摘　　要：为了明确新型土壤调理剂——硅钙钾镁肥对浙江省酸性水稻土的改良效果,通过连续3 a的田间小区试验,研究硅钙钾镁肥不同用量与化肥配施对水稻产量及土壤养分含量的影响。结果表明,与习惯施肥相比,施用硅钙钾镁肥水稻增产明显,以施用硅钙钾镁肥1 500 kg·hm^(-2)增产效果较好。在土壤改良方面,施用硅钙钾镁肥可以提高土壤p H值,降低土壤交换性氢和交换性铝含量,提高土壤有效硅和盐基离子含量。In order to alleviate the acidification of paddy soil in Zhejiang Province,a three-year field plots experiment was conducted to investigate the effects of silicon,calcium,potassium and magnesium fertilizer on rice yield and soil nutrient contents.The main results showed that application of silicon,calcium,potassium and magnesium fertilizer could increase rice yields,and the optimum application rate was 1500 kg·hm-2.Meanwhile,this fertilizer also could enhance soil pH value,decrease exchangeable hydrogen and exchangeable aluminum contents,increase available silicon and base cation.
