The invention relates to an efficient planting pattern for cotton, helianthus annuus and corn intercropping and rotation in heavy chlorate clay saline-alkali soil in yellow river delta. A mode of intercropping and rotation of crops different in salt tolerance and salt absorption is adopted for the first time, a long-stalked crop (spring corn and helianthus annuus) wind strip and a green manure (summer corn) returning-to-field area are arranged, and through intercropping of annual crops of the planting mode, rational arrangement of crops for rotation, crop rotation of inter-annual crops and soil productivity cultivation and by comprehensive coordination of growth rate of different crops, efficient ecological planting of heavy clay saline-alkali soil with salt content reaching over 0.4% is realized. Annual intercropping is carried out for spring corn, cotton, helianthus annuus and summer corn, inter-annual crop rotation is carried for cotton and helianthus annuus, successive cropping obstacles of single crop are alleviated beneficially, and sustainable development of soil is guaranteed.
