Compound fertilizer special for flue-cured tobacco

Abstract

The invention discloses a compound fertilizer special for flue-cured tobacco, which belongs to the field of fertilizers. The compound fertilizer comprises the following components in percentage by mass: 31.34-32.40 percent of organic substance, 64.46-65.34 percent of inorganic fertilizer and 2.93-3.88 percent of trace element, wherein the organic substance comprises four kinds of farm fertilizer,such as chicken manure, pig manure, cow manure and oil cake. The compound fertilizer is prepared by fermenting, drying and pulverizing treatment. The compound fertilizer which is suitable for the flue-cured tobacco variety is researched according to the fertilizer demanding rule of cigarette 103 in the flue-cured tobacco variety represented in the Luzhou cigarette area; on one hand, the tobacco leaf yield can be increased and the tobacco leaf quality is improved, the income is increased and the production investment can be reduced; on the other hand, the pollution of fertilizer loss to the environment can be reduced. After the organic and inorganic compound fertilizer is applied to the soil, beneficial microorganisms in the soil can be rapidly activated and bred, nutrient substances unabsorbed by the flue-cured tobacco are changed into absorbable nutrient substances, and the fertilizer effect is durable; meanwhile, the invention has the effects of improving soil ground temperature andsoil and increasing both production and income of the tobacco.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a special fertilizer for flue-cured tobacco. Background technique [0002] Flue-cured tobacco is extremely sensitive to fertilizers, and the type, amount and ratio of fertilization have a great impact on the yield and quality of tobacco leaves. At present, the difference between my country's tobacco leaf quality and the international high-quality tobacco leaf producing countries is largely related to the imbalance of fertilizer application. Traditional organic and inorganic fertilizer formulas are relatively simple in composition and nutrients, simply mixing several organic substances and inorganic fertilizers, and rarely considering the addition of trace elements, so they cannot meet the normal growth needs of flue-cured tobacco. [0003] At present, a large amount of inorganic fertilizers are still used on tobacco, such as tobacco-specific fertilizers, potassium nitrate and potassium sulfate, r...

AI Technical Summary

Problems solved by technology

The traditional organic and inorganic fertilizer formulas are relatively single in composition and nutrients. They simply mix several organic substances and inorganic fertilizers, and rarely consider adding trace elements, so they cannot meet the normal growth needs of flue-cured tobacco.

[0003] At present, a large amount of inorganic fertilizers are still used on tobacco, such as special fertilizers for tobacco, potassium nitrate and potassium sulfate, resulting in low organic matter content in the soil in the tobacco planting area, underdeveloped tobacco root system, thin leaves, light color of the tobacco leaves after roasting, and relatively flat aroma and taste, etc.

If used for a long time, it will cause soil compaction, soil salinization increase, tobacco yield and quality will be reduced, and it will bring non-point source pollution

Therefore, with the acceleration of the development of special tobacco leaf projects in various places, due to the different types of fertilizers required by different flue-cured tobacco varieties, it is difficult for ordinary tobacco-specific fertilizers to meet the needs of cigarette companies for the quality of tobacco leaves of different flue-cured tobacco varieties

[0004] China Tobacco 103 is a new variety of flue-cured tobacco selected and bred by China Tobacco Breeding Research (Northern) Center. At present, there is no use and report of fertilizers specifically for China Tobacco 103, and the existing common compound fertilizers cannot meet the needs of industrial enterprises for China Tobacco 103. High-quality characteristic tobacco leaves cannot be planted due to the requirement of quality
