【摘要】 连续6季定位试验证明,施用污泥复合肥对水稻生产、稻米品质均无不良影响。各项生产指标和产量的考查及米质分析表明,施用污泥复合肥略好于同品种等数量的化肥,但差异未达显著水平,稻米和土壤中的重金属元素含量与施用化肥的也无明显差异,未曾超出各国对农业土壤中重金属元素的建议允许浓度。说明污水处理后的污泥制作复合肥在本试验条件水稻生产上应用是安全而有效的。更多还原

【Abstract】 Results of a long term experiment or 6 consecutive crops of paddy rice proved that applying sludge compounded fertilizer (SCF) to rice had not any negative impacts on rice growth or grain quality.Compared with those using chemical fertilizer (CF),nutrient content of which equaled to SCF,application of SCF seemed to be better than that of CF,but there was not significant difference between SCF and CF,according to data from examination of production target or analysis of grain quality.There was no significant difference either on heavy metal element content in rice grain and soil,the concentration of heavy metal element did not exceed the allowance generally suggested by various countries in the world It is shown,therefore,that application of fertilizer compounded with sludge from sewage treatment on rice production is safe and effective.更多还原
