摘要
福建晋江深沪湾风口地段由于风沙和盐雾危害严重,导致木麻黄基干林带的营造十分困难。为了筛选出适宜的抗风、耐盐型木麻黄无性系,在晋江深沪湾风口地段进行5个木麻黄无性系造林试验。造林后当年12月对不同木麻黄无性系的生长量和成活率进行调查和分析,结果表明:惠安1号木麻黄无性系的造林成活率(85.65%)最高,其次是粤8(74.80%),而平潭2号(69.72%)的成活率最低,但不同无性系造林成活率差异未达到显著水平;造林后当年木麻黄不同无性系的平均地径、树高的大小顺序均为惠安1>粤501>粤8>粤701>平潭2,惠安1的平均地径(2.19cm)和树高(1.64m)均显著大于其他无性系,而平潭2的平均地径(1.59cm)和树高(1.28m)均最小,平均地径显著小于其他无性系。
Due to the harm by blown sand and salt fog in wind gap of Shenhu Bay of Jinjiang City in Fujian Province,silvi culture of trunk shelterbelt is very difficult. In order to select a suitable wind resistant, salt resistant clonal C. equisetijcblia, afforestation experiments for five clones of C. equisetij（blia were conducted in wind gap of Shenhu Bay of Jinjiang City. The growth and survival rate of different clones of C. equisetijcbZia were analyzed in December of the very year after planting. Re suit shows that survival rate of C. equisetijfolia ＇ Huian 1＇ is the highest （85. 65%）, followed by C. equisetijfolia ＇Yue 8＇ （74.80 %）, the survival rate of C. equisetijcblia ＇ Pingtan 2＇ is the lowest （Gg. 72 %）, but the difference for survival rate of different clones is not significant. The descending order of the mean ground diameter ＆ tree height of different clones of Cast, ring equisetifoblia in the very year after planting is C. equisetijfollia ＇Huian 1＇ 〉 C. equisetijfolia ＇Yue 501＇ 〉 C. eq uisetijCblia ＇ Yue 8＇〉C. equisetifollia ＇ Yue 701 ＇〉C. equisetijCblia ＇ Pingtan 2 ＇ ; the mean diameter （2. 19 cm） and tree height （1. G4 m） of C. equisetij（blia ＇Huian 1＇ are all significantly higher than that of other clones;the mean ground diame ter （1.59 cm） ＆ tree height （1.28 m） of C. equisetifoolia ＇ Pingtan 2＇ are all the smallest;C, equisetifoolia mean diameter of C. equisetijfolia are significantly smaller than that of the other clones.
