摘要
为探讨不同配方施肥对樟树(Cinnamomum camphora)无性系人工林生长的影响,采用正交设计进行施肥试验,为樟树人工林建立合理的施肥制度提供理论依据和技术支撑。结果显示,施肥处理对樟树无性系人工林的株高、地上部分鲜重和枝叶鲜重影响极显著,其中处理7的地上部分鲜重较对照提高了47.16%,枝叶鲜重提高了59.09%;5种养分元素对枝叶鲜重的影响为N>P>Zn>B>K,最优组合为N2P3K4B4Zn2,即每株施108.70 g尿素+555.56 g钙镁磷肥+250 g氯化钾+54.55 g硼砂+8.70 g硫酸锌。
To explore effects of different formula fertilizations on growth of Cinnamomum camphora clonal plantation, fertilization experiment with orthogonal design was made, which could provide theoritical evidence and technical support for suitable fertilization of C. camphora plantation. Results showed that effects of fertilization treatments on plant height, aboveground fresh weight and fresh weight of branches and leaves in C. camphora clonal plantation were extremely significant. Among them, aboveground fresh weight of treatment 7 increased by 47.16%, and fresh weight of branches and leaves increased by 59.09%. The order of effects of five elements on fresh weight of branches and leaves was N > P > Zn > B > K, and the optimal combination was N2P3K4B4Zn2,which was 108.70 g urea + 555.56 g calcium magnesium phosphate + 250 g potassium chloride + 54.55 g borax +8.70 g zinc sulfate per plant.
