对贵州野生钩藤生长环境、气候状况、土壤理化特性及蕴藏量进行调查研究,结果表明:贵州野生钩藤资源分布在海拔450～1 250 m范围内,喜温暖、湿润的环境,大部分分布在阴坡,主要生长在林下的坡地,坡度从30～70度不等,多有岩石;伴生植物主要是高大乔木,其次是灌木,还有带刺的蔷薇科藤本植物及喜阴的草本植物;钩藤生长地土壤类型属于壤土,土壤含水量高,有机质含量较低,土壤pH属于酸性范围,碱解氮在缺乏范围,土壤有效磷比较低,土壤速效钾属于丰富水平。野生钩藤资源蕴藏量很少。
The results showed that the resources of Uncaria rhynchophylla in Guizhou were distributed in the range of 450-1 250 m above sea level, hi the warm and humid environment, most of the distribution In the shady slope, the main growth in the forest slope, slope from 30 to 70 degrees, and more rock; associated plants are tall trees, followed by shrubs, and thorns of the Rosaceae vine and hi overcast herbs The soil types belonging to Uncaria macrophylla grew in loamy soil. Soil moisture content was high, soil organic matter content was low, soil pH was in acidity range, available nitrogen was in a low range, soil available phosphorus was low and soil available potassium was rich. Wild Uncaria resource reserves very little.
