2种营林模式下毛竹磷含量变化的研究

Changes of Phosphorus Content in Moso Bamboo Under Two Forest Management Modes

采取钼锑抗比色法对毛竹根、枝、叶、皮的含量进行试验分析及差异性对比。结果表明:从不同营林模式上看,毛竹植株叶、根、皮的磷含量表现为ZC(毛竹纯林)>ZS(毛竹杉木混交林),而枝的磷含量表现为ZS(毛竹杉木混交林)>ZC(毛竹纯林);从不同坡位上看,毛竹植株磷含量表现为下坡>中坡>上坡;从不同月份上看,毛竹植株枝、根、叶、皮的磷含量表现为8月>10月>12月>5月>3月。

The contents of roots,branches,leaves and skins of Moso bamboo were analyzed and compared by molybdenum antimony anti colorimetry.The results showed that the phosphorus content of leaves,roots and bark of Moso bamboo was ZC>ZS,while the phosphorus content of branches was ZS>ZC;From different slope positions,the phosphorus content of Moso bamboo plants showed downhill>middle slope>upslope;In different months,the phosphorus content of branches,roots,leaves and skins of Moso bamboo was 8>10>12>5>3.
