Embodiment 1

[0066] ——The experimental site is Yunnan Academy of Tobacco Agricultural Sciences The experimental variety is Yunyan 87

[0067] A. Floating seedling cultivation: The sowing date of tobacco seedlings is February 22. After the tobacco seedlings are sown into the matrix planting holes, place the seedling raising floating tray 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.

[0068] B: Land preparation and ridging: shallow plowing and stubble removal in time after the previous crops are harvested, entropy accumulation in the crushed soil 25 days before transplanting, deep plowing and land preparation, and irrigation of the field 10 days before transplanting. According to the row spacing of 100cm, the ridge he...

Abstract

The invention discloses a cultivation method ensuring field growth time of fen-flavor tobacco leaves and belongs to the technical field of the tobacco plant cultivating technology. The method comprises the working procedures of float breeding, soil preparation, ridging, under-membrane transplanting, membrane covering period management, and field management. A seeding period is from the middle ten days of October to the middle ten days of December. A floating disk float breeding method is adopted. Hardening-seedling is conducted for 8-14 days before transplantation. Soil is broken, and moisture in the soil is stored. Soil is prepared, and a field is irrigated. Ridges are built up with 100-120cm row distances. The height of each ridge is 20-30cm. The width of the bottom of each ridge is 75-95cm. Base fertilizer is added at ridging time in a double-strip mode. A transplanting period is from the middle ten days of January to the last ten days of March. Caves are built up with 45-55cm plant distances. The width of each cave is 10-15cm. The depth of each cave is 15-20cm. 1-2kg root locating water is watered on each plant after transplantation. Land membrane is covered. Fertilize plants additionally for two times after transplantation. Seedlings are induced when tops of tobacco seedlings jack the membrane on the 15th-25th day. The field membrane is uncovered when the tobacco seedlings enter the middle flourishing growth period. Ridging, weeding, watering, tip pruning and branch removing are conducted timely. The method can effectively ensure the field growth time of tobacco leaves, improves the output and the quality of tobaccos, increases the accumulation of aroma substances, and strengthens the fragrance style of fen-flavor tobacco leaves.

Description

technical field [0001] The invention belongs to the technical field of tobacco plant cultivation, and in particular relates to a cultivation method capable of effectively ensuring the field growth time of fragrance type tobacco leaves. Background technique [0002] The growth time of flue-cured tobacco in the field varies with the variety and cultivation conditions of flue-cured tobacco, generally 100-130 days. In order to obtain high-quality and stable yield of tobacco leaves, corresponding cultivation technical measures must be taken according to the growth and development characteristics of tobacco plants at each growth stage in the field. Reasonable promotion and control and scientific management to promote the normal growth and development of tobacco plants and ensure the excellent appearance and intrinsic quality of tobacco leaves. First of all, the length of the hardening period has a very important impact on the growth and development of tobacco plants and the yield ...
