为发掘更好的彩叶观赏树种蓝果树种质资源和进一步开发利用及保存，采用400 m2的标准样法对黔中地区11个县(市、区)的蓝果树种质资源进行调查，观察土壤颜色、测量土层厚度和海拔；测量树高、胸径、冠幅、枝下高及代表植株的5～12片叶的叶长、叶宽，并观察其叶形和叶色；记录样地内所有伴生植物的种类。结果表明：蓝果树生长的土壤多为酸性的黄壤，土层厚度在24～212 cm 之间，海拔在1021～1439 m 之间。平均叶长在8.1～12.7 cm 之间，平均叶宽在3.6～6.2 cm 之间，叶色方面主要变化有绿色间紫红色或红色、铁锈红色、绿色。21个样地中蓝果树的平均年龄多在10～20年，多数胸径小于10 cm，平均胸径最大的30.9 cm，其次为19.0 cm。21个样地中均有的伴生植物都为酸性土壤的指示性植物。初步查清了黔中地区蓝果树种质资源，为发掘更好的蓝果树种质资源和良种选育、进一步开发利用及保存提供基础参考。

This research to explore the better germplasm of Nyssa sinensis of color leafed ornamental trees and the further exploitate and preserve it.The method of standard sample of 400 m2 was carried out to investigate the Nyssa sinensis germplasm resources in 11 county (city, area) of central Guizhou area.The soil color was observed,and the soil thickness and altitude also was measured.The tree height, diameter at breast height, crown breadth and under branch height were Measured,and the leaf length and width of 5 ~ 12 leaves of the representative plants were Measured, its leaf shape and leaf color were observed.All the associated plant species were recorded in sample plots. The results showed that:The Nyssa sinensis growing soil for acidic yellow soil, soil layer thickness in the range of 24 ~ 212 cm, altitude of between 1 021 ~ 1 439 m.The average leaf length in 8.1 ~ 12.7 cm, average leaf width in 3.6 ~ 6.2 cm.The main changes of leaf color is green room purplish red or red, rust red or green.The average age of Nyssa sinensis in 10 ~ 20 years in 21 samples, the majority of diameter less than 10cm, the average diameter Max 30.9 cm, followed by 19.0 cm.some associated plants in 21 sample are indicative plants of acid soil.The study preliminary investigated Nyssa sinensis germplasm resources in central Guizhou area.This research provide a basis for reference on exploring the better Nyssa sinensis germplasm resources and breeding, further development and utilization and conservation.
