沼液在水稻生产中的资源化利用及效益综述

Benefits and Utilization of Biogas Slurry in Rice Production

沼液是一种绿色、环保、高效可溶性有机液态肥,富含氨基酸、微量元素、水解酶、腐植酸等生物活性物质,具有刺激作物生长、增强植株抗逆性、改善作物品质等作用。介绍了沼液的来源、基本性质和主要用途,综述了沼液在水稻生产上的资源化利用方式及其对水稻生长发育和产质量的影响,并讨论了沼液在水稻生产中应用产生的经济、环境和生态效益,展望了该领域未来的主要研究方向。

The biogas slurry is a kind of green,environmental and high efficient soluble organic liquid fertilizer that is rich in amino acids,trace elements,various hydrolases,humic acid and other bioactive substances,which can stimulate crop growth,enhance stress resistance and improve product quality.This paper introduced the source,basic properties of biogas slurry,and the environmental impact caused by improper disposal,summarized different high-value-utilization methods of biogas slurry as base fertilizer instead of chemical fertilizer for topdressing and foliar fertilizer as well as their effects on rice growth,development,yield and quality.At the same time,the environmental,ecological and economic benefits of biogas slurry in the process of rice production were discussed,and the main research direction in the future was prospected.
