| 摘 要： | 通过田间小区试验对不同磷肥用量下棉田土壤磷素与盐分含量及盐分离子相关性进行了探讨。结果表明,磷肥施用可增加全盐含量,尤其SO24-和Ca2+离子增加明显,但与对照相比,未到显著水平,大量施磷处理也不会显著增加全盐含量;不同时期不同层次中施磷量、全磷和速效磷与各种盐分离子的相关性显示,苗期和花蕾期相关性不明显,吐絮期与部分盐分离子存在显著相关性。

| Abstract: | The purpose of this research was to discuss the correlation between soil phosphorus and salt ions in cotton field through the plot experiment in the field applied with different fertilizer rate.The results showed that applying phosphate fertilizer could increase the content of total salt,especially the content of SO2-4 and Ca2+ ions.But compared with the controls,applying phosphate fertilizer could not significantly increase the content of total salt.The correlation between application rate of phosphorus,total phosphorus and available phosphorus and salt ions in seedling stage and bud stage was not significant.The correlation between boll opening stage and some salt ions was significant. |
