| 摘 要： | 为了研究污泥农用的有效性,通过田间试验,开展了污泥农用前后土壤理化性质及作物产量变化研究.结果表明,随着污泥施用量的增加,土壤容重最大降低了14.8%;水稳性团粒总量达31.5%;速效氮、磷的含量和土壤中的有机质含量明显增多;小麦和玉米都增产,其中污泥施用量为56.25 t/hm~2时,小麦增产达极显著水平;玉米的产量都比对照要高,而且产量随施肥量的增加而增大.

| Abstract: | For studying the effectiveness of agricultural utilization of sewage sludge,soil physical and chemi-cal properties and crop output before and after sewage sludge utilization were studied by the field experiment of sludge utilization. Results showed that along with increased sludge application quantity,the maximum soil bulk density was reduced by 14.8% and the quantity of water stable aggregates amounted to 31.5%.The contents of available Nitrogen and available Phosphor were significantly increased and the content of organic matter was increased simultaneously. The output of wheat and corn increased , sludge application quantity was 56.25t/ hm2,and wheat production increase reached the extremely remarkable level. Corn output was higher than the contrast and increased with the increased quantity of fertilizer |
