Problems solved by technology

The existing cultivation technology schemes in the Changsha Tobacco Area are either too high in planting density, causing mutual shading of plants; or too small in planting density, resulting in reduced production capacity and mostly direct sunlight on the ground, resulting in waste
It cannot actually meet the maximum utilization of light energy by the tobacco in the field, and does not make the growth and development of the tobacco and the quality of the product reach the best, and the quality of the tobacco leaves after curing is the best

Abstract

The invention relates to the technical field of tobacco leaf cultivation, and particularly relates to a cultivation method for improving the tobacco light energy utilization rate in Changsha tobacco area. The method comprises the steps of tobacco field preparation, ridging and grooving, watering, field planting, fertilizing, soil covering and film covering, threshing and the like; according to the method, G80 serves as the material, and the field experiment is carried out in Liuyang City, Hunan Province. On the optimization conditions that the nitrogen application rate is 12 kg / mu, the planting density is 1,300 plants / mu, and the number of remaining leaves is 16, the chlorophyll content, agronomic traits, group light transmittance and chemical composition of the tobacco leaves are better, so that tobacco plant development is moderate. Although the yield per mu of the tobacco leaves is decreased after roasting, the proportion of superior tobacco, average price per kilogram and per mu yield are obviously improved.

Description

technical field [0001] The invention relates to the technical field of tobacco leaf cultivation, and in particular relates to a cultivation method for improving the utilization rate of light energy of tobacco in Changsha Tobacco Area. Background technique [0002] Luzhou-flavored tobacco leaves are the core raw material of Chinese-style cigarettes in my country. Luzhou-flavored tobacco leaves in Changsha City are important supporting raw materials for high-end brands such as Hunan China Tobacco "Baisha" and Zhejiang China Tobacco "Liqun". It plays an irreplaceable role in the construction of high-end cigarette brands. The existing cultivation technology schemes in the Changsha Tobacco Area are either too high in planting density, causing mutual shading of plants; or too small in planting density, reducing production capacity and mostly direct sunlight on the ground, resulting in waste. It cannot actually meet the maximum utilization of light energy by the tobacco in the fiel...
