水氮耦合对甘草生理特性、根系生长及有效成分积累的影响
Effects of Water-Nitrogen Coupling on the Physiological Characteristics,Root Growth and Effective Components Accumulation of Glycyrrhiza uralensis
摘要
Abstract
Objective:To explore the effects of water-nitrogen coupling on photosynthesis,stress resistance,root growth,yield and effective components contents of Glycyrrhiza uralensis.Methods:A two-factor split zone pot experiment was conducted with Glycyrrhiza uralensis seedlings.The main zones were treated with different amounts of water(normal water W0,mild water W1,heavy water W2,the field water capacity was 70%,75%,80%,respectively);The secondary zones were different nitrogen application rates(no nitrogen fertil-izer N0,moderate nitrogen fertilizer application rate N1:50 g/m2,and high nitrogen fertilizer application rate N2:100 g/m2).Results:Appropriate water and nitrogen fertilizer application rates could significantly improve the photosynthetic gas exchange parameters,antiox-idant enzyme activity,osmoregulatory substance content,root growth and development,and yield and quality of Glycyrrhiza uralensis.Conclusion:W1N2 treatment can be the best treatment for improving the growth,development,yield and quality of Glycyrrhiza uralensis.When the field water capacity is 73%and the nitrogen fertilizer usage is 48～53 g/m2,it can effectively improve the yield and quality of Glycyrrhiza uralensis while saving fertilizer costs,providing a certain theoretical basis for the high-yield and efficient cultivation of Gly-cyrrhiza uralensis.关键词
