我区自1964年开始,采用移竹造林的方法,先后发展毛竹18000亩,从造林成活率来看,几乎都在95%以上,但抽鞭产竹只有70%左右,还有30%左右的母竹不能产竹。为了弄清这些母竹不能产竹的原因,以便更好地指导今后造林生产,我们曾于11月7日在宜兴县大贤岭林场虬山岭上区一号界,挖取16株1975年栽植的(栽时母竹年龄1—2年生)而至今从未产竹的母竹进行竹鞭解剖分析。现将结果整理如下: 一、解剖的方法和步骤 首先通过观察母竹周围是否产竹,以确定要解剖的不育母竹,然后用山锄挖去
Since 1964, our district has adopted the method of shifting bamboo and afforestation, and has successively developed 18,000 mu of bamboos. According to the survival rate of afforestation, almost all of them are above 95%, but only about 70% of bamboos are whipped, and about 30% Mother bamboo can not produce bamboo. In order to clarify the reasons why these mother bamboo can not produce bamboo so as to better guide future afforestation production, we dug 16 plants planted in 1975 on the 1st sector of Dalingshan District, Daxianling Forest Farm, Yixing County (Planted at the age of 1-2 years of mother bamboo) has never been born bamboo bamboo whip anatomical analysis. Now the results are organized as follows: First, the anatomical methods and steps First of all, by observing whether the bamboo around the mother bamboo to determine the anatomical sterile mother bamboo, and then dug with a mountain hoe
