Abstract

The invention relates to the technical filed of fertilizer for tobacco and discloses trace element fertilizer for the tobacco as well as a preparation method and an application method of the trace element fertilizer. The fertilizer comprises magnesium sulfate heptahydrate, zinc sulfate, boric acid, monopotassium phosphate and water, is used in a rosette stage and a vigorous growth stage of the tobacco and can improve the resistance of flue-cured tobacco remarkably, enhance the disease resistance, improve the tobacco aroma and increase the proportion of first-class and medium-class tobacco, thereby improving the quality of the tobacco. The fertilizer has the advantages of simple components, exact fertilizer efficiency, a little use amount, high absorptivity, low cost and high earnings and has great economic significance in agricultural development.

Description

technical field [0001] The invention belongs to the technical field of tobacco fertilizers, and in particular relates to a trace element fertilizer for tobacco and an application method thereof. Background technique [0002] Tobacco is an economic crop that takes into account both yield and quality. It requires not only a suitable yield, but also a coordinated chemical composition of tobacco leaves with good quality, so as to achieve the goals of sufficient aroma, pure quality, low irritation and low odor in tobacco leaves. The quality of tobacco leaves is not only restricted by quality factors, but also affected by climate, soil, cultivation and baking techniques, and the fertilization factor in cultivation measures has the most significant impact on the yield and quality of tobacco leaves. A balanced and harmonious supply of mineral nutrients is important for characteristic The formation of high-quality tobacco leaf quality is very important. [0003] In the process of th...
