摘要
试验证明,甜菜高糖丰产栽培中,肥料综合效应以氮、磷、钾配比1:1.2:1最优;气候条件对甜菜含糖率影响明显;亩产2000公斤甜菜为基础计算的甜菜高糖丰产栽培供肥指标,基本上达到了养分补、缺相宜,实现了土壤的供需平衡。
The test showed, on cultivating sugarbeet higher sugar content and highyield, the rate N: P: K of the optimum fertilizer complex effect was 1: 1. 2 :1; the climate condition clearly effected on sugar percentage, on the bssis of 2000kg/mu sugarbeet yield, the fertilizer applying index basical1y reached soil nutrition offer and need ballante.
