摘要
檫树人工林生长特性研究表明,檫树在2年生前生长较为缓慢,2年生后生长迅速,其树高、胸径、材积连年生长高峰期分别出现在第4年、第3年和第8年,数量成熟期为20年。在现行造林密度条件下,6～8年、16年生时进行适当的间伐是非常必要的,而16年左右需再次进行适当的抚育间伐,以满足林木对营养空间的充分利用。如在培育过程中,无采取任何调节林分密度措施,则16年生后可采伐利用。
The study of growth characterization of Sassafras tsumu plantation indicated that： The Sassafras tsumu plantation grew slowly in started 2 years, and rapidly after 2 years, the growth peak periods of height, diameter breast height and current annual increments of volume emerged in the 4th, 3rd, and 8th year, respecially, quantitative mature period was 20 years. It is very necessary for intermediate cutting in the 6-8th year, 16th year in current plantation density, and once more in the 16th year to meet full use of nutritional space for timbers. If without taking any measures to regulate stand density in cultivating process, the timbers can be harvested and used after 16 years.
