all year round, and insufficient combination of land use and land cultivation, the soil in most tobacco areas has been seriously degraded. Adding to the fact that tobacco is currently moving from the north to the south, and the southern tobacco areas generally ...

Problems solved by technology

Tobacco has been planted in a predatory manner for a long time, ignoring crop rotation and stubble, continuous cropping all year round, and insufficient combination of land use and land cultivation, resulting in serious soil degradation in most tobacco areas

Adding to the fact that tobacco is currently moving from the north to the south, and the southern tobacco areas generally have shallow cultivated layers, plow bottoms and other barrier layers, and the soil fertility is low, resulting in large areas of land quality decline in the southern tobacco areas.

[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.
