摘要
在施用氮磷化肥的基础上,用硼、锌、锰肥拌种,甜菜叶的长势、块根产量、含糖率等均优于仅施同量氮、磷的处理.用微肥拌种有利于调节甜菜体内元素含量的均衡,使之接近最适比值.就提供同等块根产量而言,植株吸收的氮、磷、钾等常量元素的数量均少于仅施同量氮、磷的处理.微肥拌种有利于土壤中微量元素的有效化.
Based on NP fertilizer applied, the seed dressing with B, Zn and Mn fertilizer, the leaf vigor, root yield and sugar content are superior to NP treatment with same dosage only. It can give a balance of elements content in the plant when the seed dressing with trace fertilizer. And give to the optimum value, for getting same root yield, the absorbing capcity of NPK by sugar beet is less than the same dosage of NP treatment. The seed dressing, with trace fertilizer is advantageous to validity of trace element in soils.
