摘要
为研究海南蒲桃与油茶混交造林的效应,经过几年的经营管理,对其林木生长状况进行了调查,结果显示:海南蒲桃油茶混交林木的林木生长状况,分别大于海南蒲桃、油茶纯林的林木生长状况,树高分别大3.51%、34.00%,胸径粗7.94%、38.76%,树冠大4.55%、27.78%,枝下高大5.41%、21.87%,郁闭度大3.26%、5.56%,单株材积大18.18%、160.00%,蓄积量多31.58%、75.77%。海南蒲桃油茶混交林,林地地表层枯枝落叶物多、林地地表层枯枝落叶物的平均厚度,分别大于海南蒲桃、油茶纯林林地地表层枯枝落叶物的平均厚度的2.12%、16.67%。
After several years of operation and managementofHainan syzygium jambos and camellia mixed afforesta- tion, , we investigated the growth of forest. The result showed： the growthofmixed afforestation, is respective- lygreater thanHainansyzygium jambos, andcamelliapure forests. Tree heights were 3.51% and 34.00 % ; diameter at breast heights were 7.94%and 38.76%; canopies were 4.55%and 27.78%; under branch heights were 5.41%and 21.87 % ; crown densities were 3.26% and 5.56% ; individual volumes were 18.18% and 160.00%; standvolume- swere 31.58% and 75.77 %. The mixed afforestation ofHainan syzygium jambosandcamelliawith more forest litter onwoodland surface, ,whose average thickness of content is higher than respectivetyHainan syzygium jambosand ca- mellia pure forestsby2.12G, 16.67%.
