摘　　要：:1996～ 1999年进行了聚隆活性有机复合肥 (JLP肥 )对玉米生育状况及土壤肥力影响的试验研究。结果表明 :施用JLP肥的处理在玉米拔节前单株干重比施用常规化肥增加 6 3 5 %～ 6 5 3 %。单株根重增加1 0～ 1 3倍。 1997年风灾施用JLP肥倒伏率为 0 ,施用化肥的倒伏率达 15 %～ 2 0 %。施用JLP肥比施用化肥可提前成熟 15～ 2 0d。玉米一次性施用JLP肥 (10 0 0kg/hm2 )做底肥不再施其他肥料 ,比施用常规化肥增产 10 %～ 15 % ,节省化肥养分 44 3 %。Field experiments were conducted from 1996 to 1999 to study the influence of JL active organic complex fertilizer (JLP) on the growth and development of maize, cv Upgrade 159, and soil fertility The results showed that before node elongation, the application of JLP increased plant dry weight by 63 5%～65 3% and plant root weight by 1～1 3 folds compared with that of the conventional fertilizer In 1997 when wind damage occurred, lodging rate was 0 for JLP treatment compared with 15%～20% for treatment of conventional fertilizer Plants with JLP treatment matured 15～20 d earlier than that with treatment of conventional fertilizer The single application of JLP as a base fertilizer (1000 kg/hm 2) increased yield by 10%～15% compared with that of conventional fertilizer; meanwhile, the amount of fertilizer was also reduced by 44 3% in JLP treatment The application of JLP could also increase soil fertility, efficiency of nutrient utilization and bioactivity of the soil
