摘要
以西藏较大面积种植且具代表性的6种类型青稞品种(系)14-3492、13-5171-7、藏青16、藏青17、藏青18、藏青20为试验材料,以品种为主区,以8个种植株距5.00、4.00、3.30、2.85、2.50、2.20、2.00、1.80 cm为副区进行裂区试验,研究了6个不同品种8个株距下的主要农艺性状和产量的差异性。结果表明,随着种植株距的增加,6种青稞品种的株高、分蘖数、穗长、小穗数、穗粒数、穗重呈下降趋势,产量呈增加趋势。
Six representative highland barley varieties(lines) 14-3492, 13-5171-7, Zangqing 16, Zangqing 17, Zangqing 18 and Zangqing 20 planted in a large area in Tibet were used as experimental materials. In order to study the differences of main agronomic characters and yield of 6 different varieties under 8 different plant distances, the split plot experiment was carried out in the main planting area with eight plant distances of 5.00, 4.00, 3.30, 2.85, 2.50, 2.20, 2.00 and 1.80 cm.With the increase of plant spacing, the plant height, tiller number, ear length, spikelet number, grain number per ear and ear weight of six highland barley varieties showed a downward trend, while the yield showed an increasing trend.
