| Abstract: | A density test was conducted for double ridge whole-mulching furrow sowing corn at Dapu testing field in the suburb of Guyuan municipality in Ningxia. The result showed that with double ridge whole-mulching furrow sowing technology the suitable planting density was 75 000 plants/hm2 and the optimum yield reached 11 955 kg/hm2,an increasing of 16.2% compared with that of the common planting density of 60 000 plants/hm2. |
