- 摘要:
- 为了筛选适合黑河地区种植的玉米品种，选取新选育的2个玉米新品种为试验材料，通过对不同年间2个品种不同密度下性状进行分析。同时利用不同种植密度下的表现，对小区产量进行比较分析。结果表明：2个品种随着种植密度加大，玉米各生育时期会相应推迟1～2 d。在密度加大的情况下，各品种在不同时期的生育进程、株高和穗位并没有因为密度的增加而存在较大的差异。德美亚1号适宜种植密度90 000株?hm-2；边单3号适宜种植密度75 000株?hm-2。
- Abstract:
- In order to select the suitable planting maize varieties in Heihe area,taking two new maize varieties as experiment materials,some characters of two varieties under different densities in different years were analyzed,while yield was analyzed under different planting densities.The results showed that two varieties with increasing of the planting density,different growing periods of maize would be delayed for 1 to 2 days.With the inereasing of density,there was no difference in period of growth and development,plant height and spike height.Suitable planting density of Demeiya was 90 000 plants?hm-2;Suitable planting density of Biandan 3 was 75 000 plants?hm-2.
