A method for cultivating and harvesting tobacco leaves

Abstract

The invention discloses a tobacco leaf culturing and harvesting method. The method includes the steps that in the threshing stage, the number of leaves of tobacco is controlled in the range of from 12 pieces to 14 pieces; in the harvesting stage, the tobacco leaves are harvested three times. By means of the tobacco leaf culturing and harvesting method, the number of the effective leaves of the tobacco is controlled to range from 12 pieces to 14 pieces, the harvesting times are reduced to 3 times from 6-7 times, irrigation and tobacco fertilization are conducted in a matched mode before harvesting, the operation is simple and easy to master, the harvesting manpower cost is reduced greatly, the harvesting interval time is prolonged, the tobacco maturing time in the field is prolonged, the defects that the upper portion of the tobacco is thicker, and the texture structure is stiff are overcome, the situations that in a traditional harvesting mode, the tobacco is unfertilized, farmer and operators are inaccurate in operation, and the insufficient harvest maturity is caused are changed, the level structure of the baked tobacco is improved, and the quality level of the baked tobacco is increased, the comprehensive benefits of tobacco planting are promoted for the farmers, and the requirements for tobacco raw materials of the cigarette industry are well met; furthermore, the fertilization amount is reduced, so that the input cost of fertilizer is reduced for the farmers, and the pollution to the environment is reduced.

Description

technical field [0001] The invention relates to the field of tobacco leaf planting, in particular to a cultivation and harvesting method capable of improving the hierarchical structure of tobacco leaves. Background technique [0002] With the steady advancement of the strategy of optimizing the grade structure of tobacco leaf production, cigarette brands have put forward higher quality and structure requirements for tobacco raw materials. "Tobacco leaves are not picked well, and even immortals are difficult to roast", which fully demonstrates the important role of mature harvesting of tobacco leaves in improving the quality of roasting. [0003] At present, in the production of tobacco leaves, the number of leaves per plant is 16-18, and harvesting is carried out 6-7 times. There are generally too many leaves and harvesting times, the time for tobacco leaves to mature in the field is not enough, and harvesters do not have a good grasp of maturity. Accuracy, harvesting matur...

Problems solved by technology

[0003] At present, in the production of tobacco leaves, the number of leaves per plant is 16-18, and harvesting is carried out 6-7 times. There are generally too many leaves and harvesting times, the time for tobacco leaves to mature in the field is not enough, and harvesters do not have a good grasp of maturity. Accuracy, harvesting maturity does not meet the technical standards, harvesting and labor costs are too high, resulting in the proportion of low-grade tobacco is too large, the proportion of high-grade tobacco is not high, and the grade structure and quality of tobacco leaves are low, which cannot meet the needs of the cigarette industry. Enterprise raw material demand, resulting in supply and demand contradictions
