Film-applying drop irrigation sowing earthing device

Abstract

The invention discloses a film-applying drop irrigation sowing earthing device which comprises a rack assembly, and a drip irrigation belt coiled stock, a film coiled stock, a seed box, a row marker assembly, a compacting roller, a film spreading roll, a film pressing edge wheel assembly and a film edge earthing disk which are arranged on the rack assembly. The film-applying drop irrigation sowing earthing device is characterized by also comprising a first earthing device assembly and a second earthing device assembly which are arranged at the rear side of a hole sowing device assembly. Through arrangement of the two earthing devices, the film-applying drop irrigation sowing earthing device meets the earthing requirement of a one-film three-pipe twelve-line mode; and due to the implementation of the one-film three-pipe twelve-line mode, the utilization rate of soil is remarkably increased, and the number of holes in unit area is also greatly increased.

Description

technical field [0001] The invention relates to film-covered drip irrigation sowing and soil-covering equipment, which belongs to the technical field of agricultural seeding and irrigation equipment. Background technique [0002] Rice is an important food crop in my country. Traditionally, it is mainly planted in paddy fields flooded with water (the water layer in the field is 3-10cm). my country is one of the 13 water-poor countries in the world, and it is also a large agricultural country. Agricultural water accounts for 30% of the total water consumption 70-80%, especially in arid and semi-arid areas, agricultural water consumption reaches more than 90%, while the total water consumption of paddy fields accounts for more than 65% of agricultural water consumption. Due to changes in the global climate in recent years, spring droughts and summer droughts have occurred frequently, resulting in large-scale production reductions in northern rice planting areas, which seriously ...

Problems solved by technology

[0003] Chinese patent CN101422120A discloses the "drip irrigation and dry farming method for direct seeding of rice under film", and its drip irrigation belt, film laying, and sowing are completed by a special planting machine at one time, but there is only one configuration scheme for the row spacing of rice and the drip irrigation belt in this technology. species, and after years of practice is not very reasonable

Moreover, the crop cultivation row spacing and drip irrigation belt configuration method in the field crop under-film drip irrigation cultivation technology widely promoted in Xinjiang cannot be directly applied to the rice production process due to various reasons.
