摘要
在土壤-作物生产体系中,腐植酸因可挖掘产量潜力、提升肥料利用效率而被广泛研究与应用。从腐植酸调控土壤酶活、改良重金属土壤、活化土壤养分、调控植物代谢、促进根系发育、增强植物抗逆性、提升作物产量与改善品质几个方面进行了综述,并对其在马铃薯上的应用研究进行了总结,提出了腐植酸应用于马铃薯生产中亟待解决的问题,为马铃薯高产高效提供支撑。
Humic acid is widely used in soil-plant production system because it can tap the potential of yield and improve the utilization efficiency of fertilizer.Humic acid was reviewed from several aspects,such as regulating soil enzyme activity,improving heavy metal soil,activating soil nutrients,regulating plant metabolism,promoting root development,enhancing plant stress resistance,increasing crop yield and improving quality.Also the researches on potato were summarized,and the problems that need to be solved urgently in the application of humic acid in potato production were put forward to provide supports for high yield and high efficiency potato production.
