Problems solved by technology

[0003] The purpose of the present invention is to provide a method for mulching farmland plastic film. By delaying the aging process of the plastic film and reducing the degree of damage, it can alleviate the aging and damage of the plastic film in the production practice of the existing farmland plastic film mulching cultivation. Effective recycling causes white pollution of farmland environment

Embodiment 1

[0012] For seedling transplanting field, such as figure 1 As shown, on the basis of applying sufficient base fertilizer and fine soil preparation, remove the dry soil on the surface of the mulching operation area 3 to both sides of the operation area, and cover the mulching film 2 according to the conventional mulching method, and stretch and straighten it when laying the film , Seal tightly, and the ground temperature rises rapidly after mulching to promote transplanting and returning seedlings. After transplanting and returning seedlings, remove the foreign matter such as stubbles and stones from the surface layer of fine soil that was previously piled on both sides of the mulching film laying operation area, and cover them evenly on the mulching film 2 Above, the soil protection layer 1 is completely covered until the crops are harvested. The thickness of the protective layer composed of surface fine soil is 2cm. In combination with conventional plastic film laying or intert...

Embodiment 2

[0014] For the areas where the frost-free period is short and need to increase the accumulated temperature to seize the farming time, on the basis of conventional plastic film mulching cultivation and applying sufficient base fertilizer for fine soil preparation, remove the dry soil on the surface of the plastic film mulching operation area to both sides of the operation area, grab moisture and cover the plastic film according to the conventional plastic film mulching method, and lay The film should be tightened, straightened, and tightly sealed. After the film is laid, the ground temperature will rise rapidly to promote seed germination. After the seeds germinate and germinate, the surface fine soil temporarily piled on both sides of the film laying operation area will be temporarily piled up in combination with the field operation of digging out the seedlings and sealing the soil. Remove root stubble, stones and other foreign objects and cover them evenly on the plastic film, ...

Embodiment 3

[0016] Different from Embodiment 1 and Embodiment 2, the sun protection layer is covered on the mulch film during the whole period from the laying of the mulch film to the harvest of the crops. This method can better protect the mulch film.

[0017] In other embodiments of the present invention, different from the above-mentioned embodiments, the conventional method of laying the plastic film does not need to clean the surface soil in the laying of the plastic film. The difference from the above-mentioned embodiment is that the thickness of the protective layer formed by the fine soil on the surface can also be determined according to It needs to be adjusted, and it can be 1cm or less than 1cm. In other embodiments of the present invention, different from the above-mentioned embodiments, the protective layer can also be soft crop straw or soft weeds such as rice straw and wheat straw, or it can be For other shading materials such as sunshade nets, two or three kinds of shading ...

Abstract

The invention relates to a method for covering a mulching film on farmland. The method comprises the following steps of: paving the mulching film in an operation area, firmly pressing the edges of the mulching film, and covering a protective layer on the entire surface of the mulching film in the whole period from the pavement of the mulching film to the harvest of crops or in the whole period from the germination of seeds of the crops to the harvest of the crops or in the whole period from the transplantation and rooting of the crops to the harvest of the crops, wherein the protective layer is at least one of shading materials such as field fine topsoil, soft crop straws, soft weeds and a sunshade net. By paving the protective layer on the mulching film, environmental conditions such as sunlight exposure, wind and rain are avoided, so that the aging and breaking process of the mulching film is effectively slowed; the using amount of mulching films is reduced by effectively prolonging the service life of the mulching films; and meanwhile, relatively intact residual films are preserved for recovery, so that the aims of saving cost, synergizing and reducing white pollution are fulfilled.

Description

technical field [0001] The invention relates to a method for mulching farmland with plastic film. Background technique [0002] As an advanced science and technology, plastic film mulching cultivation is used in field production. Its good characteristics of increasing temperature and moisture, water and fertilizer, improving soil physical and chemical properties, inhibiting weed growth and reducing diseases have played an important role in the transformation of agricultural production methods and the improvement of agricultural productivity. However, the plastic film is prone to aging and damage under the influence of wind, sun, etc., and the residual film scattered on the ground and in the soil cannot be degraded for a long time and cannot be effectively recycled. With the promotion and popularization of plastic film covering cultivation technology, the problem of "white pollution" is increasing In recent years, the film technologies such as photodegradable mulch film, biod...
