摘要
在宁夏固原市郊大堡试验场进行了玉米双垄全膜覆盖沟播密度试验,结果表明,采用全膜双垄沟播技术,种植密度以75 000株/hm2为宜,最佳产量达11 955 kg/hm2,比常规种植密度60 000株/hm2增产16.2%。
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.
