: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 %。施用JLP肥还有提高土壤与肥料养分利用率及土壤生物活性等作用
: The experimental study on the effects of polygamy active compound fertilizer (JLP fertilizer) on the fertility and soil fertility of maize was carried out from 1996 to 1999. The results showed that the application of JLP fertilizer in the corn before jointing dry weight per plant than conventional fertilizers increased 65% ~ 653%. Plant root weight increased 10 ~ 13 times. In 1997, the application rate of JLP fertilizer in the wind disaster was 0, and the lodging rate of fertilizers was 15% ~ 20%. Application of JLP fertilizer than the application of fertilizer can mature ahead of 15 ~ 20d. One-time application of corn JLP fertilizer (100 kg / hm2) as base fertilizer no longer applied other fertilizers, 10% ~ 15% more yield than conventional fertilizers and 443% of fertilizer nutrients. Application of JLP fertilizer also has the effect of improving the nutrient utilization rate of soils and fertilizers and soil biological activity
