Flue-cured tobacco cultivation method fitting in with light environment of Yunnan tobacco-growing area

Abstract

The invention discloses a flue-cured tobacco cultivation method fitting in with the light environment of the Yunnan tobacco-growing area and belongs to the technical field of tobacco plant cultivation. The flue-cured tobacco cultivation method comprises the following steps of float breeding, soil preparation and ridging, transplanting under film, management in film covering period and field management. The seeding time is from mid December to mid February, the float disc floating seedling method is adopted, and seeding hardening lasts for 8-14 days before transplanting; ridging is conducted after the soil is pulverized and moisture is stored, and inorganic fertilizer and cake fertilizer which is thoroughly decomposed are mixed to be applied to the field; the transplanting period is from mid March to mid April, the density of tobacco plants is 1000-12000 plant / mu, each tobacco plant is irrigated with 1.5-2.5kg root water after transplanting, and colored mulching film is covered; top dressing is conducted twice after transplanting, and seeding leading is conducted 15-25 days after the top of each tobacco seeding ejects the film; the mulching film is removed when the tobacco plants enter the mid of the vigorous growth period, earthing up, weeding and watering are conducted in time, and topping, leaf reserving and bifurcation removing are conducted. The flue-cured tobacco cultivation method can fitting in with the light environment of the Yunnan tobacco-growing area, the local light source can be utilized fully and reasonably, the quality of tobacco leaves can be improved, and the aroma style of the fen-flavor tobacco leaves is enhanced.

Description

technical field [0001] The invention belongs to the technical field of tobacco plant cultivation, and specifically relates to a flue-cured tobacco cultivation method that adapts to the characteristics of the light environment in Yunnan tobacco areas, rationally utilizes local light resources, and improves the quality of tobacco leaves. Background technique [0002] Light is an important factor affecting the growth and development of plants. It not only affects the photosynthesis of plants, but also acts on plants in the form of environmental signals. external environment. Tobacco is a kind of light-loving crop. It needs sufficient and suitable light in the process of growth and quality formation in the field, and the intensity, time and light quality of light will have a great impact on the internal quality of tobacco plants such as shape, growth and development, photosynthesis, and chemical composition. big impact. [0003] In terms of the growth and development of tobacc...

Problems solved by technology

However, in the later stage of field growth, the weather is more sunny and less rainy, and the temperature is low, which is not conducive to the accumulation of aroma substances in tobacco leaves and the increase of potassium content. This is also an important difference between the climate of Yunnan tobacco areas and high-quality tobacco areas at home and abroad.
