一、摘要肉桂乃亚热带樟科常绿乔木,浑身是宝,是珍贵的药用树种。我省自一九六○年引种以来,已近廿年的历史。由于肉桂对气候环境的条件要求较高,故引种区域不大,为了扩大生产,有步骤地引种栽植肉桂,以充分利用自然气候资源。为此要全面地均衡各地气象条件,通过实地观察,综合了各种植区的寒害、物候、生长量与气象因子间的关系,通过了相关计算与方差分析检验,选出了极端最低气温,最冷月平均气温、日平均气温≥20℃积温、年降水量、年平均风速等五个因子。根据所选出的五个气象因子,应用动态聚类分析(Dynamic Clustering Methods)方法,在种植区内,按气候的不同类型,选取了不同种植区的凝聚点,作出不同种植区的区划。其种植区划分为:适宜种植区,较适宜种植区;引种种植区;试引种区等四个不同的种植区。
First, Cinnamon is a subtropical evergreen Lauraceae trees, covered with treasure, is a precious medicinal species. Since its introduction in 1960, our province has nearly 20 years of history. As cinnamon on the climatic and environmental conditions demanding, so the introduction of small areas, in order to expand production, step-by-step introduction of planting cinnamon, in order to make full use of natural climate resources. To this end, it is necessary to balance the meteorological conditions in all areas and observe the relationship between chilling injury, phenology, growth and meteorological factors in various planting areas through field observation. The correlation analysis and analysis of variance test are adopted to select the extreme minimum temperature and the most Average temperature of the cold month, daily average temperature ≥20 ℃ accumulated temperature, annual precipitation, annual average wind speed and other five factors. According to the five meteorological factors selected, dynamic clustering methods are applied to select the condensing points of different planting areas according to the different types of climates in the planting areas to make the division of different planting areas. The planting areas are divided into: suitable planting areas, more suitable planting areas; introduction of planting areas; pilot introduction of planting areas such as four different planting areas.
