A kind of crop planting method for desertification land management

Abstract

The invention relates to a crop planting method for desertification land control. Equipment is installed and pipelines are laid in the desertification land; drip irrigation pipes are shallowly buried in the desertification land, and high-yielding varieties with high yield are used to implement wide and narrow row no-tillage dense planting, so as to The drip irrigation pipe is used as the axis to adjust the row spacing to realize the narrow row planting of the original stubble, and complete the no-tillage planting of straw cutting, sub-row subsoiling, precise on-demand sowing, and soil covering suppression at one time; irrigation of seedlings, weeding, and pest control; full nutrition throughout the growth period Element balanced fertilization, that is, after sowing, the whole process of crop growth and development implements balanced fertilization of all nutrient elements dissolved in irrigation water. Different water-soluble fertilizers are used in stages, and are applied to the roots of crops with drip irrigation until the crops are harvested. The present invention provides a guarantee for balanced, precise and efficient fertilization of all nutritional elements during the growth period of crops by means of pulse-type intermittent irrigation. The method is applied to desertified land to obtain high-yield crops, and the desertified land is fundamentally controlled after 3 to 10 years of alternating cycles.

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...

Problems solved by technology

[0004] In view of the characteristics of desertified land in the prior art and the problems of uneven water and fertilizer and uneven growth of crops caused by drip irrigation under plastic film in the prior art, the technical problem to be solved by the present invention is to provide a method that can solve the problem of poor water retention and water retention in desertified soil. Fertilizer problem, crop planting method for desertification land management to obtain high yield of crops while desertification land management
