四川省三个自然保护区箭竹生长与土壤条件关系的研究

RELATION BETWEEN SOIL CONDITIONS AND FOUNTAIN BAMBOO GROWTH IN THREE NATURAL PROTECTIVE AREAS OF SICHUAN

通过对蜂桶寨自然保护区、喇叭河自然保护区、王朗自然保护区的调查研究,结果表明:冷箭竹在酸性、盐基饱和度小、土层深厚而石砾含量少的灰化土类上,生长良好;在石灰土类、土壤碱性、含CaCO_3、土层浅薄夹砾量高的土壤上,开花死亡。

The soil conditions of Feng Tong Zhai, La Ba River and wang Lang natural protective areas were investigated and studied. The results showed that cold fountain bambo could grew well on the acid, low base saturation percentage, thick soil horizon and low gravel content bleached-podzlic soils. It flowered and died on the alkaline, lime, shallow soil horizon and high gravel content calcareous soils.
