The Comparative Research On The Qualities Of The Lawns Between Zoysia Matrerralla And Paspalum Vaginatum In Ji’an

The study has adopted two first-level indicator exterior quality which covers 4 secondary indexes such as density,tint,texture,and uniformity and ecosystem quality which includes 3 second-level indicators :green stage,coverage and weed intrusions,using Fuzzy Comprehensive Judgment Method to make comparisons of the qualities of turfs in different growth periods which were formed by two lawns :Zoysia matrella and Pasmalum vaginatum.The results as follows:1.Whether it is in spring,summer or autumn,the density of Zoysia matrella is higher than that of Paspalum vaginatum with the marked difference between them.(p<0.01)2.In spring,the tints of Zoysia matrella is obviously superior to that of Paspalum vaginatum(p<0.01);In summer and autumn,the distinction between the two lawns is not remarkable(p>0.05).3.In summer,the texture of is Paspalum vaginatum slightly worse than that of Zoysia matrella,while in spring and autumn,the texture of Paspalum vaginatum is clearly better than that of Zoysia matrella(p<0.05).4.The homogeneity of Zoysia matrella is extremely significantly higher than that of Paspalum vaginatum in spring;while in summer,the The homogeneity of Zoysia matrella is significantly higher than that of Paspalum vaginatum;while in autumn there is no remarkable differences(p>0.05).5.In the Ji’an area,the average green period of Zoysia matrella is longer than that of Paspalum vaginatum by 5.2 days with remarkable differences(p<0.01).6.In spring,the coverage of Paspalum vaginatum is extremely significantly lower than that of Zoysia matrella(p<0.01),while in summer and autumn,there is no difference between them,both up to 100%.7.Whether it is in spring,summer or autumn,the weed intrusions of Paspalum vaginatum is extremely significantly higher than that of Zoysia matrella(p<0.01).8.According to the analysis of Fuzzy Comprehensive Judgment Method in spring,summer,and autumn,the grey correlation degree of Zoysia matrella is significantly higher than that of Paspalum vaginatum,indicating that Zoysia matrella is superior to Paspalum vaginatum.
