在甜菜生产中,只有既增产又增糖才能使甜菜种植者和糖厂双受益。据我们几年来试验结果,多效唑对提高甜菜根产量有显效,也有许多资料表明,稀土能明显提高甜菜含糖率及根产量,国内也有许多应用增甘膦能显著提高根含糖率的报道。我们把增产、增糖剂混合施用于甜菜,试图达到既增产又增糖的目的,取得了满意效果。材料与方法 In sugar beet production, only sugar beet growers and sugar mills benefit from double production and sugar addition. According to the results of our experiments over the past few years, paclobutrazol is effective in improving the yield of beetroot. There are also many data that indicate that rare earth can significantly increase the sugar content and root yield of sugar beet. There are many domestic reports that application of glyphosate can significantly increase the root sugar content. We increase the yield, sugar agents mixed beet applied in an attempt to achieve the purpose of both increased yield and sugar, and achieved satisfactory results. Materials and Methods
