Farmland mulching film fixing method and device

Abstract

The invention discloses a farmland mulching film fixing method and device. According to the method, soil preparation and ridging are conducted according to the cultivation requirement of a crop to be planted before seeding in early spring, and ridge height is 15-18 cm; film mulching is conducted with a film mulching device, a set of press film and nailing device is arranged in each furrow, and the film mulching device drives the nailing devices; a mulching film is laid flat firstly, film pressing is conducted with a rubber roller at each furrow, nailing is conducted with the nailing devices at each furrow, and nailing distance in each furrow is consistent with planting distance or is one half of planting distance; the connecting position of two pieces of the mulching film is arranged in the furrows and nailed, and the periphery of the whole field needs to be covered and pressed firmly with soil. The device adopted in the method is composed of an air pump (1), a cylinder (4) and a nail driving device. According to the method, the periphery of the field is covered with soil, nailing is conducted in the middle, nails are degradable, and the mulching film can not be broken under tension caused by wind blowing and soil pressing so as to be picked conveniently. The position of a nail in each furrow is consistent with a corresponding hole sowing position, and a funnel shape is formed, so that rainwater collection is convenient.

Description

Technical field [0001] The invention relates to a method and equipment for fixing mulch film which is convenient for the recovery of mulch film in farmland. Background technique [0002] At present, a large number of mulch films are used to cover farmland in dry land in the north for heat preservation and reduction of water evaporation. In the mulching process, in order to prevent the mulch film from being lifted by wind and frictional damage, the nearby soil is taken to compact the film. Due to the uneven thickness of the soil on the cover film After natural weathering, the plastic film tends to become fragmented after the autumn crops are harvested. In particular, the film buried in the soil is separated from the bare film, and the film buried in the soil is not easy to pick up, causing difficulty in recycling and polluting the farmland. Aiming at the pollution of film fragments formed by covering the soil, a method for covering the film and a device for applying the method ar...
