磷素对自然系统和农业系统所具有的深远影响仅次于氮而远远高于其他元素。从磷的总体肥力水平上看,磷素缺乏问题是全球性问题。如果土壤全磷含量低作物就极易缺磷,但丰磷土壤容易导致大量的有效磷进入水体造成环境灾难。因此,准确的土壤磷测试方法无论是对农业增产还是对环境保护都具有十分重要的意义。在过去的近百年中,科技工作者在土壤磷素的有效性、磷素的转化、化学测试磷的方法及其作用模式方面做了大量的研究。参35。
The far-reaching impact of phosphorus on natural and agricultural systems is second only to nitrogen and much higher than other elements. From the perspective of the overall level of phosphorus fertility, the problem of phosphorus deficiency is a global issue. If the total phosphorus content of soils is extremely vulnerable to phosphorus deficiency, phosphorus-rich soil can easily lead to a large amount of available phosphorus into the water causing environmental catastrophe. Therefore, the accurate soil phosphorus test method is of great significance to both agricultural production and environmental protection. In the past century or so, scientists have done a great deal of research on the effectiveness of soil phosphorus, the conversion of phosphorus, the method of chemical testing of phosphorus, and its mode of action.
