摘　　要：为了探索武夷桦在不同环境下的生长规律,找到其最适种植方式,为种植和推广该树种提供依据,本研究进行不同种植密度下的武夷桦育苗及引种栽培试验,研究武夷桦的育苗和引种栽培技术。结果表明,武夷桦的生长发育受到温度和水分的影响,最低气温对武夷桦生长速度的影响较大;种植第1年,种植密度为1 500株/hm^(2)(实验组B)的武夷桦林分平均高较高,种植第2年,种植密度为1 200株/hm^(2)(实验组A)的武夷桦林分平均高较高;种植密度为1 800株/hm^(2)(实验组C)时,武夷桦林分树高的高低变化差异较明显,而种植密度为1 200株/hm^(2)(实验组A)时武夷桦林分树高的高低变化差异不大;武夷桦可在研究区域大面积推广种植。In order to explore the growth patterns of Betula wuyiensis in different environments,find the most suitable planting method,and provide a basis for planting and promoting this tree species,this study conducted seedling cultivation and introduction cultivation experiments of Betula wuyiensis under different planting densities,and studied the seedling cultivation and introduction cultivation techniques of Betula wuyiensis.The results shoued that the growth and development of Betula wuyiensis are influenced by temperature and moisture,with the lowest temperature had a significant impact on the growth rate of Betula wuyiensis;in the first year of planting,the average height of Betula wuyiensis with a planting density of 1500 plants/hm^(2)(experimental group B)was higher,while in the second year of planting,the average height of Betula wuyiensis with a planting density of 1200 plants/hm^(2)(experimental group A)was higher;when the planting density is 1800 plants/hm^(2)(experimental group C),there is a significant difference in the height variation of the Betula wuyiensis stand,while when the planting density is 1200 plants/hm^(2)(experimental group A),there is not much difference in the height variation of the Betula wuyiensis stand,Betula wuyiensis can be widely promoted and planted in the research area.
