猪粪尿全量还田对水稻种植化肥减量增效的影响

Effect of Pig Manure and Urine Returning to the Field on Fertilizer Reduction and Efficiency Improvement in Rice Planting

通过大田试验,研究猪粪尿全量还田对水稻产量、品质及土壤养分的影响,以期为农业废弃物资源化利用及化肥减量增效提供依据。结果表明:与常规施肥对照相比,猪粪尿还田处理水稻产量显著增加;各处理米质差异不大;土壤有机质指标与产量成正相关。因此,猪粪尿全量还田是水稻种植化肥减量增效的有效措施和途径,可推广应用。

The effect of pig manure and urine returning on rice yield,quality and soil nutrients were studied through field experiment,so as to provide basis for the utilization of agricultural waste resources and fertilizer reduction and efficiency improvement.The results showed that the yield of rice treated by pig manure urine returning to the field increased significantly compared with the conventional fertilization control;the difference of rice quality between the treatments was not significant;the soil organic matter index was positively correlated with the yield.Therefore,the total amount of pig manure urine returned to the field is an effective measure and way to reduce the application and increase the efficiency of fertilizer in rice planting,and can be widely used.
