Powder ridge deep-cyclone water-storage seedling-retaining growth promoting and cultivation method in arid and semi-arid regions

Abstract

The invention discloses a powder ridge deep-cyclone water-storage seedling-retaining growth promoting and cultivation method in arid and semi-arid regions. The middle of a cultivating area is deep-ploughed by using a rotary tillage spiral type machine while the two sides of the cultivating area are shallow-ploughed; the soils are milled at the same time; the soils are naturally ridged after the soils are rotated in a deep mode and loosened so as to form a T-shaped ridge land of which the two sides are surrounded by shallow loosening soils and the inclined surfaces have a certain angle. Drainage channels are arranged in a non-cultivation area, a film covers the ridge land, planting holes are formed in the ridge land, and a water-storage tank for storing water and retaining water is established around the planting holes; meanwhile, standardization farm operations such as fertilizer application and pesticide application are carried out, so that the operation is finished mechanically and integrally once, and the labor efficiency is greatly improved; by using the cultivating method, the water content of the soil is effectively increased by more than 30 percent, the production of crops is increased by more than 40 percent, and the economic benefit is obviously increased; moreover, a new ecological balance system is established, and the method has a great popularization value in the northwest arid region.

Description

technical field

[0001] The invention relates to a farming method for crops, in particular to a farming method for deep-rotating water storage in a ridge in an arid and semi-arid area to preserve seedlings and promote growth. Background technique

[0002] Fenlong cultivation technology is a new farming technology invented by Wei Benhui, a researcher at the Economic Crops Research Institute of Guangxi Academy of Agricultural Sciences, which uses a tractor-driven mechanical helical drill to cut vertically and horizontally to crush the soil and directly plant crops. Yuan Longping, the father of hybrid rice and an academician of the Chinese Academy of Engineering, once proposed that in order to obtain ideal high yields of crops, it is necessary to have "good seeds + good fields + good methods". Practice has shown that "Fenlong" provides the possibility to further improve the quality of cultivated land and the improvement of farming methods. In an experimental field of the Guangx...
