Study on Plantation of Grass Outer Fringe on Sandy Coast Shelter-forest in Guangdong Province

Establishing grass belt outer fringe on sandy coast shelter-forest is an effective method because nursery stocks were propagated by cuttings or vegetative offsprings in nutritive pot, and then transplanted at outer fringe on sandy coast shelter-forest. When the transplanted stocks have recovered their growth and formed root system. The transplanting success can be attained. Vitex rotundifolia, Launaea sarmentosa and Wedelia prostrata are very suitabe to be estabblished for the grass belt outer fringe on sandy coast shelter-forest. They are characterized by quick growth, easy striking of adventitious root and forming ramets. For a year after transplahtation, the coverage can reach 100%, 53% and 43% respectively, and the RGR on basis of present biomass is 0.653, 0.535 and 0.357 g/g.month, therefor the period from March to April is the best season for transplantation in South China.
