| 摘 要： | 在黄淮海平原盐渍土低产区对冬小麦喷施硼、锌、铁肥的试验结果表明,硼锌铁肥的浓度配比与冬小麦的籽实产量呈显著复相关关系。在适宜的浓度配比范围内喷施硼锌铁混合肥,可促使冬小麦根系生长。植株地上部叶面积、叶绿素含量及净光合率得到提高,作物根系对土壤中氮磷养分的吸收和利用得到改善,对产量构成因素有明显的促进作用。

| Abstract: | The experimental results indicated that a highly distinct multiple correlation occrred among the ratio of iron-boron-zinc and yield of grains in winter wheat on Saline Soil of Huang-huai-hai Plain.Within the limit of suitable concentration ratio,spraying of the mixed fertilizer of Fe-B-Zn could increase the rooting ability,leaf area.chlorophyll,net pho- tosynthesis rate and improve the uptake and utilizalion of N.P and subsequently promoted the component parts of the wheat yield. |
