配方施肥对澳洲茶树萌芽林生长性状的影响研究
|
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萌芽林地径、株高、枝叶总重、侧枝重的影响。结果表明:氮、磷、钾的合理配比有利于提高澳洲茶树萌芽林地径、株高、枝叶总重和侧枝重。纯氮、纯磷、纯钾的用量分别为99.2、32.6和96.7 g/株时,侧枝重达到最大,为3.23 kg/株,相应的地径为4.7 cm、株高为308.1 cm、枝叶总重为4.85 kg/株,此时澳洲茶树萌芽林的氮、磷、钾施肥配比为1∶0.33∶0.97。
The effects of nitrogen, phosphorus and potassium fertilizers on ground diameter, plant height,total weight of branches and leaves, weight of branches and leaves of Melaleuca alternifolia sprout forest were analyzed by using " 311-A" optimum compound design. The results indicated that the reasonable mix of nitrogen, phosphorus and potassium fertilizer increased the ground diameter, plant height, total weight of branches and leaves, weight of branches and leaves. When nitrogen, phosphorus and potassium fertilizer were dressed at a respective rate of 99.2, 32.6 and 96.7 g per plant, the branches of the plant were the highest in weight, up to 3.23 kg/plant, and the plant grew 4.7 cm in ground diameter and308.1 cm in plant height, and produced a total weight of branches and leaves of 4.85 kg/plant. The mix ratio of nitrogen, phosphorus and potassium fertilizers was 1∶0.33∶0.97.
