Method for improving tobacco quality by modest extension of vegetative growth period of flue-cured tobaccos

Abstract

The invention discloses a method for improving the tobacco quality by the modest extension of a vegetative growth period of flue-cured tobaccos. The method comprises the processes of primed pelleted seeds of flue-cured tobaccos, seeding, seedbed growing, transplanting, growth in field and the like, wherein the seeds germinate again before sowing the primed pelleted seeds of flue-cured tobaccos; the nutritional regulation is performed for the first time 10 days after transplanting in the field, the dosage is 5 kg per acre; the nutritional regulation is performed for the second time 35 days after transplanting in the field, the dosage is 10 kg per acre. The method is convenient for the flue-cured tobaccos to fully absorb nutrients in the vegetative growth period, is more conducive to accumulating dry matters of leaves, improving the chemical components, appearance quality and sensory evaluation of the flue-cured tobaccos and improving the quality of tobaccos by delaying the flower bud differentiation time of the flue-cured tobaccos, extending the vegetative growth period of the flue-cured tobaccos and shortening a reproductive growth period of the flue-cured tobaccos.

Description

technical field [0001] The invention relates to a method for improving the quality of tobacco leaves by moderately prolonging the vegetative growth period of flue-cured tobacco, and belongs to the technical fields of flue-cured tobacco cultivation technology and tobacco leaf quality regulation. Background technique [0002] Flue-cured tobacco is a special economic crop mainly harvesting vegetative organ leaves and high economic benefits. In the process of flue-cured tobacco production, it is necessary to promote the maximum growth and absorption of vegetative organs and leaves, and inhibit or block the growth and development of reproductive organs, flowers and seeds, so as to improve the quality of tobacco leaves and meet the needs of cigarette companies for the quality of raw tobacco leaves. In terms of improving the quality of tobacco leaves, technical measures such as improving fertilization formula, increasing application of trace element foliar fertilizer, increasing ap...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a method for improving the quality of tobacco leaves by moderately prolonging the vegetative growth period of flue-cured tobacco, which can prolong the vegetative growth period of flue-cured tobacco, shorten the reproductive growth period of flue-cured tobacco, and promote the nutrition of tobacco leaves without affecting the entire growth period of flue-cured tobacco. growth, improve the intrinsic quality of tobacco leaves to solve the problems of high cost and insufficient technology of existing measures
