Problems solved by technology

Although the province's average annual rainfall is above 1000mm, which can fully meet the needs of flue-cured tobacco production in theory, but due to seasonal drought, uneven rainfall distribution, and excessive rainfall surface runoff loss, etc., the transplanting of flue-cured tobacco is often delayed by drought. Transplanting time: Drought and waterlogging often occur during the peak season of flue-cured tobacco, and the stress of summer and drought in the mature stage limits the stability of flue-cured tobacco production and the improvement of tobacco leaf quality in this area

Abstract

The invention discloses a tobacco half-film-covering cultivation method. According to the method, a mulching film is covered on the top of a ridge, and then planting holes for cultivation of tobacco seedlings are punched on the edges of the mulching film on the shoulder part of the ridge. The tobacco half-film-covering cultivation method has the advantages that tobacco is planted in a one ridge and double-line mode, and therefore transplanting between a wide line and a narrow line is achieved, ventilation and photopermeability of the tobacco at later stage are benefited, and tobacco leaf quality is improved; in the later stage growing process of the tobacco, the root system is located in the film and outside the film at the same time, and therefore characteristics of moisture preservation in the droughty situation and drainage in the rain-waterlogging situation are combined, and normal growing of the tobacco is benefited; the edges of the mulching film are connected with base fertilizer, the root system of the tobacco is close to and in contact with the mulching film and the base fertilizer, and therefore rain water can flow to the periphery of the root system easily along the film to dissolve the fertilizer and moisten the root system of the tobacco, the utilizing rate of the fertilizer is improved, and root system development and tobacco growing are promoted; and as the edges of the mulching film is adjacent to the basal part of the stem of the tobacco, when people stand on the ridge to uncover the film, the completeness of the mulching film is guaranteed, recycling efficiency of the mulching film is improved, and white pollution is effectively reduced.

Description

Technical field [0001] The invention relates to a field semi-film mulching cultivation method for flue-cured tobacco, belonging to the technical field of crop mulching cultivation. Background technique [0002] Ridge cultivation is a common method in crop cultivation and is widely used in flue-cured tobacco production. It has a positive effect on increasing the thickness of the soil layer, protecting moisture and drought, ventilating and preventing diseases, increasing the surface area of ​​the soil, expanding the light-receiving surface, raising the ground temperature, and promoting the development of crop roots. [0003] In my country's Guizhou Plateau tobacco area, the soil and arable layers are thin, the soil fertility is low, and the ability to retain fertilizer and water is poor. Although the province’s average annual rainfall is above 1000mm, theoretically it can fully meet the needs of flue-cured tobacco production, but due to seasonal drought, uneven rainfall distribution...
