Compound fertilizer specially used for tobacco and method for producing same

Abstract

The invention relates to a compound fertilizer specially used for tobacco and a method for producing same. The compound fertilizer comprises the following components in percentage by weight: 19% of ammonium sulfate, 29% of potassium sulfate, 34% of ammonium dihydrogen phosphate, 0.6% of trace elements such as boron and 17.4% of additive. The method comprises the steps of independently crushing each component, fully and uniformly mixing the crushed fine powders, feeding into a granulation tower for granulation at the granularity diameter of 1-3mm, screening, testing and packaging according to the actual weight to produce the product. The compound fertilizer has the advantages that: the proportioning is scientific, the need of nutrition of tobacco in the whole growth process can be met, and the disease and insect resistance ability is strong; the process is simple, and the production cost of the fertilizer can be saved by extruding into grains through the mixing method; the application is convenient, one application can be enough, the fertilizer is beneficial for absorption of crops, and the modern agricultural needs oon labor and time conservation can be met; and the fertilizer is efficient and environment-friendly, the soil fertility can be improved for long time use and pollution is avoided, the tobacco yield can be increased by 15% after adopting the compound fertilizer specially used for tobacco, and the quality of the tobacco can be improved as well.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a special compound fertilizer for tobacco and a production method thereof. Background technique [0002] Tobacco is an important economic crop. Smoking is an indispensable part of the cultural life of hundreds of millions of smokers, and it is also an important source of income for the state and local taxes, and is highly valued by relevant departments. In 1984, China established the State Tobacco Monopoly Administration to unify the leadership and comprehensively manage the production and sales of the tobacco industry. Tobacco leaf production adheres to the policy of "planned planting, high-quality and suitable production, focusing on quality, persisting in reform, and improving efficiency", and vigorously promotes the scientific tobacco planting measures of "regionalization, improved varieties, and standardization", which has made great progress in China's tobacco production. Tobacco leaves ar...

Problems solved by technology

[0003] In recent years, the output per mu of tobacco has been continuously increasing, but the common problem is that the input cost is high, the output benefit is low, and the income of farmers cannot be increased. The direct reason is that tobacco production requires a large amount of fertilizer and high input cost, resulting in high yield of tobacco production. Not efficient, increasing production without increasing income

In addition, simple nitrogen fertilizers such as ammonium bicarbonate and urea are still used in tobacco planting. Long-term use will cause insufficient phosphorus and potassium fertilizers, and cannot effectively supplement the necessary trace elements required for tobacco growth.

Simple nitrogen fertilizers such as ordinary ammonium bicarbonate and urea release nutrients quickly, have short fertilizer effects, are not easily absorbed by crops, and cannot guarantee the nutrient supply in the middle and late stages of tobacco growth.

If more than two times of fertilization, the labor investment is huge, and the cost of money and effort cannot meet the needs of farmers' friends.
