在黑土和碳酸盐黑钙土,甜菜适宜的氮磷钾比例为1:1.6:1,用量18公斤/亩.N_5P_8K_5小区根产量比对照增加35.2％,含糖增加0.82度,产糖量增加42.7％;大面积应用试验结果,根产量比对照增加29.2％.含糖增加1度,产糖量增加33.0％。块根产量比对照纯收益增加21.86元/亩.
In the black soil and carbonate chernozem, the appropriate N, P and K ratio of beet was 1: 1.6: 1 and the dosage was 18 kg / mu. The root yield of N_5P_8K_5 increased by 35.2% and the sugar content increased by 0.82 degree 42.7% of the total. The results showed that the root yield increased by 29.2% compared with the control. The sugar content increased by 1 degree and the sugar yield increased by 33.0%. Root tuber yield increased 21.86 yuan / mu over the control net income.
