Effect of Formula Fertilization on Yield and Oil Content of Cinnamomum camphoravar.linaloolifera

Adopting the 311-A optimum compound design,the effects of nitrogen,phosphorus and potassium on shoot yield and oil content of Cinnamomum camphora var.linaloolifera were studied.The results indicated that nitrogen was benefit for the increase of shoot yield,whereas potassium was helpful for the increase of oil rate.Applying nitrogen,phosphorus and potassium of 115.67 g,33.19 g and 133.40 g per tree respectively,the corresponding shoot yield and oil content ratio were 2.67 kg per tree and 1.43 % respectively.It was therefore concluded that the optimal fertilizer formula was 1︰0.29︰1.15.
