| 摘 要： | 龙须草系禾本科拟金茅属多年生草本植物。生育期长(250天左右),分蘖力强,一年可达100蘖以上。生殖生长期短,营养生长期长,6月上旬籽实成熟后,才进入旺盛的分蘖期。分蘖力受草龄、插种期、温度、光照、水分、土壤肥力和坡向等因素的影响而异。龙须草分蘖动态变化可分为始增期、快速期、高峰期和缓增期等四个时期。

| Abstract: | The Eulaliopsis binata (Rotz.) C. E. Hubb is the perennial herb in the Eulaliopsis Honda of the Gramineae. Almost 250 days are needed for its long growth period. Its tillering ability is strong and may reach 100 tillers in a year. The reporductive period is shord but its vegetative period is long. Its caryopsis ripens in the first ten-days of June and then starts vigours tillering stage. The tillering vigour is controlled by the grass age, seed sowed time, sun light, water content, soil fertility and the direction of slope, etc. The tillering dynamics of Bulaliopsis binata may be divided into the initial stage, high speed stage, top stage and slow speed stage. |
