【摘要】 鸡骨草主要分布于年最冷月平均温度大于10℃的部分南亚热带和热带地区,呈星散分布。主成分分析表明,温度为影响鸡骨草分布的主导气候因子.分布区内主要植物群落类型为马尾松—桃金娘—芒萁群落.主要土壤类型为赤红壤.鸡骨草茎、叶的生长动态为双峰型。影响其生长的主要外界因子是显度和光照。最后,对如何发展生长提出了一些建议。更多还原

【Abstract】 The study was undertaken to know the geographic distribution the phytocoenological feature and othe ecologic characters of Abrus amitmimas. The result of principal components analysis showed that temperature was the principal factor to determine the distribution of Abrus canioniaisis. It dispersed on 3 certain party of the tropics and the subtropics of China, where the coldest average monthly temperature was over 10℃. It existed in the phytocommunity of Pinus massonana-Rhodomyrtus tomentosa-Dicranopteria dischotoma. In the distributive area, lateritic red earth developed from granite was a principal soil. The growing trend of stem and leaf showed two peak pattern. According to the ecologic. character of Abrus cantoniensis, some suggestions for developing its production were put forward finally.更多还原
