摘　　要：通过盆栽试验,以等养分量的有机无机肥做对照,研究了生物复混肥施用量对土壤有效N、P、K含量及玉米和油麦菜生长的影响。结果表明:生物复混肥的施用可以显著提高土壤有效N、P、K含量:施N量为0.1 g/kg土的生物复混肥处理可以显著提高玉米和油麦菜的N、P、K吸收量及玉米的生物量。The effects of different doses of compound biofertilizer on the content of soil available N, P, K and growth of maize and lettuce were studied by the pot experiment. The results showed that application of compound biofertilizer could obviously increase the content of soil available N, P and K. The amounts of N, P and K uptaked by maize and lettuce increased significantly by compound biofertilizer with a dose of N 0.1 g/kg soil, and the maize biomass increased significantly by compound biofertilizer with a dose of N 0.1 g/kg soil.
