为了迅速发展毛竹生产,我县从1978年起,从广西柳州引进毛竹种子进行育苗,共培育实生苗十四万株(其中实生苗八万、分殖苗四万、小母竹二万)。1980年选择了四个立地条件不同的山场,营造了122亩毛竹试验林,除在李枚山区因造林工作粗放,成活率较低外,其他三地造林成活率均在96％以上。据调查,造林当年新竹高100Cm。第二年每棵发新竹22株,最多41株;竹高172Cm,最高255Cm,地径1.2Cm,最粗1.8Cm;竹鞭长176Cm,且四出横生,遍布林地,长势旺盛。现将其造林及管理技术简介如下:
In order to rapidly develop the production of bamboo, our county has introduced moso bamboo seedlings from Liuzhou, Guangxi in 1978 for a total of 140,000 seedlings (including 80,000 seedlings, 40,000 seedlings and 20,000 small parent bamboo). In 1980, four mountain mounds with different site conditions were selected to create 122 mu bamboo forest. In addition to the extensive afforestation and low survival rate in Li Heshan, the afforestation survival rates of the other three areas were above 96%. According to the survey, afforestation year Hsinchu high 100Cm. In the second year, 22 new plants were made in each of them, with a maximum of 41 strains. The height of bamboo was 172Cm, the highest was 255Cm, the diameter was 1.2Cm and the thickness was 1.8Cm. The rhizome was 176Cm long. Now its afforestation and management techniques are as follows:
