楠竹春笋的采伐,我省群众经验,通常在清明后5—7天一次集中采伐。但这只适合培育用材为主的楠竹林,对笋用竹林的采伐,目前国内报导还不多,有的认为以竹笋出土后3—5天割笋为宜。但因竹笋的生长速率,受林地土壤湿度、温度、光照等自然因素的影响较大,故以出土后时间而定,还不能完全达到合理采伐的目的。因此我们认为根据竹笋高度来采伐,不仪可以作到合理采伐,同时也便于采割时掌握。为了探求楠竹春笋采伐的最佳高度,我们于1986年4月—5月进行了楠竹春笋采伐高度的研究。研究采取典型抽样的方
Bamboo harvesting bamboo shoots, the people’s experience in our province, usually concentrated in the 5-7 days after the Ching Ming harvesting. However, this is only suitable for cultivation of timber-based bamboo forest, bamboo harvesting bamboo shoots, the current domestic reports are not many, some think bamboo shoots 3-5 days after excavated bamboo shoot is appropriate. However, the growth rate of bamboo shoots is greatly affected by the natural factors such as soil moisture, temperature and light in the woodlands. Therefore, the purpose of reasonable harvesting can not be fully achieved due to the post-emergence time. Therefore, we think that according to the height of bamboo shoots, we can make reasonable harvest without cutting it, and at the same time, it is easy to grasp when harvesting. In order to explore the best height of bamboo shoots harvesting, we conducted in April 1986 May harvest bamboo height research. Study the square of a typical sample
