摘要
选取漳州地区2014年龙眼树林下种植的铁皮石斛作为主要的研究对象,利用其生长发育状况的试验观测资料及其同期平行观测的龙眼树林下的气象数据资料(主要为气温、光合有效辐射、相对湿度),分析龙眼树林下铁皮石斛的生长情况,研究气象条件对树林下铁皮石斛生长的影响。结果表明气象条件与铁皮石斛的茎生长有显著的相关性,其中气温(包括日平均气温、日平均最高气温、日平均最低气温)对树林下铁皮石斛的茎生长影响最大。在日平均气温27~30℃、日最高气温约32℃和日最低气温约25℃的条件下,铁皮石斛的茎生长较快。通过回归分析建立铁皮石斛茎增长量与气象条件间的数学模拟模型,借以了解漳州地区树林下铁皮石斛的生长。
Dendrobium candidum grown in longan forest in Zhangzhou area in 2014 was selected as the main object of study. Based on the observation data of its growth and development and the meteorological data of longan forest in the same period（ mainly temperature,photosynthetically active radiation,relative humidity）. The growth of Dendrobium officinale in longan forest was analyzed,and the effects of meteorological conditions on the growth of Dendrobium candidum were studied. The results showed that the meteorological conditions had significant correlation with the stems growth of Dendrobium officinale. The temperature（ including daily average temperature,average daily maximum temperature and average daily minimum temperature） had the greatest influence on stem growth of Dendrobium officinale. Dendrobium officinale grew faster with daily average temperature of 27 - 30 ℃,daily maximum temperature of about 32 ℃ and daily minimum temperature of about 25 ℃. The mathematical model of stem growth and meteorological conditions of Dendrobium officinale was established by regression analysis to understand the growth of Dendrobium officinale in Zhangzhou area.
