Zoysia is a widely used lawn plants, is also a clonal plants. Through detailed observations of their growth process, and found that the Zoysia growth showing strong regularity. The main stolons and secondary stolon growth characteristics with a certain similarity. The main stolons and secondary stolons, generally about three days to form a composite section, the development of a single composite section generally last 6-7 days. 30% growth in the composite section is formed in a composite section and rapid elongation, This will not only save Zoysia overall development time, but can quickly produce multiple composite section and occupied more the niche, and improve its competitiveness. , Each composite section is formed on the main stolons, root, Ta and Tb average occurrence time of the order of 3.1 days, 4.5 days and 6.1 days. Secondary creeping above order of 3.2 days, 4.2 days, 7.6 days. Zoysia plants composite section, root, Ta and Tb morphogenesis speed linear relationship, and between each other are substantially parallel. Zoysia clonal ramets developmental time is basically the same. Ta ramets on the main stolon about 6-7 days after the formation of the first composite section, after the formation of secondary stolons. Zoysia clone plants environmental conditions outside the greenhouse, growth after nearly a growing season (May 10 to October 2), with an average 189 stolons. The number of tillers excellent fit with the regression relationship of the number of days the growth curve of the exponential function. Greenhouse, outside temperature, humidity and light measurements: greenhouse internal and external environment factor differences mainly in light. Measurements through Zoysia plants to build a greenhouse, outside the study found: the performance of the overall characteristics of Zoysia greenhouse: the longer the composite section, Mycobacterium less, growing more uniform growth patterns tend to \. \Total biomass in the root, composite section leaves the distribution ratio of 1:5.45:7.35. The greenhouse outside Zoysia overall is characterized by: composite section shorter length, branching intensity, growth patterns tend to \The total biomass of the root, section the leaf distribution ratio 1:6.45:7.3. Coefficient of variation of the number of composite section, up to 35.4%, the cumulative length coefficient of variation of the number of tillers and tillers are relatively large. Greenhouse outside the main stolon the two stolons biomass differences significant greenhouse, much larger than the greenhouse. Zoysia growth behavior showed strong plasticity and foraging characteristics. Zoysia the ramets development A general is always earlier than B ramets, both biomass quite different, and gradually increased as plant growth ongoing. Number of different components on the in Zoysia two stolons biomass regression relationship between the total length of the composite section, showing the different power function, allometric growth relationship between performance.
