A Study on the "Pond Fir-Fish-Duck"Eco-agroforest Model

An new eco-agro-forest model,in which pond fir trees(Taxodium ascendens)are planted,among the pond fir trees different fishes and duchs raised according to their water tolerant ability,has been established in Zhangduhu State Farm in Xinzhou County,Hubei province.It is found that the mean income per area of this pattern was over three times higher than that of fish pond with no trees and that of pond fir trees with no fish after eight years continuous operation,meanwhile lots of birds were attracted to this region to live. The local environment were improved and costs of controlling diseases and harmful insects were also been reduced.This pattern has a broad extending prospects in regions with water net-works in sub-tropic and warm temperature zones.
