摘    要:在江苏海岸带6年生2-69杨林分下,通过外来牧草引种和土著牧草开发,结合简化培育技术,时空配置技术,林分密度调控技术和牧草载培技术等林草复合生态措施,建立了稳定的林下草场,在空间上,形成杨树-杨树萌生枝-牧草的三层垂直格局和多种牧草混播的水平格局,在时间上,形成多花黑麦草+紫花苜蓿(11-5月)-苏丹草+杨树萌生枝(6-9月)-狗尾草或茅叶荩草(7-10月)的同生产产量格局,大大提高了生态系统的资源利用海岸防护林的可持续发展能力。

关 键 词:生态技术  林草复合系统  生物量  海岸带  沿海防护林  林下草场  林下放牧试验

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.
Keywords:Ecotechnique  Silvopastoral system  Biomass
