摘要:猴耳环(Archidendron clypearia(Jack)Nielsen)为含羞草科(Mimosaceae)猴耳环属植物[1-2],乔木,高达10 m,生长于海拔200~1 800 m的溪边、林内或灌丛中,是我国西南部和东南部地区的一个乡土树种,具有很高的药用价值(叶有凉血、消炎功能)。近几年,
The effects of applying N (urea, 46% N), P (phosphate, 12% P205) and K (potassium sulphate, 54% K2 O) fertilizers on the growth performance and biomass yield of 8-month-old Archidendron clypearia seedlings were examined by L9 orthogonal array with 3 replicates in the nursery of Zengcheng Forest Farm of Guangzhou, Guangdong Province. The test seedlings were potted with the subsoil of total N 0.048 4%, total P 0. 151 8% and total K 1. 262 9%, and fertilized at the 2nd and 6th months with the application rates of 0, 10 and 20 mg of N, 0, 20 and 50 mg of P and 0, 10 and 20 mg of K per seedling. The results showed that the diameter at ground level (DGL) , the height and the oven-dried weight biomass of 8-month-old seedlings differed significantly at P = 0.05. The combined application dose of 20 mg N, 20 mg P and 0 mg K per seedling resulted in the best seedling growth and biomass yield. N fertilizer was a significant factor in the growth of DGL and height of A. clypearia seedlings. P fertilizer had no significant effects on both DGL and height, while K fertilizer only affected DGL significantly. Anal- ysis of the leaf and root stoichiometry suggested that N may be the most single limiting nutrient, A. clypearia seed- lings used N more efficiently than they used P.
