摘要：

为了解几个早熟青稞品种在高寒半农半牧区的生态适应性。以‘浪卡子当地品种’为对照,‘喜拉23’、‘藏青17’、‘藏青690’、‘隆子黑青稞’、‘T28’共6个青稞品种在浪卡子县进行试种,相同的播种和田间管理,对青稞生长情况、产量和品质进行分析。结果表明：（1）6个青稞品种在浪卡子县均能正常成熟,6个品种平均株高60.50~91.09 cm,除‘T28’外其他4个青稞品种株高均高于‘浪卡子当地品种’青稞,其中‘喜拉23’平均株高91.09 cm,较当地品种的68.00 cm高23.09 cm,增高33.96%;（2）秸秆生物量：‘喜拉23’(9239.50 kg/hm2)>‘隆子黑青稞’(7135.75 kg/hm2)>‘藏青17’(6301.33 kg/hm2)>‘藏青690’(5678.00 kg/hm2)>‘T28’(5318.17 kg/hm2)>‘浪卡子当地品种’(4357.67 kg/hm2);（3）籽粒产量：‘藏青17’>‘喜拉23’>‘藏青690’>‘隆子黑青稞’>‘浪卡子当地品种’>‘T28’,‘藏青17’的籽粒产量较‘浪卡子当地品种’增产52.42%,其次为‘喜拉23’籽粒产量较‘浪卡子当地品种’增产50.05%。‘喜拉23’、‘藏青17’、‘隆子黑青稞’能适应浪卡子县的生态环境,且取得较稳定的生物产量和籽粒产量。

Abstract:

To understand the ecological adaptability of several early-maturing highland barley varieties in alpine, semi-agricultural and semi-pastoral areas, ‘Langkazi local highland barley variety’ (CK), ‘Xila23’, ‘Zangqing17’, ‘Zangqing690’, ‘Longzi heiqingke’ and ‘T28’ were planted. Under the same seeding and field management, the growth, yield and quality of these varieties were analyzed. The results showed that: (1) the six highland barley varieties could mature normally in Langkazi County, the average plant height of the six varieties was 60.50-91.09 cm; except ‘T28’, the average plant height of the other 4 testing varieties were higher than that of CK, especially the average plant height of ‘Xila23’, which was 91.09 cm, and 23.09 cm higher than that of CK (68.00 cm), increased by 33.96%; (2) the sequence of straw biomass of the six varieties from high to low was ‘Xila 23’ (9239.50 kg/hm2)>‘Longzi heiqingke’ (7135.75 kg/hm2)>‘Zangqing17’ (6301.33 kg/hm2)>‘Zangqing690’ (5678.00 kg/hm2)>‘T28’ (5318.17 kg/hm2)> CK(4357.67 kg/hm2); (3) the sequence of grain yield of the six varieties from high to low was ‘Zangqing17’>‘Xila 23’>‘Zangqing690’>‘Longzi heiqingke’>CK>‘T28’; the grain yield of ‘Zangqing17’ increased by 52.42% compared with that of CK, followed by that of ‘Xila23’, which increased by 50.05% compared with that of CK. ‘Xila23’, ‘Zangqing17’ and‘ Longzi heiqingke’ can adapt to the ecological environment of Langkazi and achieve relatively stable biological yield and grain yield.

Key words: alpine, early-maturing highland barley variety, biological yield, grain yield
