摘要
为明确融地美改良土壤的效果,以青岛市保护地土壤为研究对象,设计硅肥融地美和碧护营养套餐冲施等处理的试验示范。结果表明:施用硅肥融地美可明显提高土壤团聚体数量,较对照增加10.61%~34.49%;土壤阳离子交换量较对照增加8.56%~19.69%;土壤pH值提升0.03~0.44;土壤有效硅含量最高增幅达到68.31%;土壤交换性钙含量提高25.90%;细菌、真菌、放线菌数量分别增加45.45%、101.36%、247.06%;土壤脲酶和磷酸酶活性分别增加24.66%和42.55%。因此,施用硅肥融地美可明显改善土壤理化性质,增加微生物数量及土壤酶活性,提高土壤肥力,建议在土壤改良中进一步示范推广。
In order to clarify the effect of EcoSil on soil improvement,taking the protected soil in Qingdao City as the research object,the treatment of silicon fertilizer EcoSil and ComCat nutrition package was designed for experimental demonstration.The results showed that compared with the control treatment,using silicon fertilizer EcoSil could increase the amount of soil aggregates by 10.61%-34.49%;cation exchange capacity increased by 8.56%-19.69%,soil pH value increased by 0.03-0.44,soil available silicon content increased by 68.31%,soil exchangeable calcium content increased by 25.90%;the number of bacteria,fungi and actinomycetes increased by 45.45%,101.36%and 247.06%,respectively;soil urease and phosphatase activities increased by 24.66%and 42.55%,respectively.Therefore,application of silicon fertilizer EcoSil could significantly improve soil physical and chemical properties,increase microbial number and soil enzyme activity,improve soil fertility.It is suggested that EcoSil should be further demonstrated and popularized in soil improvement.
