摘　　要：通过盆栽试验,玉米在不同施肥处理后土壤碱解氮、有效磷、速效钾含量会随时间变化而变化。施肥30d内,处理5(混合化肥)和处理4(有机无机复合肥)养分含量极显著高于处理2、处理3(有机肥);施肥30d后,处理5的各养分含量下降较快,而处理4则有所增加;到60d时,处理4显著高于其他处理,而处理5则和其他处理差异不显著。试验结果表明:处理4(有机无机肥)供应养分前后平稳且高,有利于作物吸收更多的养分。Results obtained in pot culture experiment indicated that the content of alkaline hydrolytic nitrogen, effective phosphorus and available potassium in maize changed with the time under different fertilization treatments, nutrient content of treatment five（mixed fertilizer） and treatment four（organic-inorganic compound fertilizer） were significantly higher than treatment two and three （organic fertil- izer） within 30 days after fertilization, the nutrient content of treatment five decreased rapidly after 30 days, but treatment four increased, the nutrient content of treatment four were much higher than other treatments at sixty days, no obvious difference was found in treatment five and other treatments. The experimental results showed that the nutrient content of treatment four was steady and higher, and was benificial to nutrient absorption of crops.
