| 摘要: |
| 5个树种在从化北部山地试验表明，楝叶吴茱萸能适应当地立地和气候条件，生长略快于西南桦，而比拟赤扬、红椎和深山含笑快的多。径高生长观测结果显示，其生长很有规律，春季随气温升高、湿度增大、降水和蒸发量增大生长逐渐加快为慢生期，但生长逐渐加快；夏季气温高、湿度大、降水大大超过蒸发量，为幼林速生期也是高峰期；秋季气温逐渐下降，湿度和降水逐渐减少、而蒸发量逐渐超过降水量，生长速度中等，但逐月下降；冬季因气候条件主要是温度低不适合幼林生长，因此是生长停顿期也就是休眠或半休眠期。不同气候因子比较，温度是影响生长主要因子，其次是蒸发量，湿度和降水对楝叶吴茱萸生长影响比较小。 |

| Abstract: |
| The paper presented the growth performance of 5 species on mountains area in North Conghua of Guangdong province and the results showed that the Evodia meliaefolia adapted well
to local site and climate and grow little faster than Betula alnoides, but much faster than Alniphyllum fortunei (Hemsl.) Makino, Castanopsis hystrix A.DC, M. maudiae Dunn. The monitor results of height and diameter at breast height showed that its growth had a significant relationship with the season and the climate and the main factor to affect the growth was the temperature, secondary was the evaporation and the last was the humidity and precipitation. The spring was the slow-growing period owing to the risen temperature, humidity, evaporation and precipitation, but the growth speed quicken gradually and reached the maximum in summer, in autumn the speed declined again and stopped in winter. |
