摘　　要：在云南元谋县的干热河谷引种了9个木麻黄种和1个无性系,并比较它们的生长情况。结果表明:短枝木麻黄、细枝木麻黄和肥木木麻黄的树高生长最好,粗枝木麻黄的树高生长最差。造林1年和2年后都以短枝木麻黄的保存率最高,轮生木麻黄的保存率最低。综合树高及保存率两个生长指标,短枝木麻黄可作为云南干热河谷造林树种进行进一步推广试验。木麻黄接种Frankia菌后造林的试验结果表明,接种Frankia固氮菌后对木麻黄树高生长有极显著影响。To rich tree genetic resources in hot dry river valley region, the nine species and one clone of Casuarina were introduced to Yuanmou county, Yunnan province in 2003. The two field trials were established on July 8, 2007, the Casuarina introduction trial with six Casuarina species and one clone AS, and the inoculation Frankia trial for Casuarina cunnighamiana with four Frankia inoculation treatments and one control. A complete randomized block design was employed in the two trials, respectively with four replicates and 30 trees per seedlot in the introduction trial, and four replicates and 20 trees per Frankia treatment in the inoculating Frankia trial. At one and two years after planting, tree heights and survival percentages of Casuarina were recorded for the two field trials. The results showed that Casuarina equisetifolia, C. cunninghamiana and C. obesa gained the best height growth, and C. glauca presented poorest height growth in the six species and one clone in the field trials. Casuarina equisetifolia could be applied to hot-dry valley for further extensive use according to the field experimental results. Based on the experimental results, C. cunninghamiana inoculated with some Frankia isolates showed very significant differences in tree height.
