Abstract

The invention provides a flue-cured tobacco cultivation method. The method comprises the following steps: firstly selecting flue-cured tobacco planting base land, ridging and applying a base fertilizer to the flue-cured tobacco planting base land, and water after applying the fertilizer so that the fertilizer is wet; selecting the date with the preference temperature and transplanting the seedlings, wherein the transplanting density is that the line spacing is 110-120 cm and the row spacing is 50 cm; applying the additional fertilizer to the transplanted seedlings, and covering by using a mulch film according to the local climate, film-uncovering after 30-35 days of transplanting; carrying out the thin intertillage treatment in the seedling stage, the root extending stage and the rosette stage, after 25-35 days of transplanting the seedlings, and carrying out the ridging treatment after the flue-cured tobacco seedlings grow 13-14 leaves; and topping and cutting branches, and then harvesting after the seedlings are grown. The method is used for promoting the early growing and quick sprouting after transplanting the seedlings, the internal chemical components of the tobacco leaves are more coordinated, the quality of the whole tobacco leaves is improved, and the economic benefit of the tobacco is improved.

Description

technical field [0001] The invention belongs to the technical field of flue-cured tobacco cultivation, and in particular relates to a method for cultivating flue-cured tobacco suitable for tobacco areas in southern my country. Background technique [0002] Tobacco (Nicotiana tabacum) is an annual herbaceous plant of the genus Nicotiana in the family Solanaceae. Roots can synthesize nicotine. The stem is erect, and each leaf axil has axillary buds, which can germinate into branches. The leaves are alternate and arranged in a spiral shape. The planting parts of tobacco leaves can be divided into five parts: the lower 2-3 leaves of the tobacco plant are called foot leaves; the upper 4-5 leaves are called lower second shed leaves; the middle 4-6 leaves are called waist leaves ; The 4-5 leaves in the middle are called the upper second shed leaves; the 3-4 leaves at the top of the tobacco plant are called the top leaves. The foot leaves and the lower two shed leaves are collec...
