摘要
1989年,在开县国有毛垭林场海拔1000 m处,进行藏柏采种林营造试验。经23年观测,藏柏在该处能正常生长发育。第4年有极少数单株挂果,种子无发芽力;第5年结的种子,发芽率为2%;第6年结的种子发芽率为33%。藏柏平均年生长高为88 cm,胸径为1.1cm,超过当地乡土树种马尾松和杉木的生长量。
In 1989, Cupressus torl afforestation test was carried out by state owned Forest Management Institute at Kai county at an altitude of 1 000 meters. After 23 years of observation and measurement, Cupressus torl can normal grow and develop in the area. In fourth year there had been very few fruit, and the seeds had no germination ability. In fifth year, the seed germination rate was 2%. In sixth year the seed germination rate was 33%. The annual growth of Cupressus torl is as high as 88 cm, and the diameter at breast height is 1.1 cm. The above increments are more than the growth of native tree species such as Chinese fir and Masson pine.
