摘要：

为明确沼液施用对水稻生产和土壤质量的影响,该研究通过连续2 a的大田试验,以纯化肥处理为对照,设置3个沼液处理组,探究沼液与化肥配施对土壤营养指标、重金属含量及水稻产量的影响。结果显示,沼液处理使土壤中有机质、总氮和有机氮含量分别提高了7.55%~73.38%、8.02%~86.10%和3.80%~86.41%,T2的提高率最大。沼液处理使土壤中Cr、Ni、Cu、Zn、As、Pb和Hg含量下降。T2处理的水稻产量最高,较纯化肥处理提高了13.2%,T3处理使水稻产量降低了18.2%,而T1处理对水稻产量的影响不显著。沼液与化肥配施能提升土壤肥力,对土壤环境质量提高起到促进作用,且能提高水稻产量。后期需进一步通过试验明确沼液与化肥的最佳用量及配施方案。

Abstract:

In order to clarify the effects of biogas slurry application on rice production and soil quality, this study conducted field experiments for 2 consecutive years. Three biogas slurry treatment groups were set up to explore the effects of biogas slurry and chemical fertilizer on soil nutrient indexes, heavy metals conent and rice yield. The results showed that the contents of organic matter, total nitrogen and organic nitrogen in the soil were increased by 7.55%-73.38%, 8.02%-86.10% and 3.80%-86.41%, respectively, and the increase rate of T2 was the largest. The biogas slurry treatment reduced the content of Cr、Ni、Cu、Zn、As、Pb and Hg in the soil. The T2 treatment had the highest rice yield, which increased by 13.2% compared with chemical fertilizer treatment, while the T3 treatment reduced the rice yield by 18.2%, while the T1 treatment had no significant effect on the rice yield. The combined application of biogas slurry and chemical fertilizer could improve soil fertility, promoted the improvement of soil environmental quality, and increased rice yield. In the later stage, it is necessary to further determine the optimal dosage and application scheme of biogas slurry and chemical fertilizer through experiments.
