High-yield cotton intercropping is an effective measure to increase the multiple cropping index and increase production efficiency. The cotton-white radish intercropping model has been used less and is easier to manage and has been widely welcomed by the people. (1) Variety selection White radish is selected from about 60 days of growth period, anti-seizure, suitable for spring cultivation, such as Changchun Dagen, and cotton is selected for pest-resistant, strong growth varieties, such as Pei 566, GK-12, SGK321 and so on.

(4) sowing The appropriate sowing date for white radish is April 5 to 10, sowing on both sides of the ridge, spacing 0.5 meters, spacing of 0.25 meters, density of 4850 plants/mu, and then covering the mulch on the ridge surface. The appropriate sowing date for cotton is from April 10 to 20, planted in the center of the ridge, with a row spacing of 1.1 meters, a plant spacing of 0.2 meters and a density of 3,000 plants/mu.
