Abstract

A release-controlled fertilizer of tobacco for promoting growth of tobacco leaves, increasing content of K and improving quality is proportionally prepared from KNO3, adhesive, (NH4)2SO4, K2SO4, (NH4)2HPO4, organic fertilizer and ordinary calcium perphosphate through mixing KNO3 with adhesive, granulating, and sequentially coating others one by one.

Description

technical field [0001] The invention relates to a tobacco fertilizer and its production method and application, in particular to a tobacco-specific controlled-release fertilizer and its production method and application. Background technique [0002] Using fertilizer to adjust the type, quantity and nutrient supply characteristics of soil nutrients is an important and effective measure to obtain the yield and quality of tobacco leaves. For a long time, people have achieved certain results in the research on tobacco planting soil and fertilization technology, especially a kind of special fertilizer for flue-cured tobacco designed and produced according to the law of flue-cured tobacco fertilization and the principle of balanced fertilization. However, among many tobacco-specific fertilizers of this kind, the controlled-release fertilizers for tobacco that use granulation, coating and other means to achieve effective control of fertilizer nutrient release, thereby achieving a ...
