Abstract

The invention discloses an organic tobacco field planting and field managing method, which comprises the following steps: preparing land and ridging, transplanting tobacco seedlings, applying fertilizer in fields, performing field management and pest control, and harvesting manually, wherein the section of a ridge is ladder-shaped, the ridge spacing is 100-120cm, the ridge height is 20-25cm, drainage ditches are formed according to the height of terrain, the tobacco seedlings are transplanted with the plant spacing of 45-55cm, watered with enough water, covered with soil, and covered with a mulching film, and the mulching film is broken to expose the seedlings, base fertilizer is applied before ridging and during the transplanting and topdressing is applied after the transplanting, the field management comprises seedling deficiency check and seedling supplementation, film removal, earthing up, water replenishing, topping, leaf retention and sprout removal, and the pest control comprises comprehensive control and chemical control. According to the organic tobacco plantation and management requirements, organic fertilizer is adopted, and a harmless medicament or biological agent is used for the pest control, so that the organic production of the tobacco is realized. Compared with the regular tobacco production method, lead, mercury, cadmium, arsenic, copper, chromium and other harmful elements as well as the residual quantities of imidacloprid, emamectin benzoate, permethrin, fenvalerate, thiamethoxam and other main pesticides can be obviously reduced.

Description

technical field [0001] The invention belongs to the technical field of tobacco production, and in particular relates to a field planting and field management method of organic tobacco. Background technique [0002] According to historical documents, tobacco was introduced into my country from the Philippines, Vietnam, and Korea in the 16th century, but it was quickly accepted by people. After more than 400 years of planting and dissemination, tobacco has been widely distributed in my country, starting from the coast of the Yellow Sea in the east, reaching Ili in the west, starting from Hainan Island in the south, and ending between Baishan and Heishui in the north, at 74°~135° longitude and 180° latitude. In the range of °~53°, from the Turpan Basin below sea level to the plateau mountains above 3000m above sea level, tobacco footprints are everywhere. Tobacco production has high requirements on land fertility, and it is generally necessary to select fertile planting plots a...
