| 摘 要： | 目的：掌握木香生长发育特性,为木香高产栽培进行合理促控提供依据。方法：通过田间试验,在木香不同生长期进行动态采样调查测定。结果：根据木香各器官生长变化及干物质积累特点,分析了木香的生育时期。木香的生长参数,即相对生长率、净同化率、叶面积指数、叶面积比率、比叶面积、作物生长率等都是随着生育进程而变化的。木香整个生育期干物质积累规律为第一年慢,第二年和第三年都较快,生长中心由叶逐渐转移至块根。结论：准确掌握木香生育时期及其生长参数的变化规律有利于在生产中采取适宜的栽培措施,达到优质高产。

| Abstract: | Objective: To explore the growth characteristics of Aucklandia lappa Decne., and provide basis for standardized cultivation. Method: Plant samples were collected and investigated periodically. Result: According to the growth of different parts and the characteristics of dry substance accumulation of Aucklandia lappa Decne., the growth period was analyzed. The growth parameters of Aucklandia lappa Decne. relative growth rate, net assimilation rate, leaf area index, leaf area ratio, specific leaf area and crop growth rate, all change with the growth process. The accumulation of dry matter was slow in the first year, fast in the second year and the third year, and the growth center was gradually transferred from leaves to roots. Conclusion: Cultivation technologies of Aucklandia lappa Decne. and the relevant management methods could be established according to the growth of different parts of Aucklandia lappa Decne. |
