| 摘 要： | 为减轻高硼(B)对小麦的毒害作用，研究了不同土壤B浓度下磷(P)素对小麦生长的影响。结果表明，增施P素能减轻小麦B毒害症状，小麦平均黄叶率由9.95%降至7.60%；促进小麦生长，B浓度为50mg/kg时，小麦根系和地上部分生物量分别增加44.9%和11.72%，30cm以下土层根系平均增加2.1%，促进了小麦对深层养分和水分的利用。

| Abstract: | In order to search out a way to reducing the boron toxicity,effects of phosphate on wheat growth in boron toxicity soil have been studied.It is found that P can reduce the boron toxic symptom of wheat,percentage of yellow leaf decreases from 9.95% to 7.60%,and promote the growth of wheat roots and shoots by 44.9% and 11.72% respectively, when boron concentration reaches to 50mg/kg. Furthermore,deep roots below 30cm soil are increased by 2.1% which promotes wheat to better use the water and nutrition in deep soil. |
