通过不同用量硅钙包裹尿素与普通尿素对土壤养分的对比试验，研究了硅钙包裹尿素对温室大棚西葫芦菜地土壤养分的影响。试验结果表明：相同施肥条件下，硅钙包裹尿素处理的土壤速效钾、有效硅、水溶性钙和镁、有机质含量高于普通尿素处理，且随着硅钙包裹尿素施入量的增加而提高，最高值出现在施入量为0.224 kg/m2时；硅钙包裹尿素处理的速效磷含量优于普通尿素处理，其含量随硅钙包裹尿素施入量增加而降低；硅钙包裹肥对碱解氮起到了缓释效果，在生长后期含量较高，且随施肥量增加而提高。

The effect of different amount of Si-Ca coated carbamide fertilizer and carbamide on soil fertility were stud-ied with contrast Experiment. The results showed that under the same fertilization conditions, the contents of available potassium, available silicon, water soluble calcium and magnesium, organic matter were higher in wrapped fertilizer treatment than those in the carbamide treatment. These indice increased with the enhancing of fertilizer. The maximum vaule appeared in the application of 0.224 kg/m2 coated fertilizer. The wrapped fertilizer increased with the enhancing of fertilizer that caused by slow-releasing on available nitrogen.
