南酸枣天然林生长规律研究

对南酸枣天然及人工状态下的生长过程研究表明 ,南酸枣天然林胸径生长高峰期在 15年生左右、树高生长高峰期在15～ 2 0年生 ,材积生长高峰期在 2 0年生左右 ,南酸枣人工林的胸径、树高生长峰值比天然林的出现时间早 8～ 10a,峰值大。经过人工培育 ,南酸枣具有更强的速生性 ,人工造林效果好 ,在森林分类经营中具有广阔的发展前景

Studies on the Growth Laws of Choerosponsias axillaries Natural Forests

The study shows that peak dbh growth stage of Choerosponsias axillaries natural forests is around the age of 15,the peak height growth stage is around the age of 15～20,and the peak volume growth stage is around the age of 20.The peak growth value emergence time of dbh and height of C.Axillaries plantations is 8～10 years earlier than that of C.Axillaries natural forests,the peak value of the plantations is high.C.Axillaries possesses stronger fast growing property through artificial culture.The artificial afforestation effects of C.Axillaries are good,and C.Axillaries possesses broad development prospects in the forest classification management.
