| 摘 要： | 通过番茄土壤对照试验,研究不同类型钾肥对土壤理化性质、微生物及土壤酶活性的影响,结果表明:与对照相比,施用新型含钾中微量元素肥料——"碳酶钾"能够提高番茄土壤有机质、碱解氮、速效磷、速效钾等土壤养分的含量,降低土壤酸度、土壤容重,提高土壤孔隙度,改善了土壤的理化性状;提高了土壤中细菌、真菌、放线菌等微生物的含量;同时还能够显著地增强土壤脲酶、磷酸酶、纤维素酶及过氧化氢酶的活性.

| Abstract: | To study the effect of different potassium fertilizer on soil physical and chemical properties, soil microorganism and enzyme activity, the controlled experiment of tomato soil was conducted. The results showed that compared with control, the application of ＇ Carbon Enzyme Potassium＇, a new type of potassium fertilizer containing medium trace elements, significantly improved content of soil organic matter, a- vailable nitrogen, and rapid available phosphorus and potassium, decreased soil acidity and soil bulk densi- ty. Therefore, the application of ＇Carbon Enzyme Potassium＇ improved soil physical and chemical properties. Moreover, the new type of potassium fertilizer increased the amount of bacteria, fungi and actinomycetes, and improved the content of urease, phosphatase, cellulose and catalase in soil. |
