We accompanimently observed jingjiang duck sourced of National Waterfowl Germplasm Resources Pool,and analyzed the production trait,reproductive ability and egg quality of jingjiang duck in different generations.

The result showed that the performances of Jingjiang duck were not significant in different generations.

Variations and effects on water and sediment in the Jingjiang River three outlets and Dongting Lake;

Research on BP network prediction model for diversion flow of 3 diversion outlets of Jingjiang river;

Water-sediment relation between Jingjiang River and Dongting Lake and its adjustment;

Research on the Variations of the Water and Sediment for Recent 50 Years in the Jingjiang River and Dongting Lake Area;

Improvement of Flood Control over Dongting Lake & Jingjiang Stretch by Clean Water from TGP;

Study on Flood Water Level Forecasting in Jingjiang;

River channel evolution characteristics of Jingjiang reach of the Yangtze river in the late period;

The changes of the flow and sediment into Jingjiang reach after operation of the Three Gorges reservoir have been analysed,and the tendency of the development of section morphology when the scouring of Jingjiang reach has been dealt,as well as indicated that the curving and meandering river pattern of current state will be preserved.

The optimal levels of metabolizable energy(ME)and crude protein(CP)in feeds for Sheldrake from the age of 1 d to 7 wk,being divided into three periods as 0～2 wk,3～4 wk,5～7 wk,were investigated.
