不同土壤类型对毛竹林生长的影响研究

Influence of Soil Type on the Growth of Phyllostachys heterocycla cv pubescens Forest

研究了福建省常见的7种土壤类型(红壤、黄红壤、黄壤、紫色土、红土、黄泥土、水稻土)对毛竹林出笋数、新竹成竹率和新竹胸径的影响。结果显示,毛竹林出笋数及新竹胸径在不同土壤类型间均存在极显著差异,新竹成竹率在不同土壤类型处理间的差异不显著。研究结果认为,在毛竹造林时应优先选择退耕的农地,即耕作土壤黄泥土和红土。

The influences of 7 types of soils （red soil, yellowish red soil, yellow soil, purple soil, red clay, yellow clay and paddy soil） commonly seen in Fujian Province on the number of shoots, adult bamboo preserved rate and DBH of new culms in Phyllostachys heterocycla cv pubescens forest were studied. The results showed that there were significant differences in number of shoots and DBH of new culms in Ph. heterocycla cv pubescens growing in different types of soils, while the adult bamboo preserved rate showed insignificant variance for different types of soils. The study results indicated that the agricultural land conversion should be in priority to establish Ph. heterocycla cvpubescens, i.e., with yellow clay and red clay.
