Embodiment Construction

[0018] A technical method for cultivating flue-cured tobacco under film, comprising the steps of:

[0019] 1) Seedling cultivation

[0020] 1) Seedling raising method

[0021] All use trays for seedling cultivation;

[0022] 2) Sowing

[0023] The sowing rate of coated seeds is 15 grams per square meter, and every 0.6 mu of greenhouses can bear 100 mu of field tobacco seedlings. Sow on March 14, and apply 1.5 kg of compound fertilizer per 10 square meters of mother bed as base fertilizer;

[0024] 3) Seedbed management

[0025] For seedlings in the small cross period, the distance between seedlings is about 1.5cm. During the period from "three leaves and one core" to "four leaves and one core", uniform tobacco seedlings are selected for false planting, and fertilizer and water control are cut off 5 days before transplanting. Ventilation, cut the leaves once when sealing the tray, prepare for transplanting, spray virus inhibitors the day before cutting the leaves and transp...

Abstract

The invention provides a technique for cultivating cured tobaccos under a mulching film, which belongs to the technical field of tobacco seedling culture. The invention aims to provide cured tobacco culture and matching techniques under the mulching film, which can effectively prevent aphid-transmitted virus disease, increase production and improve the quality. The cured tobacco culture under the mulching film comprises the following steps of: seedling culture, ridge forming, fertilization, transplantation and management after planting. The technique provided by the invention has the following advantages that: the seedling stage is short, the used land is saved, the operative technical links are simple, and the cost is saved; the invasion of field virus diseases is light; lower tobacco leaves develop well and have high availability; premature flowering is reduced or avoided; effective leaves of tobacco plants are increased, the root system is developed, a double-layer root system is obvious, lodging is prevented, and straws and pieces are opened well; and the yield and quality benefit is obvious improved compared with that of a common tobacco field.

Description

technical field [0001] The invention belongs to the technical field of tobacco seedling cultivation, in particular to a technical method for cultivating flue-cured tobacco under film. Background technique [0002] Tobacco is an important economic crop in our country. At present, in many areas of our country, tobacco planting is an important source of income for local farmers. The harm of diseases and insect pests in tobacco planting is huge, especially the harm of aphid-borne virus disease to tobacco planting. At present, aphid-borne virus disease has become one of the main factors restricting the development of tobacco leaf production. After tobacco is infected with viral diseases, the yield decreases and the quality deteriorates. At present, there is no pesticide with good curative effect on viral diseases in the world. The fundamental way to prevent and control viral diseases is to control aphids. However, due to the large number of aphid hosts and the limitation of the ...
