| 摘 要： | 为研究不同养分含量污泥垃圾复混肥与化肥对油菜的鲜重、干重、养分利用率及土壤速效养分含量的影响,在施肥总量(N+P2O5+K2O)相等的基础上进行盆栽试验,结果表明:20%(N+P2O5+K2O=20%)的污泥垃圾复混肥处理的油菜鲜重与干重最高,油菜对氮、磷、钾养分的利用率也最高,分别为41%,9.2%,12%,同时明显提高了土壤有机质、速效氮和速效磷的含量,但土壤速效钾含量与其它复混肥和化肥处理无明显差异。

| Abstract: | A pot experiment was conducted to study the effects of SGCFs(compound fertilizers of sewage sludge and municipal garbage) and chemical fertilizers on the growth and nutrient utilization ratio of rape and the available nutrient content of soil based on the equal amount of nutrients(N P_2O_5 K_2O).The results showed that the fresh and dry weights and the N,P and K utilization ratios of rape were all the highest in 20% SGCF treatment,and the N,P and K utilization ratios were 41%,9.2% and 12%,respectively.The contents of soil organic matter,available N and P increased significantly at the same time,but the soil available K content had no significant difference with other compound fertilizers and chemical fertilizers treatments. |
