摘要
【目的】开展毛竹(Phyllostachys edulis)林下套种珍贵树种生长特性及生理生化特性研究,为开展毛竹林下珍贵树种套种及混交林营建提供理论参考。【方法】选择集中连片、立地条件一致的毛竹林,保留竹株1800株·hm^(-2),选择大小一致的红豆树(Ormosia hosiei)、浙江楠(Phoebe chekiangensis)和天竺桂(Cinnamomum japonicum)3种珍贵树种进行套种,种植密度300株·hm^(-2)。种植2年左右,分析测定不同树种生长、叶片光合作用参数、叶绿素含量、可溶性糖含量、可溶性蛋白含量、丙二醛含量以及抗氧化系统活性。【结果】3个树种中长势(地径和苗高)从高到低依次是天竺桂、红豆树和浙江楠;红豆树的Pn、Gs、Ci和Tr均高于其它2个树种;叶片叶绿素a、b、a+b含量和类胡萝卜素质量浓度从高到底依次为红豆树、浙江楠和天竺桂;毛竹林下红豆树POD、CAT活性显著高于浙江楠和天竺桂,SOD活性无显著性差异;浙江楠MDA显著高于红豆树和天竺桂,天竺桂可溶性蛋白和可溶性糖含量最高。【结论】红豆树对毛竹林地环境具有良好的生态适应性,是适合毛竹林下套种的优良珍贵树种。
【Objective】To study the growth characteristics,physiological and biochemical characteristics of the precious tree species under the Phyllostachys edulis forests,and provide theoretical reference for the interplantation of the precious tree species and construction of the mixed forest under the Ph.edulis forests.【Method】The Ph.edulis forests with continuous concentration and consistent site conditions were selected.1800 bamboo plants·hm^(-2) were retained,the same specifications of three precious tree species such as Ormosia hosiei,Phoebe chekiangensis and Cinnamomum japonicum were selected for interplantation,with a planting density of 300 trees·hm^(-2).After planting for about 2 years,the growth data,leaf photosynthesis parameters,chlorophyll content,soluble sugar content,soluble protein content,malondialdehyde content and antioxidant system activity under different treatments were analyzed.【Result】Among the three tree species,the growth(ground diameter and seedling height)from high to low were C.japonicum,O.hosiei and P.chekiangensis.The Pn,Gs,Ci and Tr of O.hosiei were higher than those of the other two species.The contents of chlorophyll a,b,a+b in leaves and the concentration of carotenoid quality from high to low were O.hosiei,P.chekiangensis and C.japonicum.The activities of POD and CAT in O.hosiei were significantly higher than those in P.chekiangensis and C.japonicum,but no significant difference in SOD activity was observed.MDA of P.chekiangensis was significantly higher than that of O.hosiei and C.japonicum,and the contents of soluble protein and soluble sugar in C.japonicum were the highest.【Conclusion】O.hosiei has good ecological adaptability to the environment of the Ph.edulis forests and is an excellent precious tree species suitable for interplantation under the Ph.edulis forests.
