Effects of Different Seedling Cultivation Methods on the Growth of Castanopsis eyrei Champ.ex Benth.Tutch
In December 2023,field seeding(T1 treatment),root cutting and root transplanting(T2 treatment),light substrate container seeding(T3 treatment),root cutting and root transplanting(T4 treatment)of Castanopsis eyrei Champ.ex Benth.Tutch seedlings were tested for growth,root,fresh weight and seedling formation rate.The re-sults indicate that the differences in seedling height,ground diameter,main root length,primary lateral root,aboveground fresh weight,underground fresh weight,total fresh weight,root crown ratio,and survival rate among the four treatments of Castanopsis eyrei Champ.ex Benth.Tutch seedlings were significant(P＜0.05).The differ-ence in height to diameter ratio was not significant(P＞0.05);The average seedling height,ground diameter,aboveground fresh weight,underground fresh weight,and total fresh weight of Castanopsis eyrei Champ.ex Benth.Tutch seedlings treated with T3 and T4 were all higher than the total average.Comprehensive comparative analy-sis shows that seedlings of Castanopsis eyrei Champ.ex Benth.Tutch cultivated with T3 and T4 treatments grew better.
