Embodiment Construction
[0015] The following in conjunction with specific embodiments is intended to further illustrate the present invention, rather than limit the present invention.
[0016] a) Nitrogen is an essential element for the growth of tobacco leaves and one of the decisive indicators of quality. Excessive nitrogen application will cause the nitrogen and nicotine content in tobacco leaves to exceed the standard, and the loss of nitrogen will bring the risk of pollution to the environment. Therefore, control the amount of nitrogen fertilizer , improving nitrogen use efficiency is an important issue to be solved in tobacco fertilization. The present invention starts from the way of nitrogen utilization and loss, selects various urease inhibitors and nitrification inhibitors on the market and conducts field experiments in combination, comprehensively produces cost, tobacco yield and quality indicators, screens out the urease inhibitor as quinhydrone, The nitrification inhibitor is dicyandiami...

Abstract
The invention relates to a special additional fertilizer for tobacco with the function of improving the effect of nitrogen fertilizer and a use method thereof. For the problems that the content of nicotine and total content is commonly overhigh in the current tobacco, by combination with the requirement characteristic to the nutrient elements during the growth of the tobacco, a special additional fertilizer for growth of the tobacco with the functions of improving the effect of the nitrogen fertilizer, reducing the used amount of the nitrogen fertilizer and sufficient, reasonable and high-efficiency nutrients is prepared. The special additional fertilizer specifically comprises the following components in percentage by weight: 33.5% of agricultural potassium nitrate, 12% of 55% powdery monoammonium phosphate, 28.5% of agricultural potassium sulfate, 13%-16% of agricultural ammonium sulfate, 9.5%-12.5% of sepiolite, 0.5% of nitrogen fertilizer synergist (wherein 6% of quinhydrone and 94% of dicyandiamide), and all the components are granulated by an amino-acid method. The special additional fertilizer has the advantages that the growth of tobacco leaves can be promoted, the yield and production value of the tobacco are improved, the internal and external quality of the tobacco leaves is improved, the economic benefit of tobacco growers can be improved and the application prospect is good in tobacco production.
Description
technical field [0001] The invention relates to a special topdressing fertilizer for tobacco with improved nitrogen fertilizer efficiency and its application method, in particular to rationally selecting the topdressing nutrient element fertilizer required for tobacco growth according to the characteristics of the demand for nutrients in the growth period of tobacco, combined with the use of nitrogen fertilizer synergists , formulated as a high-efficiency and high-quality tobacco-specific topdressing fertilizer and its application method, which have the effects of promoting tobacco growth, improving tobacco leaf yield, tobacco leaf quality, and the like. Background technique [0002] Tobacco is one of the main economic crops in my country. Nitrogen is an important component of nicotine. Nitrogen application has a greater effect on the increase of nicotine content than other nutrients. Therefore, nitrogen is the most important element affecting the growth and development of to...
