Crop cultivation method for desertification land control

Abstract

The invention relates to a crop cultivation method for desertification land control. Device installing and pipeline laying are achieved in desertification lands; drop irrigation pipe shallow burying is conducted in the desertification lands, wide and narrow row spacing tillage-free encryption plantation is conducted on density-resistant and high-yield varieties, spacing adjustment is conducted with drop irrigation pipes as axes so that original crop narrow spacing plantation can be achieved, and the tillage-free plantation of straw cutting, under-spacing deep loosening, precise hill seedling and covered soil pressing is completed at a time; emerging water irrigating, grass removing and plant disease and inset pest control are achieved; full nutrient elements are applied uniformly during the full growth period; that is, after sowing, uniform applying of the full nutrient elements dissolved with irrigation water as a carrier is executed in the whole crop growth process, and different types of water-soluble fertilizer are used at different stages and are applied into root parts of crops to be obtained by the crops through drop irrigation. The uniform, precise and efficient applying of the full nutrient elements during the crop growth period is ensured through an impulse type intermittent rotation flow measure, the high yield of crops is achieved when the method is applied to the desertification lands, and the desertification lands are fundamentally controlled through alternate circulation within 3 years to 10 years.

Description

technical field [0001] The invention relates to a crop planting method for controlling desertified land. Background technique [0002] In the arid areas of the north, due to the small rainfall, uneven seasonal distribution, large evaporation, and vegetation destruction, land desertification is becoming more and more serious. The current farming methods expose a large area of ​​arable land in winter and spring, especially for annual drought-tolerant crops whose fruits are in sandy soil, such as peanuts, potatoes, sweet potatoes, etc. After harvesting, the arable land is no different from the desert, further deteriorating the ecological environment , frequent sandstorms and dust drift cover new arable land, increasing the area of ​​land desertification, reducing crop production, and further affecting national food security. [0003] At present, the technology of drip irrigation under mulch to save water and increase grain is widely used in arid areas, and has achieved certain...
