我社在徐州地区东海县最北部,地处淮北陇海路东段,是一个旱改水的新稻区。1966年,我县曾从南方引进绿萍做肥料,但由于我县冬季气温低(平均温度1月-1℃,2月1.1℃,最低1月-14.1℃,2月-18.3℃),绿萍冬保不过关,试了一年便告中断。1972年,我县又从南方引种绿萍,并采取各种措施,进行越冬保种试验。1974年,我社桃李大队首先试验冬保成功,在公社党委推动下,1975年放养绿萍面积由1974年的0.8亩,扩大到2,500亩;1976年一跃为25,000亩,产萍量在2,500斤以上的达2万亩。1975年在冬保的基础上,又进一步试验冬繁,也获得成功。1976年冬季全社保萍8,000平方米,1977年1月冬繁到1.2万平方米,2月底达1.8万平方米。绿萍,过去被认为不能过长江,
