| 摘 要： | 本文研究了不同立地条件麻疯树生殖年龄的问题。研究表明。土壤厚度和群落环境是影响林分生殖年龄的主要因素,前者影响了土壤水分和营养元素供给,后者影响了更新个体的光能利用。表明,生殖是一个营养问题,是营养生长到一定阶段的产物,受到个体发育的立地条件调控。还提出了麻疯树林分促成结实的管理措施。

| Abstract: | In this paper,researches were conducted on the problem of growth and reproductive age of Jatropha curcas forests in different plot conditions.Results indicated that soil depth and community environment were the main factors affecting the reproductive age and growth.The formers influenced the availability of soil moisture and nutritious elements,and the latter affected the reproduction and growth because the growth went short of light availability.These demonstrated that reproduction was a nutrition problem ... |
