A Study of Benefit and Technology for Double Ridge Whole-mulching Furrow Sowing Maize Intercropping Soybean

On the basis of 1 years of trials, 3 years of big area contrast display and 3 years of open-field yield and benefit comparative study, a technology mode of the double ridge whole-mulching furrow sowing maize intercropping soybean under the site condition of the arid and semi-arid area of the Southern Mountainous Area of Ningxia was found out. The effects of the technology on the yield and income increasing were significant and it was easy of operation and management and im- proved the dryland water-saving new technology system with the double ridge whole-mulching furrow sowing as the core. It has a good prospect for further extension and application.
