摘　　要： 根据四个样地55株样木565个样品材料,本文报道思茅松器官旱季的含水量.①思茅松器官含水量是:树干<根颈<枝<根系<叶<果.但随器官部位差异而变化.②树干、枝、根系的含水量均是基部低梢部高.③相同器官年龄大的部位含水量低而年龄小的部位含水量高. The water content of organs of Pinus kesiya var langbianensis during dry seaon is studied based on 565 samples of 55 trees. The results are as follows. 1. The allocation of water content to organs is generally: stem < root neck < branch < root system < needle < cone. 2. In general, the water content of stems, branches and roots is low at their basis and high at their tops / tips. 3. The water content decreases as the organs become old.
