Problems solved by technology

Although foliar spraying of potassium sulfate or potassium dihydrogen phosphate has a certain effect on promoting the photosynthesis of tobacco plants, due to the characteristics of potassium sulfate or potassium dihydrogen phosphate and the absence of functional substances such as trace elements and rare earth elements, potassium sulfate Or Potassium Dihydrogen Phosphate is not very effective in enhancing photosynthesis

Abstract

The invention discloses a foliar fertilizer for enhancing photosynthesis of flue-cured tobacco and a preparation method for the foliar fertilizer. The foliar fertilizer comprises nutritive substances and functional substances, wherein the nutritive substances comprise 31-50 parts by weight of potassium sulfate and 31-56 parts of potassium dihydrogen phosphate, and the functional substances comprise 5-10 parts by weight of organic acid, 5-10 parts of solid organosilicone surfactant, 2-3 parts of minor elements, 0.1-0.9 part of medium elements and 0.1-0.9 part of chelated rare earth. The foliar fertilizer for enhancing the photosynthesis of the flue-cured tobacco and the preparation method for the foliar fertilizer, provided by the invention, have the aims that the chlorophyll content, light energy absorption efficiency and photosynthetic enzyme activity are further improved, thus, the photosynthesis of the flue-cured tobacco is enhanced from a plant physiology aspect, the accumulation of carbon nitrogen metabolism and secondary metabolism products of tobacco plants is promoted, and the improvement on hierarchic structure and quality of tobacco leaves is facilitated.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a foliar fertilizer for enhancing the photosynthesis of flue-cured tobacco and a preparation method thereof. Background technique [0002] The quality of flue-cured tobacco is mainly determined by the content of secondary metabolites such as total sugars, alkaloids, amino acids, pigments, etc. inside the tobacco leaves. The content of secondary metabolites in flue-cured tobacco is closely related to photosynthesis, which is closely related to phosphorus, potassium, various trace elements, and rare earth elements. Less, trace elements are almost not used, resulting in a decline in the net photosynthetic efficiency of the tobacco leaves in the late growth period, nitrogen in the tobacco plant cannot be metabolized, and the tobacco leaves cannot mature normally and yellow, which seriously affects the sales of tobacco leaves. [0003] In view of the decline in photos...
