| 摘 要： | 本文对克氏针茅（StipakryloviiKoshev．）繁殖的生态生物学特性的研究结果表明，在整个生育期内，分蘖的产生有两个峰期（拔节期和果后营养期）．分蘖枝的产生与不定根的形成在幼苗阶段有一定的相关性。当幼苗2月龄时，这是不定根接管种子根大部分作用的关键时期。群落中种子繁殖能力弱的主要原因是土壤紧实，种子入土困难，自然萌发能力低；不定根生长受阻，实生苗成活率低。

| Abstract: | This paper discussed the ecobiological characteristics of Stipa krylovii.The results show that the tillering of Stipa krylovii in whole growing season primarilyoccurs during the elongation stage and the fruit bearing stage. There is a correlation between the occurance of tillering shoots and tbe emergence of adventious roots. The weakseedling propagation of Stipa krylovii is mainly caused by difficulies of seed being burried in compacted soil,low natural viability,growth of adventious roots being inhibitedand low seedling survival rate. |
