The pure income between the three cottons and cottonseed increased 75.5% and 37.1% respectively compared with the single cotton control. Cotton varieties should be high resistant to bollworm, high yield, sweet potato varieties should be short, early maturing, forage varieties should be cold-resistant and suitable for winter and spring growth; 2m area, cotton and sweet potato two rows of planting styles to maintain 1050kg / hm ~ 2 lint yield, the highest benefit; about October 25 sowing ryegrass, seeding rate of 75 ~ 150kg / hm ~ 2, sowing rye grass in early November, sowing rate of 150 ~ 225kg / hm ~ Intercropping than single cotton field water consumption increase is not obvious, its irrigation management with the same for cotton.
