养殖废弃物生物有机肥料对藜蒿抗寒性的影响

摘要

Under the condition of low temperature stress, we analyzed the effects of different bio-organic fertilizer treatments on chilling-resistance of Yunnan Artemisia selengensis by determining the leaf electrolytic leakage, soluble sugar content, soluble protein content, proline (Pro) content, malondialdehyde (MDA) content, superoxide dismutase (SOD) activity and peroxidase (POD) activity. The results showed that, compared with those of the pure mineral fertilizer treatment when the application amounts of bio-organic fertilizer increased, contents of Pro, soluble sugar, soluble protein increased and activities of SOD and POD enhanced, but the electrolytic leakage and MDA content decreased, compared with those of the pure mineral fertilizer treatment. In conclusion, bio-organic fertilizer could improve chilling resistance of A. selengensis significantly.%在低温胁迫条件下，分析了不同施肥处理对云南藜蒿叶片电解质渗透率、可溶性糖含量、可溶性蛋白含量、脯氨酸含量（Pro）、丙二醛（MDA）含量及超氧化物歧化酶（SOD）和过氧化物酶（POD）活性的影响。试验结果表明，与纯无机肥料处理相比，施用养殖废弃物生物有机肥料之后，在一定范围内，藜蒿叶片的可溶性糖含量、可溶性蛋白含量、脯氨酸含量、过氧化物酶和超氧化物歧化酶活性随生物有机肥施用量的增加而升高，藜蒿叶片的电解质渗透率、MDA含量随生物有机肥施用量的增加而降低。研究表明，养殖废弃物生物有机肥料可以显著提高藜蒿抗寒性。
