7种樟科植物生长、生理与养分积累的特性
Comprehensive Evaluation of Growth,Physiological and Nutrient Accumulation Characteristics of Seven Lauraceae Species
摘要
Abstract
The aim is to better understand the ecological characteristics of Lauraceae plants,select the species suitable for cultivation and popularization in southwest Guangxi.In this study,seeds of 7 species of Lauraceae from 3 genera(Machilus,Beilschmiedia,Cinnamomum)were collected,and the growth,physiological and nutrient accumulation characteristics of their 4-year-old plants were studied and evaluated after seeding in Nanning.The results showed that:(1)the plant height and ground diameter of B.yaanica and B.fordii were the largest,and the seedling elongation and thickening of Beilschmiedia were better than those of Machilus and Cinnamomum,while the height-diameter ratio of Machilus was smaller and the overall growth was more balanced.(2)M.thunbergii had the largest single leaf area and the strongest instantaneous photosynthesis.The overall leaf growth and photosynthetic characteristics of Machilus were better than those of Beilschmiedia and Cinnamomum(the overall antioxidant enzyme activity of the seedlings was higher).The content of MDA(membrane peroxidation degree)was lower in the Beilschmiedia seedlings.(3)The overall nitrogen,phosphorus and potassium nutrient accumulation of Machilus spp.seedlings was better.M.rufipes was limited by nitrogen,M.thunbergii,M.minkweiensis and B.yaanica were limited by phosphorus,but other species were not limited by nitrogen,phosphorus and potassium.(4)Through membership degree analysis,it can be seen that M.thunbergii had the best comprehensive performance(average membership of 0.625),followed by B.yaanica and M.minkweiensis.C.saxatile and M.rufipes had the worst comprehensive performance(average membership of 0.302 and 0.292,respectively).In summary,M.thunbergii is most suitable for the promotion in Nanning,and attention should be paid to the supplement of nitrogen and phosphorus elements and the guarantee of water and fertilizer conditions during cultivation,followed by B.yaanica and M.minkweiensis,while the cultivation conditions and cultivation methods of C.saxatile and M.rufipes need to be optimized.关键词
