摘要
试验结果表明:随留茬高度增加,多年生黑麦草的过氧化氢酶活性增加,硝酸还原酶活性降低,随生育进程,硝酸还原酶呈高-低-高的动态变化趋势。各植物生长延缓剂均可提高多年生黑麦草的硝酸还原酶和过氧化氢酶的活性,增强其对氮素的利用率和对活性氧的清除能力。
The nitric acid dexidze enzyme activity of perennial ryegrass decreased and meanwhile catalase activity increased with stubble increasing.The activity of nitric acid dexidze enzyme and catalase in perennial ryegrass were increased by plant growth retardants.
