摘要
对扬州大禹风景竹园的黄纹竹出笋、退笋以及幼竹高生长规律进行了研究,结果表明:黄纹竹发笋期在3月下旬至6月下旬,4月13日至5月10日发笋数最多;退笋多出现在末期;高生长模型符合Logistic曲线模型和Doseresp曲线模型;生长盛期时,昼夜24h平均生长量达22.38cm,白天生长量是夜间生长量的1.29倍。
The shooting and shoot degradation Phyllostachys vivax f. huanvenzhn J .L. Lu as well as the height growth of young bamboo were studied in Dayu Scenic Bamboo Garden in Yangzhou, Jiangsu. The results indicated that the shooting period of lasted from late March to late June and most shoots emerged from 13th April to 10th May, while shoots degradation most occurred in the late June. The logistic equation of height growth was： H=517.593/1＋e6505-0.231wt. During the high growth period, the average height growth in 24 h at a day amounted 22.38 cm, while the daytime height growth was 1.29 times higher than that in the night.
