Embodiment Construction

[0014] Ridge several rows in the field, open the ridge top groove 1 along the ridge peak, the bottom of the ridge top groove is higher than the bottom of the ridge groove 2 between the two ridges, the width of the open box is 1300mm, and the width of the film is 1600mm. One film covers 4 rows of medium-density crops or 5 rows of high-density crops; the water-permeable plastic film adopts wave-shaped coverage, and when covering 4 rows of crops, there are 3 ridge grooves 2 and 4 ridge top grooves 1, a total of 7 waves, covering 5 rows of crops There are 4 ridge grooves 2 and 5 ridge top grooves 1 with a total of 9 waves; the ridge top groove 1 on the film is drilled for 3 seeds, and a small amount of soil is covered, which is beneficial to the emergence of seeds for precision sowing. The ridge groove 2 is The warming area is also the rainwater collection and infiltration area; the ridge top groove 1 is also called the seeding ditch, and the formation of the ridge top groove is fo...

Abstract

The invention provides a wave-shaped covering flow collection cultivation technical mode of a wide-width water-seepage mulching film, belongs to the technical field of crop cultivation and aims at further improving light, heat and moisture resource use ratio in drought and cold areas and greatly increasing crop yield in unit area. The wave-shaped covering flow collection cultivation technical mode is characterized in that a plurality of rows are ridged in a farmland, ridge top grooves are furrowed on ridge peaks along the ridges, the groove bottoms of the ridge top grooves are higher than groove bottoms of ridge grooves arranged between every two ridges, the width of the furrowed farmland is 1300mm, the width of the mulching film is larger than 1600mm, wave-shaped covering is adopted, holes are punched on the mulching film at the positions of the ridge top grooves for seeds to be sowed, and a little amount of soil is covered on the mulching film. The number of the ridges is determined according to crop species, four rows are needed to be ridged when medium-density crops are planted, five rows are needed to be ridged when high-density crops are planted, and the mulching film is wide in width and water permeable. By adopting the wave-shaped covering flow collection cultivation technical mode, seedlings can be emerged completely, earth temperature is improved, soil moisture content is increased and soil maturity is good.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, and in particular relates to a wave-shaped covering flow-collecting cultivation technology mode of wide-width permeable plastic film. Background technique [0002] Film mulching is an important cultivation technology that can maintain moisture and increase ground temperature. It plays a very important role in increasing crop yields in cold and arid areas. The area covered by plastic film in my country is more than 100 million mu, mainly distributed in North China, Northeast China and Northwest China. Tests have shown that with the increase of the width of the mulch, its ability to retain water and increase ground temperature is enhanced. At present, the width of mulch film commonly used in production is 800mm to 1200mm. If the width of the mulch film is increased to more than 1200mm, although the ground temperature can be significantly increased, the rainwater is not easy to enter under...
