水竹的生物学特性

Biological characteristics of Phyllostachys heteroclada

水竹是一种具有良好开发前景的笋用竹种。对浙江省遂昌县白马山林场水竹生长特性的研究表明， 水竹笋期为４ 月中下旬至６ 月中旬， 其中５ 月３ 日至５ 月３０日为出笋高峰期， 是竹笋单产形成的重要阶段。末期延续时间较长， 此期应加强肥水管理， 以提高竹笋单株产量。为保证竹林的更新复壮， 根据秆形生长和枝叶生长特性， 应在出笋盛期做好留笋养竹工作， 留养新竹０４ ～０５ 万株·ｈ ｍ － ２·ａ － １ ， 使竹林密度保持在２０ 万株·ｈ ｍ － ２ 。

Two year studies on growth characters of Phyllostachys heteroclada in Baimashan Forest Farm of Suichang,Zhejiang Province,suggest that bamboo shoots emerge from the second ten days of April to the second ten days of June,falling mainly on 3～30 May.In order to increase individual shoot weight,fertilizer and water management is necessary,especially in the later stage of shoot emergence.New bamboo culture should be done in the peak stage of shoot emergence,with 4 000～5 000 new bamboos per hectare.The density of twety thousand bamboos per hectare are suitable for a high production grove.
