种植密度对金毛狗生长特性与根状茎的影响
Effects of Planting Density on Growth Characteristic and Rhizome of Cibotium barometz
摘要
Abstract
In order to determine optimal planting density for artificial cultivation of rare medicinal plant Cibot-ium barometz,five planting density treatments(1 m×1 m,1 m×1.5 m,1 m×2 m,1.5 m×1.5 m and 1.5 m×2 m)were set under Cunninghamia lanceolata plantations in three experimental points.Effects of planting density on C.barometz growth characteristic(plant height and crown width)and rhizome(fresh weight and yield)were ana-lyzed.Results showed that plant heights,crown widths and rhizome fresh weights generally showed trends of in-crease followed by stabilization as planting density decreasing in three experimental points,all of which general-ly stabilized in≤1 m×1.5 m planting density treatments.Rhizome yields showed trends of increase followed by decrease as planting density decreasing in three experimental points,all of which reached the highest levels in 1 m×1.5 m planting density treatments.In the same planting density treatments,crown widths and rhizome fresh weights were significantly different among three experimental points,indicating which were significantly influenced by environments.Among five planting density treatments,1 m×1.5 m planting density treatment was more suitable for C.barometz growth.关键词
