于2012年5月~2012年6月在新疆农业大学草地生态试验站进行高冰草种子繁育基地建立——高冰草生物学特性观测实验,结果表明:高冰草于4月6日就返青,4月12日分蘖,5月8日拔节,总生育期天数为32 d;返青期高度为3.20 cm、分蘖期高度为15.90 cm、拔节期高度为49.80 cm;返青期至分蘖期的生长速度为1.81 cm/d,分蘖期至拔节期生长速度为1.30 cm/d。分蘖期分蘖数为70个/株,茎粗为1.58 mm,单枝叶数为3个,叶长为25.31 cm,叶宽为0.40 cm,叶鞘长为5.70 cm,叶面积为4.9 cm2,叶重0.96 g。
From May 2012 to June 2012, the experiment of establishing the high-ice grass seed breeding base-the experimental observation of the biological characteristics of the tall ice grass was conducted at the Grassland Ecological Experimental Station of Xinjiang Agricultural University. The results showed that the tall ice grass returned to green on April 6 , Tillering on April 12, jointing on May 8, and the total number of days of the growing season was 32 days. The height of returning stage was 3.20 cm, the height of tillering stage was 15.90 cm, the height of jointing stage was 49.80 cm, the growth rate from turning green stage to tillering stage 1.81 cm / d, and the growth rate from tillering stage to jointing stage was 1.30 cm / d. The number of tillers at tillering stage was 70, the stem diameter was 1.58 mm, the number of single branches was 3, the leaf length was 25.31 cm, the leaf width was 0.40 cm, the leaf sheath length was 5.70 cm, the leaf area was 4.9 cm2 and the leaf weight was 0.96 g.
