草种和氮肥对飞行区生态草坪抗性及土壤理化性质的影响
Effects of Grass Species and Nitrogen Fertilizers on the Resistance of Ecological Lawns in Airfield and Soil Physical and Chemical Properties
摘要
Abstract
To establish a favorable environment for airports in Northwest China,this research investi-gated fourteen common ground cover plant species under three nitrogen fertilization levels(using urea only):10 g/m2(N1),20 g/m2(N2),and 30 g/m2(N3),with a non-fertilized group as the control(CK).Soil physicochemical properties,relative water content of lawn leaves,and winter survival rate were mea-sured to evaluate effects of grass species and fertilization on soil physicochemical properties and the drought and cold resistance of the turfgrass.in airfield environment.The results showed that the optimal fertilizer application rate for soil improvement and lawn stress resistance varied significantly among species.The best effects were observed in Festuca arundinacea,Medicago sativa,Lotus corniculatus,Lespedeza bicolor,and Lavandula angustifolia under the N2 treatment;Poa pratensis and Agropyron cristatum under the N3 treatment;and the remaining species under the N1 treatment.The fuzzy membership function analy-sis demonstrated that the combination of Agropyron cristatum and the N3 fertilization level was the optimal for enhancing turfgrass stress resistance and improving soil physicochemical properties in the flying area of Zhongchuan Airport.关键词
