Organic and inorganic compound fertilizer special for tobaccos

Abstract

The invention discloses an organic and inorganic compound fertilizer. By weight percentage content, the organic and inorganic compound fertilizer is prepared by rotten straws, rotten tobaccos, cake fertilizers, amino acid, potassium nitrate, potassium sulfate, ammonium dihydrogen phosphate, ammonium bicarbonate, urea, phosphatic fertilizers, ammonium molybdate, sodium borate or boracic acid, zinc sulfate and magnesium sulfate. The prepared organic and inorganic compound fertilizer contains components of organic matters, humus, amino acid, phosphorus pentoxide (P2O5), potassium oxide, nicotine, soluble total sugar and the like, and therefore the organic and inorganic compound fertilizer is led to have the advantages of promoting tobacco seedlings to survive, improving soil physical and chemical characteristics, improving nutrient balanced absorption ability, improving fertilizer use ratio, promoting tobacco plant root systems to grow, improving disease resistance and drought resistance of tobacco plants, improving tobacco leaf quality and the like. The raw materials of the organic and inorganic compound fertilizer adopt a large number of waste straws and tobacco waste materials, so that the waste straws and the tobacco waste materials are reused, and waste is changed to wealth. Therefore, the organic and inorganic compound fertilizer has remarkable economic benefit and social benefit.

Description

technical field [0001] The invention relates to a compound fertilizer for plants, in particular to a special organic-inorganic compound fertilizer for tobacco. Background technique [0002] The extensive popularization and application of balanced fertilization technology in the tobacco industry has greatly promoted the improvement of the yield and quality of tobacco leaves. However, most of the current balanced fertilization techniques only focus on balancing the nutrition of tobacco plants from the perspective of chemical fertilizer application, but ignore the adverse effects of long-term chemical fertilizer application, less or no organic fertilizer application on the tobacco planting soil environment. Coupled with continuous cropping, excessive cropping and lack of attention to soil improvement in tobacco fields, the soil permeability becomes poor during the tobacco leaf growing season, the humus content decreases, the soil is compacted, the soil environment for tobacco p...

AI Technical Summary

Problems solved by technology

At present, the use of organic fertilizers and inorganic compound fertilizers in tobacco cultivation is often separated, and the effective nutrients and release patterns of different organic fertilizers are quite different, resulting in the inability to achieve precise fertilization in tobacco leaf production. At the same time, the separate use of organic fertilizers and inorganic fertilizers will increase The amount of labor required for fertilization increases the labor cost of tobacco leaf production

The organic fertilizers currently used in tobacco are mainly cake fertilizers, fermented livestock and poultry manure, and crop straws. Due to the lack of standards for the degree of fermentation and the release rate of effective nutrients, the application effect of fertilizers is poor.

In recent years, some production areas have begun to plant organic tobacco leaves. The fertilization is all organic fertilizer. The fertilization per mu is generally more than 800kg, and some production areas even use 1500kg. The decline is more serious, and the yield per mu is generally lower than 125kg

At the same time, some tobacco leaf producing areas in my country have started to use organic-inorganic compound fertilizers. However, since most organic-inorganic compound fertilizers are currently aime...
