Abstract:

A stable silvopastoral system of stand (6-year-old Populus deltoides cv.I-69/55) and herb(exotic species and local ones) was established in the north coastal area of Jiangsu province, by the improving technique of herb breeding, stand density controlling, spatial-temporal arranging and herb sowing. The system includes 3 vertical layers, i.e., poplar trees-poplar sprouts-herb and horizontal mixed-growth pattern of several herb species in spatial niches. It is also a high yield pattern of Lolium multiflorum+Medicago sativa(November to May)-Sorghum sudanense+poplar sprouts(June to September)-Setaria faberii or Artharxon pricnodes(July to October) in temporal niches. The system drastically increases the resource utilization coefficient of the ecosystem and sustainable development capacity of the sheltering forest of the coastal area.
