近几年，随着种植水平提高，产量的迅速递增，甜菜缺硼、缺锌现象日渐突出，缺硼、缺锌成了甜菜优质高产的限制因子。通过合理施用硼肥、锌肥，对甜菜增产增糖效果显著，酣菜一般可增产10－20％，可增糖0．3－1．4°。一、缺硼、缺锌症状1、缺硼症状甜菜是喜硼作物，甜菜缺硼表 In recent years, with the increase of planting level and the rapid increase of yield, lack of boron and zinc deficiency in beet are becoming increasingly prominent. The lack of boron and zinc deficiency have become the limiting factors for the high yield and quality of sugar beet. Through the rational use of boron and zinc fertilizer, the yield of sugar beet has obvious effect on increasing sugar production, and the yield of sugar beet generally can increase 10-20% and increase the sugar 0.3-1.4 °. First, lack of boron, zinc deficiency symptoms 1, the symptoms of boron deficiency Beet is Hi boron crops, beets lack boron table
