Problems solved by technology

Because the soil temperature is easy to generate high temperature after the dry sandy land is covered with plastic film, in the case of severe drought, it will cause a decrease in production
On barren land, it is inconvenient to topdress after mulching, and the basal fertilizer is insufficient when sowing, and mulching cannot increase production.
Heavy sticky soil is difficult to rake and break when it is dry, and it is difficult to stick to the ground after covering the film. When the wind blows, the film is easy to break and run away.

Embodiment 1

[0017] Example 1, such as figure 1 Shown, the specific implementation steps of the present invention are:

[0018] (1) Site selection: Select a smoke field with a soil depth of more than 30cm and gentle terrain.

[0019] (2) Soil preparation: deep plowing before ridge formation, the depth of the plow layer should be more than 15cm, after plowing, rake evenly, and remove the sundries in the smoke field.

[0020] (3) Base fertilizer application: Before ridge formation, apply flue-cured tobacco base fertilizer in strips according to the amount of fertilizer required by conventional tobacco leaves.

[0021] (4) Ridging: Single ridge 1 is used, and the ridge 1 is erected after the rainy day before planting. Ridge height: 22cm-25cm for soil smoke, 25cm-28cm for field smoke, and 40cm wide at the top of the ridge body. It is required to dig deep and loosen the bottom of the ridge when raising the ridge, so that the ridge body is loose, the ridge is straight, the soil is fine, full,...

Embodiment 2

[0026] Example 2, such as figure 2 Shown, the specific implementation steps of the present invention are:

[0027] (1) Site selection: Select a smoke field with a soil depth of more than 30cm and gentle terrain.

[0028] (2) Soil preparation: deep plowing before ridge formation, the depth of the plow layer should be more than 15cm, after plowing, rake evenly, and remove the sundries in the smoke field.

[0029] (3) Base fertilizer application: according to the distance between the rows of tobacco plants between ridges of 90-100cm, and the distance between rows of tobacco plants of 110-120cm between two ridges, open a 15cm deep small ditch along the direction, and apply base fertilizer according to the amount of base fertilizer applied to conventional flue-cured tobacco strips before ridge formation .

[0030] (4) Ridging: Double row flat ridges 1 are used, and the ridges are opened according to the 210cm bottom of the ridge to form a ridge 1 with a width of 150-160cm. The h...

Abstract

The invention discloses a covering method and a structure for a degradable film of flue-cured tobacco ridge culture. The covering method comprises the steps of forming a land ridge in the field after land preparation and fertilization, laying non-woven fabric sprayed with a herbicide layer on the land ridge, covering the land ridge covered by the non-woven fabric with a fine soil layer, forming flue-cured tobacco cellar transplantation holes in the land ridge provided with the non-woven fabric and the fine soil layer, and planting tobacco seedlings in the flue-cured tobacco cellar transplantation holes. According to the method, flue-cured tobacco ridge culture covering with the non-woven fabric capable of preserving heat and moisture, being permeable to air and water and being capable of being degraded naturally and the fine soil layer covering the surface of the non-woven fabric is adopted, herbicide is combined with the non-woven fabric, and a novel weeding idea is proposed innovatively. According to the method, the flue-cured tobacco ridge culture and coverage mode is innovated, and the flue-cured tobacco ridge culture covering cultivation technology with the growing environment of the flue-cured tobacco optimized, coverage objects degraded naturally and pollution avoided can be achieved.

Description

technical field [0001] The invention relates to a covering method and structure of a degradable film for flue-cured tobacco ridge cultivation, and belongs to the technical field of crop covering cultivation. Background technique [0002] Flue-cured tobacco ridge cropping has been widely used in tobacco production and has achieved good results. Ridge farming and mulching film cultivation increase the thickness of the soil layer and the surface area of ​​the soil body, and have multiple effects such as warming and antifreezing, moisture conservation and drought prevention, drainage, soil and fertilizer, aphid and disease prevention, weed elimination and enhanced light. However, there are some adverse effects in plastic film mulching cultivation, such as covering plastic film for many years, resulting in decreased soil fertility and heavy white pollution. In production, dry sandy land, barren land, heavy clay and other lands are not suitable for mulching cultivation with plast...
