高海拔地区玉米高密度种植比较试验

摘要

The 6 new hybrid maize combinations were compared test at an altitude of 2 550 m in Ganzi District.The results indicated that 5 tested combinations had moderate growth period,good plant type,lodging resistance,the yields were higher than the A dan 9(CK),adapted to the mountain,high mountain region growing in Ganzi District. Among them,Zao 3 combination and A dan 9(CK)reached significant difference in yield,which had very good production potential and value in use.%在海拔2550 m的甘孜州高山区对6个杂交玉米新组合进行品比试验，结果表明：5个参试组合生育期适中、株型好、抗倒伏，产量高于阿单9号(CK)，适应甘孜州高山、半高山区域种植。其中，早3与阿单9号(CK)产量达显著差异水平，有很好的生产潜力和利用价值。
