摘    要:试验结果表明,不同土壤类型,硼素施用效果不同.黑土区在NP基础上施硼平均增产块根11%,含糖提高0.3~0.9度,产糖量平均提高15%.在碳酸盐黑钙土区,施硼效果不明显.硼与氮、磷、钾的最佳配比为:N:P_2O_5:KaO:B=1:1.6:1:0.07.要素总用量为11.2kg/亩.土壤中有效硼的临界值为0.5ppm。试验还看出,施硼有明显提高叶绿素含量和促进生长发育作用,

关 键 词:硼素  产质量  最佳配比  临界值

Abstract:The experimental results have shown that the effect were not same in different soil type by boron applied. It increased the root yield av.11% with boron applied which should be based on N,P in black soil. The sugar content increased 0.3-0.9%, sugar yield increased 15%. The effect of boron applied was not significant in carbonate chernozem, the optimum proportion of B and N,P,K, N: P2O5:KO2:B= 1:1.6:1:0.07, the application rate of four elements were 11.2 kg/mu. The critical value of effect B was 0.5 ppm in the soil, It also shown that the chlorophyll content increased with B applied and promoting the sugarbeet growth and development.
Keywords:Boron element   Yield and quality   Optimum proportion   Critical value
