摘　　要：从出笋、退笋、高生长规律3个方面对铺地竹的生长发育规律进行了系统的观察,结果表明:铺地竹从3月中旬开始陆续出土,一直到4月中旬,共持续37d。前期和盛期所出的笋成竹率比较高,并且所成的竹比较强壮。退笋一般发生在10cm以下的高度。竹秆的高生长遵循慢-快-慢的规律,历时39d左右,后期出土的笋能较快完成高生长是由于其生长初期和末期时间短的缘故。铺地竹高生长和土壤温度呈显著正相关关系。The shooting, shoot degrading and height growth of Arundinaria argenteostriata were systematically investigated in this paper. The results showed that bamboo shoot of Arundinaria argenteostriata was emerged from middle March to middle April, lasting 37 days. The bamboo shoots emerged during earlier and intermediate period had a higher survival rate. The height growth of bamboo culm was followed the slow-quick-slow pattern and usually needed about 39 days to finish the process. The reason why the shoots emerged later could finish their height growth quickly was that they had a short time of early growth stage and later growth stage. The height growth of Arundinaria argenteostriata presented a significantly positive correlation with the soil temperature.
