补充资料:四股桥村
四股桥村系江西上饶玉山县四股桥乡所在地,东与外山、潭头两村相邻,南与十七都村相邻,西与大洋村相邻,北与山塘村相邻,全村共有面积9.5平方公里,耕地2369亩。共有15个自然村, 11个村民小组,900户3500个人口。9个党小组,72名中共党员。外出务工人员851人。
四股桥村交通极其方便,省级公路——玉花路通村而过,金沙溪、大西河交汇冲集河床,使该村土壤肥沃,极适宜种植水稻、蔬菜和花卉苗木。该村主要以种植水稻、芋头、花生等经济作物,水果以种植桔、信木柚为主,养殖业以猪、鸡、鸭、鹅为主。目前已从外县引进了一个甲鱼厂,并发现了地矿水600—1000万吨,有待开,发展前景看好。
该村独特的地理环境,交通便利,水电设施齐全,通讯发达,还有农历逢三、八是集市日,为该村的农副产品的流通提供了特定的条件,欢迎有识之士在这块热土上发展。
