Research on Introduction and Selection of 5 Cultivars of Lippia nodiflora

The introduction tests of 5 cultivars and native breed of Lippia nodiflora were conducted in Chongqing, and comparative studies were made of their phenological period, coverage area and biomass. The results showed that the coverage area and biomass of 5 Lippia nodiflora cultivars were significantly greater than those of the native breed. Among them, the coverage areas of No.4 and No.2 were far more than the others. No.4 had the highest proportion of underground biomass to total biomass, and followed by No.2. The two varieties of Lippia nodiflora were the ideal material for the control of rocky desertification and soil water conservation.
