Special set fertilizer for tobacco and preparation method thereof

Abstract

The invention discloses a special set fertilizer for tobacco and a preparation method thereof. The special set fertilizer for tobacco is prepared from the following components and raw materials in percentage by weight: 60% to 70% of composted organic material and 30% to 40% of inorganic fertilizer, wherein the composted organic material is prepared from 40% to 50% of dry mushroom residue, 25% to 33% of dry pig excrement, 8% to 17% of dry straw, 9% to 18% of dry oil cake, 0.2% to 0.5% of fermenting bacterial agent, and 0.18% to 1.05% of monoammonium phosphate through fermenting; the inorganic fertilizer is prepared from the following components and raw materials in percentage by mass: 5% to 8% of monoammonium phosphate, 13% to 17% of potassium nitrate, and 12% to 15% of potassium sulfate. The special set fertilizer for tobacco has the advantages that the nutrients can be effectively absorbed in a balance way in each stage of the tobacco; the labor intensity of a tobacco farmer is simplified, the fertilizer applying of the tobacco is balanced, and the like; in the tobacco production process, the labor intensity is decreased, the cost is reduced, the quality is improved, and the effect is enhanced.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a special package fertilizer for tobacco and a preparation method thereof. Background technique [0002] Tobacco is an important economic crop, which occupies a very important position in national taxation and local fiscal revenue. Tobacco cultivation is also one of the important ways for farmers in some areas to get rid of poverty and become rich. Before 1980, the cultivation of tobacco in my country was mainly based on farmyard manure and cake fertilizer, and chemical fertilizers were rarely used, because farmyard manure and cake fertilizer contained a large number of nutrients such as nitrogen, phosphorus, and potassium required by tobacco, and also contained calcium, magnesium, boron, zinc, etc. Medium and trace elements, the nutrients absorbed by tobacco plants are relatively balanced. However, the nutrient content and release of farmyard manure and cake fertilizer are not easy to...

AI Technical Summary

Problems solved by technology

However, with the continuous increase in the application of chemical fertilizers and the reduction in the use of traditional farmyard manure, problems such as compaction of the tobacco-planting soil, reduction in the number and population of effective microorganisms in the soil, and imbalance of nutrient elements have become more and more prominent, which has also caused the chemical composition of tobacco leaves to be uncoordinated, The yield and disease resistance are greatly reduced, and the quality of tobacco leaves is reduced
