| 摘 要： | 采用南方长期施尿素20 a的严重酸化的第四纪红土做土培,以石灰作土壤pH调节剂,研究不同施磷水平对不同酸性红壤下墨西哥玉米生长和土壤肥力的影响。结果表明,同一石灰施用量下,施用磷肥能增加墨西哥玉米植株高度、分蘖数和生物产量,能提高土壤速效P、水溶性Mg质量分数,两者升高的幅度与施磷量呈正相关性,且土壤pH愈高升幅愈大,但对土壤Al饱和度和pH无影响。同一磷肥用量下,施石灰能增加土壤pH、土壤速效P质量分数、植株分蘖数,降低土壤Al饱和度,但对土壤水溶性Mg质量分数变化无影响。

| Abstract: | In order to study the effect of phosphorus(P) application on growth of Zea mexicana and soil fertility in acid red soils,serious acidification quaternary red soils were used for soil culture,which had been applyed urea for twenty years in southern China,and lime was used as pH regulator in this experiment.Results showed that,under the same lime level P application increased the height,tillers and biomass of Zea mexicana,promoted the mass fraction of available P and water-soluble Mg of soils.Both increasing ... |
