摘要
进行了玉米分带覆膜错窝密植高产技术研究。结果表明,玉米品种凉单4号面积为1 094.0 m2,平均产量15 674 kg/hm2;玉米品种成单30面积980.5 m2,平均产量15 024 kg/hm2;玉米品种齐单1号面积1 034.0 m2,平均产量14 766 kg/hm2;同一田块3 108.5 m2,3个玉米品种平均产量15 166 kg/hm2。
The super high yield maize cultivation technology of zoning-film mulching-stagger nest-close planting was studied.The results showed that planting area of cultivar Liangdan 4 was 1 094.0 m2;and the yield was 15 674 kg/m2.The planting area of Chengdan 30 was 980.5 m2;and the yield was 15 024 kg/m2.The planting area of Qidan 1 was 1 034 m2;and the yield was 14 766 kg/m2.The total area of the tested field was 3 108.5 m2;and the average yield of the three cultivar was 15 166 kg/m2.
