| 摘 要： | 随着全球气候变化加剧,增强植物抗逆性日益成为一个重要的研究课题.施肥作为速生丰产人工林培育的主要手段,其对竹类植物的抗寒性影响方面的研究甚少.本实验以慈竹为材料,研究低温胁迫下不同磷肥施用水平对其抗寒性的影响,旨在确定提高慈竹抗寒性的最佳施肥水平,以期为应对全球气候变化的极端天气提供参考.结果表明,随着温度的降低,慈竹各抗寒生理指标呈现规律性变化,磷肥施用量对慈竹抗寒性有明显的影响.在氮、钾肥施用量适中时,施用低水平磷肥(1.25kg丛·年)更有利于提高慈竹的抗寒性.

| Abstract: | With the global climate change,it becomes more and more important to improve the stress resistance of plants.Applying fertilizer is the main measure to promote the growth of man-made forest,but studies about its effect on cold-resistance of bamboo is rather scarce.Neosincalamus affinis was used in this experiment to investigate the influence of Phosphorus application amount on its cold-resistance.The experiment aimed to establish a perfect application amount to enhance the cold-resistance of Neosincalamus a... |
