| 摘 要： | 研究了硫包膜尿素对土壤性质和玉米生长的影响。结果表明,在玉米生长期内,硫包膜尿素可以显著增加土壤有效硫含量。与普通尿素相比,硫包膜尿素能够显著增加土壤水溶性SO42-含量,但在玉米成熟期不会显著酸化土壤。施用硫包膜尿素比普通尿素能够显著增加玉米叶绿素含量、株高和产量,但是硫膜对促进玉米叶绿素和株高增长作用有限,持续供氮是玉米叶绿素和株高增长的主要原因。在高、低量施肥水平下,硫包膜尿素处理比普通尿素处理2008年分别增产10.19%和15.23%,2009年分别增产10.94%和41.34%。低量施氮时硫膜能显著增产,而高量施氮时氮素的控释作用是显著增产的主要原因。

| Abstract: | Experiment was conducted to study the effects of sulfur coated urea(SCU)on soil properties and growth of maize.The results indicated that,in growth stage of maize,SCU was able to increase active SO42-of soil significantly.Compared with common urea,SCU was able to increase water-solution SO42-significantly,but it did not cause acidification of soil significantly in maturity stage of maize.In addition,SCU was able to increase chlorophyll,height and grain yield of maize significantly.But sulfur-coating was lim... |
