    摘要:

    本文研究广东珠江三角洲沙围田春植甘蔗高产栽培模式,选用5个栽培因子,5个水平,按均匀设计,小区随机排列,连续进行3年试验。对调查数据,用电子计算机进行相关与回归分析,并经寻优建立了甘蔗高产栽培最优模式。 Y=2896.97+318.69X_2-33.06X_(1.4)+3.63X_(2.4)+2.04X_(3.4)-0.89X~2_2式中:Y产量,X_2亩施氮量,X_(1.4)密度与亩施钾量交叉项,X_(2.4)亩施磷量与亩施钾量交叉项,X_(3.4)亩施氮量与亩施钾量交叉项。 高产栽培模式经大田验证,取得显著增产增收效益。

    Abstract:

    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.
