从地区的生态地理环境和农业资源特点出发 ,分析目前江苏省河网圩区农业种植结构现状及农村产业结构调整走势 ,提出稻 -草 -禽 (渔 )生态农业模式 ,以稻稳粮 ,以草养鹅或养鱼 ,以鹅、鱼增效 ,促进农、牧、渔结合 ,提高整个农业系统的物质生产力 ,增加经济效益和可持续发展的生态效益。并探讨了该模式的技术特点和可行性 ,展示了其广阔的应用前景。
In accordance with ecological environment and characters of agricultural resources,the present condition of cropping structure and the trend of adjusting industry structure in countryside of Jiangsu paddy field were analyzed,and a new eco agricultural model“rice grass poultry(fishery)”was presented.The model connected cropping with husbandry and fishery,as a result,material productivity of the whole agricultural system,economic gain and sustainable ecological gain increased.Technical characters and feasibility of the model were also discussed,which showed its wide application prospects. Key words rice;grass;poultry;fishery;eco agriculturepth, and the parameters of deep layer (between 30 cm^60 cm) root had significant difference; the rate of active area and total area of root surface of the three treatment decreased with the increase of root system vertical depth.
