摘要
青钱柳人工林生长特性研究表明,青钱柳生长快,胸径速生期6～16a,树高速生期3～7a,材积速生期6～23a;其连年生长高峰期分别出现在第7a、第5a和第13a,26a以后进入成熟期。在现行造林密度条件下,10～13a生时进行适当的抚育间伐,而20a左右需再次进行间伐,以满足林木对营养空间的充分需要。
The study of cyclocaryapaliurua plantation growth characteristics shows that cyclocaryapaliurua grow fast. Its fast - growing period of Diameter at breast height is 6 to 16 years, and fast - growing period of tree height is 3 to 7 years, and the volume of fast- growing period is 6 - 23 years; and the peak of annual growth would be the7, 5 and 13 years. It would be into maturity after 26 years. It is very necessary for the trees to take full nutrition space that appropriate thinning after 10 - 13 years and effects of thinning again after 20 years under the conditions of the existing afforestation density.
