| 摘 要： | 在田间试验条件下,研究了不同钾钙镁营养条件下香蕉生长和叶片生理特性的变化。结果表明,适量增施K、Ca及Mg肥有利于香蕉植株的生长发育,有利于为香蕉果实的生长发育提供良好的物质基础。且能有效促进叶片叶绿素的合成,提高叶片净光合速率,从而有效提高叶片光合作用能力。适量增施K、Mg肥能降低叶片抗氧化酶活性及膜脂过氧化强度,从而有效延缓叶片衰老。在广东高州市香蕉主产区,钾钙镁适宜用量为K2O 990、Mg 37.5、Ca 90.0 kg/hm2。 |

| Abstract: | A field experiment was conducted to investigate the effects of potassium,calcium,and magnesium doses on the growth of banana plant and the leaf physiology characteristics.The results showed that it promoted the growth of banana plant,and offered the good material base for growth of banana fruit effectly with proper K,Ca and Mg in banana plantation.And it promoted the formation of chlorophyll effectively,enhanced the net photosynthesis rate,so improved the photosynthesis ability of leaf effectively.It debase... |
