Embodiment 1
[0012] Take 41.5kg of decomposed oil, 5.8kg of monoammonium phosphate, 3.5kg of diammonium phosphate, 24.3kg of potassium sulfate, 13.4kg of potassium nitrate, 3.5kg of potassium chloride, 0.9kg of anhydrous borax, 0.7kg of zinc sulfate, and 0.5kg of magnesium sulfate , amino acid 1.5kg, potassium humate 4.4kg. The above-mentioned raw materials were mixed, then fully pulverized, and completely passed through a 1mm sieve to obtain the special organic-inorganic compound fertilizer 1 for Honghua Dajinyuan flue-cured tobacco varieties.
Embodiment 2
[0014] Take 40kg of decomposed oil, 4.8kg of monoammonium phosphate, 4.8kg of diammonium phosphate, 24kg of potassium sulfate, 14.7kg of potassium nitrate, 3.6kg of potassium chloride, 0.7kg of anhydrous borax, 0.6kg of zinc sulfate, 0.5kg of magnesium sulfate, amino acid 1.5kg, potassium humate 4.8kg. Mix the above-mentioned raw materials, then fully pulverize them, and completely pass through a 1mm sieve to obtain the special organic-inorganic compound fertilizer 2 for Honghua Dajinyuan flue-cured tobacco varieties.
Embodiment 3
[0016] Take 43kg of decomposed oily oil, 5.2kg of monoammonium phosphate, 4kg of diammonium phosphate, 24.5kg of potassium sulfate, 12.6kg of potassium nitrate, 2.8kg of potassium chloride, 0.7kg of anhydrous borax, 0.6kg of zinc sulfate, 0.5kg of magnesium sulfate, amino acid 1.4kg, potassium humate 4.7kg. The above-mentioned raw materials were mixed, then fully pulverized, and completely passed through a 1mm sieve to obtain the special organic-inorganic compound fertilizer 3 for Honghua Dajinyuan flue-cured tobacco varieties.

Abstract
The invention provides an organic and inorganic compound fertilizer specially used for Honghua Dajinyuan flue-cured tobacco and a preparation method of the fertilizer. The organic and inorganic compound fertilizer specially used for the Honghua Dajinyuan flue-cured tobacco is prepared according to fertility of tobacco-planting soil and fertilizer requirement law of the Honghua Dajinyuan flue-cured tobacco, has good water solubility and can better coordinate soil nutrient supply and improve resistance of the Honghua Dajinyuan flue-cured tobacco to'two black diseases' (namely black shank and black root rot), brown spot disease and the like after being applied; meanwhile, early growth and quick tillering in earlier stage as well as maturity and yellowing in later stage of the Honghua Dajinyuan flue-cured tobacco plant can be promoted; convenience is provided for tobacco farmers in a baking process, and quality of tobacco leaves is improved; the organic and inorganic compound fertilizer specially used for the Honghua Dajinyuan flue-cured tobacco can be simply used by the tobacco farmers, the amount of labour used by the farmers can be reduced, and the working efficiency can be improved.
Description
technical field [0001] The invention belongs to the field of fertilizer formulations for promoting the growth of flue-cured tobacco and improving the disease resistance of flue-cured tobacco, in particular to a special organic-inorganic compound fertilizer (containing nitrogen in two forms of organic and inorganic) and a preparation method thereof. Background technique [0002] Tobacco is a crop that pays equal attention to yield and quality, especially quality. Reasonable fertilization is the key to ensure the normal growth and development of flue-cured tobacco and achieve high quality and suitable production. In flue-cured tobacco production, great attention is paid to the rational application of fertilizers. Over the years, many special fertilizers for flue-cured tobacco have appeared in production, and achieved good results. Honghua Dajinyuan is a flue-cured tobacco variety with a very prominent fragrance style, but it is sensitive to nitrogen fertilizers, and diseases ...
