摘要
采用"311-A"最优混合设计,研究氮、磷、钾肥对澳洲茶树枝叶总重、侧枝重、含油率和产油量的影响。结果表明:氮有利于提高澳洲茶树枝叶总重、侧枝重和产油量;氮、磷、钾的用量分别为74.3、18.1和23.1g/株,相应的枝叶总重为2.12 kg/株、侧枝重1.36 kg/株、含油率1.71%、产油量0.023 3 kg/株;氮、磷、钾最佳的施肥配方质量比为1∶0.24∶0.31。
Melaleuca alternifolia was treated with fertilizers by using the ＂311-A＂ optimum mixed design to analyze the effects of nitrogen, phosphorus and potassium on the total weight of branches and leaves, weight of lateral branch and leaves, oil content ratio and oil production of M. cdternifolia. The results indicated that nitrogen was conducive to an increase in total weight of branches and leaves, weight of lateral branch and leaves and oil production. Treated with pure nitrogen, pure phosphorus and pure potassium at a rate of 74.3, 18.1 and 23.1g per plant, respectively, M. ahernifolia produced 2.12 kg/plant of a total weight of branches and leaves, 1.36 kg/plant of weight of lateral branch and leaves, 1.71% of oil content and 0.0233 kg/plant of oil yield. The optimal fertilizer formula was 1.0 ： 0.24 ： 0.31 for NPK.
