摘要
运用"3414"肥料效应田间试验方案,研究甜菜氮、磷、钾肥配合施用效应及推荐用量。结果表明,合理配施氮、磷、钾肥,有利于提高甜菜的产量、产糖量及投入产出比,甜菜的最大产量达到80458.33 kg/hm2,比无肥区增产44.94%,最大产糖量达到12978.47 kg/hm2,比无肥区增产38.97%;根据一元二次效应方程式,获得最佳产量、最佳产糖量的N∶P2O5∶K2O分别是1∶1.4∶1和1∶1.7∶1,这与前人研究基本一致。
Based on the ＂3414＂ fertilizer experimental design,the experiment was conducted to determine the effects of N,P and K fertilizer application and recommendation for sugarbeet.The results showed that the rational ratio of N,P and K improved the sugarbeet yield,content and input-output ratio.The maximum root yield of sugarbeet was 80458.33 kg/ha and increased by 44.94%;the maximum sugar yield was 12978.47 kg/ha and increased by 38.97%,in comparison with the non-fertilizer application.By establishing the fertilizer response equation,the optimum ferterlizer ratios of root yield and sugar yield of sugarbeet were as（N∶P2O5∶K2O） 1∶1.4∶1 and 1∶1.7∶1,respectively.
