氮磷钾不同配比对甜菜产质量的影响

Effects of different proportion al nitrogen,phosphorous and potassium on yield and quality of sugar beet

通过内蒙古西部地区华资实业股份有限公司原料区3个不同试验点进行的甜菜氮、磷、钾不同配比试验,明确了氮素为甜菜产量和产糖量的主效因子,磷为含糖率的主效因子(达拉特旗点除外),提出了不同地区氮、磷、钾3要素的施用量及其比例。为甜菜专用肥的配方调整提供了科学依据。

The experiment s of different mixed proportions of N,P and K were carred out in the three trial areas of sugar beet planting region of Huazi Incorporated Company in the west of Inner-Mongolia,it has been proved that N was the key factor to affect root yield and sugar yield of sugar beet,P was the key factor to affect sugar content (except the area Dalate),the applied dosage and ratio of N,P and K in different region were ascertained.these experiments provided the scientific basis for redressing the ingredient of sugar beet special fertilizer.
