| 摘 要： | 对11250kg/ha产量水平的高产玉米施硫肥有显著的增产效果，增产幅度可达14.6%。施硫肥玉米根层数和根条数增加，根系活力提高，叶片叶绿素含量增加．硫肥还促进植株对氮、磷、钾的吸收并使籽粒灌浆速度加快。

| Abstract: | The results of experiment on application of sulphur fertilizer have shown sulphur increased remarkably the maize yield under high-yield level in 11250kg/ha.The amount of increasing in production was 14.6%.The application of sulphur fertilizercould increase the amount of roots and root-layers,the activity of root.system and the content of chlorophyll in leaves,as well as the rate of seed-filling and the absorption.of nitrogen,phosphorus and potassium in plants. |
