建湖县庆丰乡董徐村有自然沟塘水面150亩,其中内塘30亩,河沟120亩。1978年开始发展沟塘养鱼,年亩单产只有50公斤左右,经济效益甚微。针对该地自然资源情况,我们提出了鱼——禽——蚌混养模式,即在水面养禽,水中养鱼、育蚌。实践证明,用生态学原理来指导生产,其经济效益、社会效益、生态效益比较显著。该村82年、83年运用这一理论进行小面积试验获得成功。村民陈兆83年在围养的4亩水面中养鸭70只,(养鸡150只,鸡粪供肥水),吊养珍珠蚌2600只,84年出售珍珠10公斤,总收入一万多元。从84年起至目前,全村有60%村民
Dongxu Village, Qingfeng Township, Jianhu County has 150 mu of natural ditches with 30 mu of inner ponds and 120 mu of river ditches. Ditch pond fish began to develop in 1978, only about 50 kg per mu yield, economic benefits are minimal. In response to the natural resources in the area, we proposed a fish-bird-mussel polyculture model, that is, poultry in water, fish in water, and mussel. Practice has proved that using ecological principles to guide the production of its economic, social, ecological benefits are more significant. The village 82 years, 83 years using this theory for small area test was successful. Villagers Chen trillion in 83 acres of 4 acres of water surface in raising 70 ducks, (chicken 150, chicken manure for fertilizer), hanging pearl mussel 2600, 84 years to sell pearl 10 kg, the total income of more than 10,000 yuan . From 84 till now, the village has 60% of villagers
