摘要
本文对从东北三省引进的 2 7个玉米杂交种在西藏林芝和拉萨试验种植的结果进行了系统分析 ,结果表明 ,在海拔 30 0 0m的林芝 2 7个杂交种基本都能正常成熟 ,而在海拔 370 0m的拉萨 ,有 19个杂交种能正常成熟 ,四单 19,本育 9等杂交种有进一步引进繁育推广的价值。
The exepriments of introduction of 27 corn hybrids from the Northeast of China to Tibet Plateau were made in Linzhi and Lhasa.The results showed that almost all the hybrids could ripen normally in Linzhi at the altitude of 3000 meters,but only 19 hybrids could ripen in Lhasa at the elevation of 3700 meters.Several nicer hybrids like Sidan 19 and Benyu 9 could be introduced further for the reproduction and popularization in Tibet.
