摘　　要：为了更加科学合理地利用固体有机废弃物,配合耕地质量建设,从2009年开始进行有机肥料长期定位试验。结果表明:在等量施氮水平下,有机肥料用量为7.5 t/hm^2时,可以使玉米增产28%以上,在22.5 t/hm^2施用水平下,玉米产量增加超过50%;使用有机肥料也可以增加土壤的有机质含量,在使用有机肥料5 a后,土壤有机质含量比对照增加3~4 g/kg,土壤的容重也处于一个合理水平,田间蓄水量可增加56~120 t/hm^2,明显增加土壤抗旱能力。The long-term organic fertilization experiment was conducted starting in 2009 to use organic solid wastes scientificly and rationally, and to strengthen the quality of cultivated land. The results showed that under the same application levels of nitrogen, the amount of organic fertilizer reached 7.5 t/hm^2, the yield of maize increased above 28%, when the amount reached 22.5%, and the yield increased above 50%. The soil organic matter content was increased by using organic fertilizer, which increased 3-4g/kg, compared to CK, after 5 years. Not only that, the soil bulk density became fit, increase soil water content 56-120 t/hm^2, which enhance drought resistant ability.
