摘要
对滇中地区9县(市)16个点野生何首乌的生境进行了调查。结果表明:何首乌广泛分布于滇中地区海拔1400~2100 m及光照强度5000~10000 lx的疏林、灌木丛或路边、田边、土坎上;适于生长在光照充足、空气湿度较大、土壤有机质含量高、质地疏松、保水和排水性良好、土层深厚、微酸到中性的壤土或砂壤土上;稀疏灌木林伴生能保障何首乌正常生长对光照的需求。
The habitats of wild Polygonum multiflorum Thunb.at 16 locations of 9 counties （cities） in the central region of Yunnan province were investigated .The results showed that Polygonum multiflorum was widely distributed in the sparse forests , shrubs, or on the roadsides, field sides and land ridges with the elevation of 1400~2100 m and the light intensity of 5000~10000 lx in central Yunnan;the suitable conditions for the growth of this plant were sufficient sunshine , high air humidity , and slightly a-cidic^neutral loam or sandy loam with high organic matter content , loose texture , good water -holding and drainage capacity , thick soil layer;the accompanying sparse shrubbery could guarantee the sunshine demand for the normal growth of Polygonum multi-florum.
