| 摘 要： | 采用田间试验,研究了钾肥对兰州百合开花期叶片抗旱生理指标的影响.结果表明,施钾量在0~150kg/hm2范围内,随着钾肥施入量的增加,丙二醛含量降低,可溶性糖含量、过氧化氢酶活性和脯氨酸含量增加,但施钾量超过150 kg/hm2时,丙二醛含量略有上升,可溶性糖含量、过氧化氢酶活性和脯氨酸含量有所下降.在施氮量225 kg/hm2和施磷量150 kg/hm2的不打顶处理下叶片丙二醛含量低于其它处理,脯氨酸含量、过氧化氢酶活性和可溶性糖含量高于其它处理;且在施氮量225 kg/hm2、施磷量150 kg/hm2和施钾量150 kg/hm2的不打顶处理下,丙二醛含量出现最小值,脯氨酸含量、过氧化氢酶活性和可溶性糖含量呈现最高值.

| Abstract: | A sequential field trial of semi-arid sloping tillage was conducted to study the effect of potassium fertilizer on drought resistance physiological characteristics in leaf of Lilium davidii var.unicolor during the period of florescence with the random block design of three factors.The results showed that the accumulation of MDA decreased.The content of soluble sugar,CAT activity and free proline increased with the increasing of potassium fertilizer application within 0 to 150 kg/hm2.Potassium fertilizer app... |
