油茶林下套种不同中药材的生长节律研究

Study on the growth behavior of different Chinese medicinal materials interplanting under forest of Camellia oleifera

本文研究了油茶林下套种岗梅、毛冬青、五指毛桃、巴戟天及猫尾草等5种中药材在不同月份区间的生长情况和增长量。结果表明:5种中药材的地径、株高(或藤蔓长)生长变化趋势相似,地径、株高(或藤蔓长)均随月份逐渐增大;每种中药材在不同月份区间之间的增长量均具有显著差异;同一月份区间的不同中药材之间的增长量也都具有显著差异;岗梅的地径和株高增长量均在4—6月区间最大,毛冬青和五指毛桃的地径及株高增长量均在7—9月区间最大,巴戟天的藤蔓增长量在4—6月区间最大,猫尾草的株高增长量在7—9月区间最大。因此,应在各种中药材的生长高峰期采取合理追肥等抚育管理措施,促进中药材的生长,使生物量的累积最大化。本研究结果也可为油茶林下套种中药材栽培管理提供可靠的参考依据。

This paper studied the growth behavior and amount of five kinds of traditional Chinese medicine in different months,such as Ilex asprella,Ilex pubescens,Ficus hirta,Morinda officinalis,and Uraria crinita under forest of Camellia oleifera.The results showed that the growth trends of ground diameter or plant height(or vine length)of the five traditional Chinese medicines were similar under forest of Camellia oleifera,and the ground diameter or plant height(or vine length)increased gradually with months.There were significant differences in the growth of each traditional Chinese medicine between different months.There were also significant differences in the growth of different traditional Chinese medicine in the same month.The growth of ground diameter and plant height of Ilex asprella was the largest from April to June,while the growth of ground diameter and plant height of Ilex pubescens and Ficus hirta was the largest from July to September.The growth of vine of Morinda officinalis was the largest from April to June,while the growth of plant height of Uraria crinita was the largest from July to September.Therefore,reasonable topdressing and other tending management measures should be taken at the growth peak of various traditional Chinese medicine to promote the growth of traditional Chinese medicine and maximize the accumulation of biomass.The results of this study can also provide a reliable reference for the cultivation and management of traditional Chinese medicine under forest of Camellia oleifera.
