Flue-cured tobacco cultivation method resisting spring drought

Abstract

The invention relates to a flue-cured tobacco cultivation method resisting spring drought. The method comprises the steps that variety distribution is reasonably planned; ditching and ridging are carried out, and a two-row concave ridge which is 200-240cm in width and 20-25cm in height is implemented; for transplantation, seedlings are transplanted early in good time, transplantation is generally finished during the period from the end of March to the middle ten days of April, the method of a well cellar with the diameter of 8-9cm and the depth of 16-20cm is adopted, and a shovel is utilized for marking out a concave furrow which is 8-10cm in width and 2-3cm in depth on the ridge, so that the well cellar is dug easily, and water is prevented from being wasted; fertilizer is applied according to the equal nitrogen principle, and 30-50% of organic nitrogenous fertilizer is additionally applied to soil for the second time; film mulching is carried out, a film is uniformly compacted through soil in a line-shaped mode, and a gap between the surface of the soil and the film is 0.5-1cm. The method simple and easy to implement is adopted for carrying out flue-cured tobacco cultivation, harm to growth and development of flue-cured tobaccos due to the drought can be reduced, an effective yield increase way is provided for tobacco-growing areas suffering from the drought, the output value is increased, and the economic benefit is increased.

Description

technical field [0001] The invention relates to a spring drought-resistant cultivation method of flue-cured tobacco, which belongs to the field of flue-cured tobacco cultivation in agriculture and planting. Background technique [0002] Guizhou is the second largest tobacco-producing province in the country. The output of flue-cured tobacco accounts for about 1 / 6 of the country's total output. The output value of tobacco leaves accounts for more than 50% of the income of farmers in tobacco-growing areas, and the tax revenue of tobacco leaves accounts for 1 / 4 of the tax revenue of local governments in tobacco-growing areas. one or so. Therefore, the sustainable and stable development of tobacco production in Guizhou is related to the steady development of Guizhou's economy. However, due to the complex geographical environment of Guizhou and the typical karst landform, some tobacco areas are seriously affected by seasonal drought (spring drought), which hinders the developmen...

Problems solved by technology

[0003] At present, the only Chinese patent applications and documents retrieved on the drought-resistant cultivation technology of flue-cured tobacco are No. 201110203197.5 "Transplanting Method for Seedlings Transplanted in Tobacco Film-Mulched Well Cellars" and "Double-row Concave Ridge Full Growth Period Mulching and Water Conservation" published by Science and Technology Wind Magazine Application of Cultivation Techniques in Arid Tobacco Areas, these techniques are effective, but they cannot directly solve spring drought and related problems in some tobacco areas

For example, soil quality is mainly aimed at: double ridge cultivation, although it can help to collect field precipitation, but it cannot be stored in the soil, which still causes dryness and compaction of the soil in the plow layer; overgrown weeds in the plastic film: both of the above two technologies exist During the long period of prosperity, weeds grow wildly in the mulch, which creates an unfavorable situation of competing with flue-cured tobacco for nutrients
