摘要
以早熟禾草坪为试材,研究了不同氮磷施用量对其色素含量及外观质量的影响。结果表明:氮磷可以提高草坪叶片内叶绿素a、b含量,其中41.90kg/hm2处理提高效果最佳,与对照相比差异显著,37.71kg/hm2处理提高效果最差,与对照间无显著差异;41.90kg/hm2处理除8月份外均可提高类胡萝卜素含量,6、10月显著高于对照;草坪外观质量总评得分41.90kg/hm2处理最高,分别高于其他3个处理1.38分、0.96分、0.47分。分析认为氮磷施用量以41.90kg/hm2为最佳。
The Poa pratensis L.was used to study the pigment content and appearance quality changes under different nitrogen and phosphorus fertilizer.The results showed that:nitrogen and phosphorus can increase the lawn chlorophyll a,b content,41.90kg/hm^2 treatment improved best and have significant difference with the control,37.71kg/hm^2 treatment was worst and with no significant difference between the control;41.90kg/hm^2 treatment can improve the carotenoid content except in August;in June and October it was significantly higher than the control;the lawn appearance quality overall score 41.90kg/hm2 treatment was highest and it was higher than other treatment 1.38 score,0.96 score,0.47 score.Analysis of nitrogen and phosphorus fertilizer to 41.90kg/hm^2 was best.
