Basic Sci Dept, Armor Tech Inst,Changchun 130117, China； 3.Chin Acad of Agric Engin, Beijing 100125, China)Abstract: Much of the water and the nutrient ingredient were lost when the green corn stalk waschopped by the traditional choppers. So, a new chopper for the green corn stalk for the goose wasdesigned, in which3-dimensioncutting was used. Inthispaper, the structureandtheparametersofthe chopper for the green corn stalk were presented. The main performances of the chopper weretested. The results showed that the water loss ratio of the green corn stalk was about 3119%, thepercentage of the chopped forage in the sizes (include three di
