Abstract:

Abstract: Through the L9 (34) orthogonal design, the relation between seed manure, density and three economic indexs that production of sweet sorghum stem and Seed and stem saccharinity was studied in linxi area . The results showed: planting density is the major factor that affected production of sweet sorghum stem and Seed and saccharinity . The optimum condition of cultivation measure is urea 8.8 Kg/mu , diamidogen 6.2 Kg/mu , kalium slfuricum 10.6 Kg/mu and 6000 plants/mu of density in linxi area.
