The present application relates to the technical field of
crop cultivation in cold and
arid regions, and discloses a high-quality and high-efficiency strip
intercropping cultivation method for highland barley and rape in cold and
arid regions. In view of the problems of insufficient accumulated temperature, frequent spring drought, poor soil, low yield of single
cropping, disordered traditional
intercropping structure, low water and
fertilizer utilization rate, and
high incidence of diseases in high-altitude cold and
arid regions, the present application adopts a highland barley and rape wide-narrow strip high-low layer three-dimensional
intercropping patent configuration, and a supporting technical
system of precise seeding based on
soil temperature threshold, seed pretreatment, soil testing formula gradient fertilization, whole growth period grading soil
moisture management and control, green
pest control, segmented mechanical harvesting and
straw full amount of field returning and fertilization. The present application reconstructs the field
microclimate and water and soil
resource utilization mode through the high complementarity of the spatial
ecological niche, root
ecological niche and
nutrient time sequence ecological niche of highland barley and rape, realizes
water saving and
soil conservation, grain and oil yield increase,
soil fertility improvement,
pesticide reduction and
disease control, and full-process
mechanization adaptation, and is suitable for large-scale popularization and application in high-altitude cold and arid planting areas.
