摘要
为优化甜菜氮磷钾施用,提高甜菜产量、含糖率、产糖量以及肥料的利用效率,开展了甜菜品种H003氮磷钾配施试验,探讨氮磷钾配施对甜菜产量、含糖率、产糖量以及养分吸收利用的影响。结果表明:氮磷钾对甜菜产量的影响作用大小不一,其增产效应:氮磷钾。无氮区的含糖率为最高,达到13.71%,各个处理之间的产糖量没有明显的差异。各处理甜菜植株中氮和钾养分含量均为鲜叶枯叶块根,甜菜植株中磷的养分含量则为鲜叶块根枯叶。每100 kg甜菜块根N、P20,、K20养分吸收量分别为2.63、0.25、1.70 kg,氮、磷、钾肥料利用率分别为91.28%、9.38%、4.08%。
In order to optimize the application of NPK in beet,to improve the yield,sugar content,sugar production and fertilizer utilization efficiency of beet,Experiments were carried out to investigate the effects of nitrogen phosphate fertilizer on yield,sugar content,sugar yield and nutrient uptake of beet.The results show that:The effect of nitrophosphine on the yield of beet varies.Its production effect:NPK.The highest sugar content was in the nitrogen free zone,At 13.71%,There was no significant difference in sugar production between treatments.The contents of nitrogen and potassium in the treated beet plants were the same Fresh leavesDead leaves-root,The nutrient content of phosphorus in beet plants is Fresh leaves root Dead leaves.The nutrient uptake of root N,P2O5 and K2O per 100 kg of sugar beet is 2.63,0.25 and 1.70 kg respectively.N,PNK Fertilizer utilization rates were 91.28%,9.38%and 4.08%,respectively.
