甜菜高糖丰产栽培供肥指标研讨

A Study of the Fertilizer Applying Index on Sugarbeet Highter Sugar Conent and High-yield

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.
