摘要
通过42个木麻黄无性系在广东汕头的对比试验,结果表明:各无性系幼林生长与苗期的相关性较差,苗期选择不可靠;各无性系树高、冠幅和保存率都具极显著差异,利用树高、冠幅和保存率对无性系进行综合选择是可行的;运用加权评分法筛选出东山2、莆20、东山短、抗1、88、抗3、平5、C6、701、南山7等生长迅速且适应当地气候条件的优良无性系。
Comparative experiments were conducted among 42 clones of Casuarina equisetifolia in Shantou of Guangdong. The results show that relativity of young forest with seedling in the growth is poor. There are highly significant differences in all traits between tree heights, range of tree crown, preservation ratio. It is feasible to select better clones by colligati ag the traits. The better clones of Dongshan 2, Pu 20, Dongshanduan, Kang 1,88, Kang 3, Ping 5, C 6,701, and Nanshan 7 have been selected. Those clones are the excellent material for building and restoring large-scale coastal protection forest in Guangdong province.
