Plastic film mulching technique allowing peanut seedlings to automatically growing out of film

Abstract

The invention relates to a plastic film mulching technique allowing peanut seedlings to automatically growing out of a film. The technique comprises the steps of 1, land selection, fertilization and furrowing or ridging; 2, making shallow trenches on the surfaces of furrows or ridges; 3, sowing at the depth of 1+ / -0.5 cm; 4, marking the positions of seeds, and conducting plastic film mulching; 5, covering a plastic film with a layer of soil along marking lines; 6, needing no artificial film rupture or movement of soil on the film.

Description

technical field [0001] The invention relates to a plastic film covering technique for peanut cultivation. Background technique [0002] The film-mulched cultivation of peanuts has a history of decades. It has been widely used in Northeast China and North China. It has good economic benefits and is widely welcomed. The main steps of peanut plastic film mulching technology are: first fertilize the land, make flat borders, high borders, or ridges, and then ditch the furrows or ridges, water, sow, level columbine, spray herbicides, and then use a thickness of 4- The ground is covered with a 6-micron transparent plastic film, and the two sides are compacted with soil to maintain moisture and increase temperature. After the peanut seedlings are unearthed, a hole is dug out of the film from the seedling part by hand, so that the seedlings are exposed outside the film. [0003] The above-mentioned traditional peanut mulching cultivation technology has the following disadvantages: ...

Problems solved by technology

[0003] The above-mentioned traditional peanut mulching cultivation technology has the following disadvantages: First, the peanut seedlings need to grow in the space outside the plastic film, so it is necessary to manually dig a hole in the film after the peanuts emerge, so that the seedlings are exposed outside the plastic film through the hole. Otherwise, the seedlings will be injured and die if they are trapped under the mulch, and the workload of manually digging the hole from the mulch is large, time-consuming, and labor-intensive. Second, peanut seedlings need to grow in the space outside the mulch, but often For some reasons, it is too late to artificially rupture the membrane, and the peanut seedlings are trapped in the membrane, resulting in injury and death, resulting in reduced production

Third, in the event of strong winds and bad weather, the mulch film is easily blown and floated by the wind from the artificially generated holes, resulting in loss of the mulch film

Fourth, this technology is not suitable for mechanized operations because of the need for manual rupture of the membrane, which is labor-intensive and time-consuming
