摘要:采集了云南省10个翠柏主要分布区的土壤样品并进行营养成分分析。结果表明,翠柏分布区土壤以红壤为主,酸度从极酸到偏酸性,有机质含量较丰富,全N稍缺,全K普遍缺乏,全P和速效P严重缺乏,碱解N较丰富,速效K部分地区丰富,部分地区缺乏,交换性钙和交换性镁变化大,有的地区缺乏,有的地区丰富,有效B处于正常,阳离子交换量大多数地区是较差的。相关分析结果表明,树木的胸径、树高和材积与土壤速效N、速效P、有机质呈极显著正相关,与全P和全N呈显著正相关。
The soil samples of Calocedrus macrolepis' s distributing area in Yunnan province were collected and analyzed. The results showed that the soil in distributing area was red earth,soil p H was at acid to meta acid,soil organic matters was abundant,total N slightly lacked,total K at large lacked,total P and quick available P was severity lack,alkali-hydrolyzable N was rich,available K in parts was rich and parts was lack,exchangeable Ca and Mg had great variation,and part area was rich and part was lack,available B was in normal range,CEC in mostly part was worse. The correlation analysis showed that diameter at breast height,height and volume was positively correlated with organic matters,alkali-hydrolyzable N and available P,evident positive with total N and total P.
