湘北低海拔坡地笋用毛竹幼竹人工摇梢抗倒伏效果分析

Analysis on Anti-Lodging Effect of Manually Shaking tip of Young Phyllostachys edulis in low-altitude Slope of Northern Hunan Province

毛竹(Phyllostachys edulis)是我国南方主要竹种。雨雪冰冻灾害严重影响笋用毛竹林的培育,造成竹株倒伏、折断,人工控制顶梢是笋用毛竹林抵御雨雪冰冻灾害的最有效手段。以湖南桃江为例,选取低海拔地区较大坡度地段的3处笋用毛竹林样地,对新生竹采取人工摇梢措施控制顶梢。结果表明:人工摇梢后的竹株能抗御雨雪冰冻灾害,人工摇梢不当会对新生竹造成一定损害,熟练掌握人工摇梢技术后可使这种损害控制在可接受范围。

Phyllostachys edulis is a major bamboo species found in southern China,where rain and snow seriously affect the cultivation of the bamboo stand for bamboo shoot,causing the bamboo plant to fall down and break off.The artificial control of top tip of bamboos is the most effective way for bamboo shoot to resist the negative effect from the weather.This paper takes Taojiang of Hunan Province as an example and selects three bamboo shoots grown in high slope in low-altitude areas as sample plots.New bamboo shoots are controlled by manualy shaking.The results show that after shaking,the bamboo plant can resist negative effects from rain and snow,but the improper conduct of shaking can also cause some damage to the new bamboo.The damage can be controlled if the way of shaking can be mastered by workers.
