Embodiment 1

[0071] ——The experiment site is Huanxi Base of Fujian Tobacco Agricultural Science Research Institute

[0072] The experimental variety is Cuibi No.1.

[0073] A. Floating seedling cultivation: The sowing period of tobacco seedlings is mid-November. After the seeds of tobacco seedlings are sown into the matrix planting holes, place the floating tray for seedling cultivation on the surface of the nutrient bed pool, and cut the leaves when the tobacco seedlings are 6 cm high, twice before and after. Cut off water and control fertilizer before transplanting, harden the seedlings for 8 days, let the tobacco seedlings absorb enough water and fertilizer, and prepare for transplanting after 2 days.

[0074] B. Soil preparation and ridging: After the previous crops are harvested, shallow plowing and stubble removal in time, crush the corn stalks into small pieces of about 4cm, spread them back to the field after incomplete burning, and accumulate entropy in the crushed soil 25 days be...

[0079] ——The experiment site is the research and base of Yunnan Academy of Tobacco Agricultural Sciences

[0080] The experimental variety is Yunyan 87.

[0081] A. Floating seedling cultivation: The sowing period of tobacco seedlings is mid-February. After the tobacco seedlings are sown into the matrix planting hole, place the floating tray for seedling cultivation on the surface of the nutrient bed pool, and cut the leaves when the tobacco seedlings are 7 cm high, 3 times before and after. Cut off water and control fertilizer before transplanting, harden the seedlings for 14 days, let the tobacco seedlings absorb enough water and fertilizer, and prepare for transplanting after 3 days.

[0082] B. Land preparation and ridging: Shallow plowing and stubble removal in time after the previous crops are harvested, crush the wheat straw into small pieces of about 6cm, spread it back to the field after incomplete burning, and accumulate entropy in the crushed soil 35 days before tra...

Embodiment 3

[0087] ——Mengxian Township, Ning'er County, Pu'er City

[0088] The experimental variety is Yunyan 87.

[0089] A. Floating seedling cultivation: The sowing period of tobacco seedlings is late February. After the seeds of tobacco seedlings are sown into the matrix planting holes, place the floating tray for seedling cultivation on the surface of the nutrient bed pool, and cut the leaves when the tobacco seedlings are 6.5 cm high, twice before and after. Cut off water and control fertilizer before transplanting, harden the seedlings for 10 days, let the tobacco seedlings absorb enough water and fertilizer, and prepare for transplanting after 3 days.

[0090] B. Land preparation and ridging: Shallow plowing and stubble removal in time after the previous crops are harvested, crush the rice stalks into small pieces of about 5cm, spread them back to the field after incomplete burning, and accumulate entropy in the crushed soil 30 days before transplanting, deep plowing and land pre...

Abstract

The invention discloses a flue-cured tobacco cultivation method fitting in with the geographical characteristics of a fen-flavor tobacco producing 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 March, the float disc floating seeding method is adopted, seeding hardening lasts for 8-14 days before transplanting; straws return the field, ridging is conducted after the soil is pulverized and moisture is stored, the soil is prepared and the filed is irrigated, and cake fertilizer and farmyard manure which are thoroughly decomposed are mixed to be used as base fertilizer and then applied to the field; the transplanting period is from mid March to mid April, each tobacco plant is irrigated with 1-2kg root water after punch transplanting, and mulching film is covered; nitrogen fertilizer, phosphorus fertilizer and potassium fertilizer are evenly mixed and then applied to the field 7-9 days and 15-25 days after transplanting, and seeding leading is conducted when the top of each tobacco seedling ejects the film 15-25 days after the transplanting; the mulching film is removed when the tobacco plants enter the mid of vigorous growth period 30-40 days after transplanting, earthing-up, weeding and watering are conducted in time, topping, and leaf reserving and bifurcation removing are conducted. Through the flue-cured tobacco cultivation method fitting in with the geographical characteristics of the fen-flavor tobacco producing area, the geological soil characteristics of the fen-flavor tobacco-growing area are fully and reasonably utilized, the yield and the quality of tobacco leaves are 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 in particular relates to a method for cultivating flue-cured tobacco adapted to the geological characteristics of a fragrance-type tobacco leaf production area, rationally utilizing local soil resources, and improving the quality of tobacco leaves. Background technique [0002] Soil is the material basis for tobacco growth. The ecological conditions of the soil are closely related to the quality of tobacco leaves. Within a certain range, the ecological conditions of the soil have great influence on the field appearance and growth of tobacco plants, the output value, chemical composition, aroma substance content and tobacco leaf evaluation of tobacco leaves. The impact of suction quality is greater than the impact of variety. The types of soil-forming parent rocks in the fragrance-type tobacco area in southern my country mainly include clastic sedimentary rocks, acidic magmat...
