摘　　要：通过3个种植方式(起垄、补水机播、渗水膜覆盖;机播、普通膜覆盖;露地机播)和3个种植密度(7.5万,6.5万,5.5万株/hm2)对特早熟玉米并单16号在高寒冷凉区进行高产配套技术集成试验。结果表明,并单16号特早熟玉米品种在起垄、补水机播、渗水膜覆盖处理条件以及密度在7.5万株/hm2下籽粒产量和生物产量最高,水分利用效率也最高;露地机播条件下籽粒产量和生物产量以及水分利用效率最低,密度5.5万株/hm2条件下籽粒产量最低。由此得出,特早熟玉米品种并单16号在高寒冷凉区最适宜的栽培模式为起垄、补水机播、渗水膜覆盖+密度7.5万株/hm2。To study the optimal cropping pattern of Bingdan 16 in alpine cold region which is one of special premature maizes, the article conducted high yield technology integration test by three planting ways （ridging, replenishment sowing machines, water seepage membrane covering; sowing machines, ordinary film covering; open field sowing machines） and three planting densities（75 000,65 000, 55 000 plants/hm2）. The results showed that the grain yield and biological yield of Bingdan 16 was the highest, and water use efficiency was also the highest in the condition of planting by ridging, replenishment sowing machines, water seepage membrane covering and the density 75 000 plants/hm2. The grain yield and biological yield of Bingdan 16 was the lowest in the condition of planting by open field sowing machines and the grain yield was the lowest in the density 55 000 plants/hm2. In a word, the optimal cropping pattern of Bingdan 16 in alpine cold region is ridging, replenishment sowing machine, water seepage membrane covering and the density 75 000 plants/hm2.
