| 摘 要： | 应用由水基成膜法研制的4种有机-无机复合材料胶结包膜肥料(B2、PS、F2、F2F)进行土柱淋洗试验,研究其在不同土壤类型条件下的钾素溶出规律。结果表明:4种胶结包膜肥料在48d内钾素累积溶出率为44.02%(红壤)>34.59%(褐土)>25.92%(黑土)。同一种胶结包膜肥料在红壤、褐土和黑土中的钾素瞬时溶出率峰值出现时间一致(以B2为例);钾素溶出峰值之前,瞬时溶出率在2~13 d内为红壤>褐土>黑土,钾素峰值溶出率为10.39%(红壤)>7.09%(褐土)>5.99%(黑土),而峰值过后,三土壤间瞬时溶出率差异不显著(P>0.05)。说明包膜肥料本身释放钾素的速率受不同质地的土壤影响较小,但其淋出量受土壤影响较大。

| Abstract: | Four kinds of organic-inorganic complex materials cement and coating fertilizers prepared by a coating method using water as the solvent were carried out to study on potassium dissolved rate in different soils with columns leaching way.The results showed that potassium accumulated dissolution rate in 48d were 44.02%(red soil)> 34.59%(drab soil)> 25.92%(black soil).As for B2,the appearing peak time of potassium instant dissolution rate was same for same kind of cement and coating fertilizer in different soil... |
