Special machine for ridging, film mulching, film surface rainwater collection and efficient cultivation of potatoes in dry land

Abstract

The invention belongs to the technical field of agricultural machinery, and discloses a special machine for ridging, film mulching, film surface rainwater collection and efficient cultivation of potatoes in dry land. A mechanical cross beam is arranged, a soil rotary tilling device is mounted at the front end of the mechanical cross beam, a fertilizer box is mounted at the upper end of the mechanical cross beam, and a power mechanical soil feeding device is connected to the soil rotary tilling device through a chain; the mechanical soil feeding device is connected with four soil dividing and film pressing grooves; a water supplementing barrel is arranged at the upper end of the soil dividing film pressing grooves; and a double-ridging furrow plough, a mulching film mounting cross rod, a film breaker, a film mulching scraper and other one-time double-ridging film mulching ridge middle film breaking, earthing and pressing devices are arranged at the lower end of the mechanical cross beam. Each performance of the special machine completely meets the technical index requirements of a 'ridging, film mulching, film surface rainwater collection and high-efficiency cultivation technology for potatoes in dry land', and potatoes, beet and other crops needing ridging for planting are sown in arid areas and semi-arid areas.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a special-purpose machine for high-efficiency rain-collecting cultivation of potatoes on dry land with film-covered surfaces. Background technique [0002] At present: Ridging and film-covering ridge and furrow water collection cultivation technology is used in potato cultivation, and the average yield of the test is 47258.7kg / hm 2 , the potato growth period was significantly extended, the plants grew vigorously, the number of tubers per plant, the weight of tubers per plant, and the weight of each tuber increased to varying degrees, which was 15.2% higher than that of the control, and the water use efficiency was 90.07kg / hm 2 / mm, an increase of 14.81% compared with the control. However, due to the lack of sowing machinery that matches the technology and the lack of labor, the popularization and application of ridge-covering and film-covering ridge-di...

AI Technical Summary

Problems solved by technology

[0003] To sum up, the problems existing in the prior art are: currently widely used crop ridge film-covered drought-resistant cultivation seeders mostly adopt wide-ridge film-covering, film-on-film planting or film-side planting techniques; wide-ridge film-covering film-on-planting Although the technology can increase the soil temperature and reduce water evaporation, the mulching film prevents the rainwater from infiltrating into the soil and diverts the rainwater to the film measuring furrows, which cannot gather the limited precipitation at the roots of the crops and fail to achieve the purpose of rain collection. The current technology cannot solve the technology of seedling emergence and membrane breaking; although planting on the side of the film can solve the problem of seedling release, it will also collect limited rainfall on the roots of the crops, but this technology has a small area of ​​film covering in the field and serious water loss.
