腐殖酸和改性木质素对土壤磷有效性影响的研究进展

Advances in the Effect of Humic Acid and Modified Lignin on Availability to Crops

如何减缓土壤中磷肥的老化、固定以及如何重新利用土壤中潜在磷素,对解决磷在农业生产中所引起的经济、环境和资源问题有很重要的意义。本文结合国内外已有成果和最新研究进展,综述了腐殖酸和改性木质素在提高磷素利用率、降低磷素环境压力等方面的应用和机理研究,针对目前的研究现状,指出了目前研究中面临的一些问题以及今后研究的热点。

How to decrease and slower fixation of phosphorous in soil,and how to recycle potential phosphorous in soil,were very important to help solving these problems which were found in agriculture,such as economy,environment,resource,and so on.This paper summed up the latest research achievements at home and abroad about humic acid and modified lignin,which were mainly focused on applied research and mechanism research of improving use efficiency of phosphorous and reducing environmental risk of phosphorus.At the same time,the existing problems and its hotspots in the future were also discussed.
