土壤磷营养是影响我国农业高产的主要限制因素,增施磷肥是一种“高投入、低产出”的途径,则解决磷营养问题以保持作物高产同时保护环境成为世界性的研究任务。本文就利用非生物方法(沸石、膨润土有机酸、木质素等)和生物方法(根际微生物、菌根、根系分泌物、磷酸酶),综述了土壤磷肥活化技术研究进展,探讨如何采用一定的措施对磷肥加以改性使之施入土壤后尽量少的被固定及增加土壤磷素的释放以提高磷素利用率,以期对生产实践提供一些理论参考和借鉴,并对今后磷肥活化研究进行了展望。
Phosphorus nutrition in soil is the main limiting factor of high agricultural productivity in our country. Adding phosphate fertilizer is a way of “high input and low output”, so it is a worldwide research task to solve the problem of phosphorus nutrition in order to maintain the high yield of crops while protecting the environment . In this paper, the non-biological methods (zeolite, bentonite organic acids, lignin, etc.) and biological methods (rhizosphere microbes, mycorrhizal, root exudates, phosphatase), reviewed the progress of soil phosphate fertilizer activation technology to explore how to use a certain Measures to phosphate fertilizer to be modified into the soil after as little as possible to be fixed and increase the release of soil phosphorus in order to improve the utilization of phosphorus in order to provide some theoretical references for the production practice and reference for the future research of phosphate activation Outlook.
