Abstract

The invention discloses a green covering production mode of spring wheat-winter rape-vicia sativa, aiming at the low resource utilization rate of the one-year-old cultivation mode in the Northwest Oasis Irrigation District, the continuously depleted crops and the degraded quality. The winter rape is planted after the spring wheat, and vicia sativa is planted after harvesting winter rape, which cannot only make full use of water and heat resources, but improve soil physical and chemical properties to improve its fertility with green manure while great and stable harvest is ensured, thereby achieving planting mode of 'fertile field with field', 'fertile land with land' and 'combination of utility and protection'; besides, the green plants in winter can effectively reduce wind erosion and reduce sandstorms in the northwestern arid regions.

Description

technical field [0001] The invention relates to the technical field of planting agricultural products, in particular to a spring wheat-winter rapeseed-arrow pea annual green mulching production method. Background technique [0002] Oasis refers to a heterogeneous ecological landscape that can be maintained relatively stably and has obvious microclimate effects based on a small-scale but considerable-scale biological community based on a large-scale desert background matrix. A considerable scale of biological communities can ensure the stability of the oasis in space and time and the systemic structure; its microclimate effect ensures that the oasis can have a suitable climate environment for human and other biological population activities, which is conducive to the formation of a healthy growth of landscape ecology biological chain structure. [0003] The traditional oasis irrigation area in Northwest China adopts the cultivation mode of one crop per year, which has promin...
