- 摘要:
- 以两河口水电站植物护坡工程为背景，以种植紫穗槐的植物卷材为研究对象，把不同施肥梯度和水分配比作为变量因子，探究紫穗槐的生理指标变化趋势，为该区域植物护坡材料的水肥设计提供参考依据。结果表明：当保水剂一定，施肥浓度为12 g?m-2时，紫穗槐叶片中丙二醛含量增加，植物叶片中的过氧化物酶活性减少，可溶性蛋白质含量增多，植物的叶片保水力也最强。当施肥量一定时，保水剂量为10 g?m-2时，可溶性蛋白质含量最少，保水剂量追加到15 g?m-2，此时的可溶性糖含量最多，植物叶片中的丙二醛含量增加，植物叶片保水力也随之增加。
- Abstract:
- The physiological indexes trends of Amorpha fruticosa Linn.under different fertilizer gradients and water ratios at the Lianghekou Hydropower Station plant slope protection engineering system were explored.This investigation provided an effective theoretical basis for the fertilizer and water system designs of plant slope materials in this area.The results showed that when the amount of water-retaining agent was held constant and the concentration of fertilizer was settled as 12 g?m-2，the malondialdehyde(MDA) content in the Amorpha fruticosa leaf was increased，the peroxidase(POD) activity was decreased，soluble protein content was increased，and the capacity of water retention was the highest.When the amount of fertilizer was held constant and the water-retaining agent dose was 10 g?m-2，the amount of soluble protein in the leaf was the lowest.However，when the water-retaining agent dose was increased to 15 g?m-2，the amount of soluble sugar in the leaves was the highest，and both the MDA and water retention capacity was increased.
