RESEARCH ON HIGH YIELDING MODEL OF SUGARCANE

Research on high yielding model of spring planted sugarcane in lowland ares of the Pearl River Delta, Guangdong Province was conducted for three years. Method of balance design with five factors and five levels was used. Plots were arranged randomly. Data were analysed by computer for correlation and regression. After optimization, an optimum cultivation mode was got.Y=2 896. 97+318. 69X2-33. 06X2.4+3. 6X2.4+2. 04X2.4-0. 89X22Where, Y is sugarcane yield. X2is the nitrogen applied. X1.4is the interaction of density and potassium. X2.4is the interaction of phosphous and potassium applied. X2.4is the interaction of nitrogen and potassium applied. The application of this high-yielding model in the field Has shown significant incease in sugarcane yield.
