摘  要:
采用"311-A"最优混合设计,研究了不同氮、 磷、 钾配比施肥对澳洲茶树幼林地径、 株高、 枝叶总重、侧枝重、 侧枝占比的影响.结果表明,氮有利于提高澳洲茶树地径、 株高、 枝叶总重、 侧枝占比.纯氮、 纯磷、纯钾的用量分别为71.4g/株、17.2g/株和26.7g/株,此时的侧枝重达到最大为1.36kg/株,相应的地径为3.30cm、 株高为268.3cm、 枝叶总重为1.97kg/株,侧枝占比为63.2%,此时澳洲茶树幼林的氮、 磷、 钾施肥配比为1︰0.24︰0.37.

摘  要:
Adopting the "311-A" optimum compound design, the effects of nitrogen, phosphorus and potassium on ground diameter, plant height, total weight of branches and leaves, weight of lateral branch and leaves, per-cent of lateral branch of young Melaleuca alternifolia were studied. The results indicated that nitrogen was benefit for the increase of ground diameter, plant height, total weight of branches and leaves, weight of lateral branch and leaves, percent of lateral branch. Applying pure nitrogen, pure phosphorus and pure potassium of 71. 4g, 17. 2g and 26. 7g per plant respectively, the corresponding weight of lateral branch and leaves, total weight of branches and leaves, ground diameter, plant height, percent of lateral branch were 1. 36 kg per plant, 1. 97 kg per plant, 3. 30cm per plant, 268. 3cm and 63. 2% per plant respectively. therefore, the optimal fertilizer for-mula was 1. 0 ︰ 0. 24 ︰ 0. 37.
