通过介绍不同种源楠竹造林,近3 a时间观察2个种源楠竹的发笋率、发笋量、生长量、立竹度等性状技术指标,发现广西母竹发笋率、发笋量比本地楠竹分别高出17%、3%和61株/hm2、138株/hm2、168株/hm2。立竹度各年比本地竹分别多出61株/hm2、138株/hm2、549株/hm2。本地楠竹竹径增粗快,竹壁厚,优良度要高,种植楠竹也可根据发展的目标和需求来确定种源。
Through the introduction of different provenances of bamboo plantations, the bamboo shoots, shoots, growth and stand characteristics of two provenances were observed in the past 3 years. Compared with the local bamboo, the yield was 17%, 3% and 61 plants / hm2, 138 plants / hm2 and 168 plants / hm2, respectively. The stand of bamboo each year than the local bamboo more than 61 plants / hm2, 138 plants / hm2, 549 plants / hm2. Bamboo thicker local bamboo thickening, thick bamboo wall, fineness is high, planting bamboo can also be based on the development goals and needs to determine provenance.
