土壤磷素形态及其有效化途径的研究进展

Research Prograss of Soil Phosphorous Types and Availablility

论述了土壤磷素分级方法、土壤不同磷素组分的转化与植物有效性的关系及影响因子等方面的研究进展,对不同分级方法的优缺点给予了评价,提出了该领域今后的重点研究方向。

In this paper,major methods for soil phosphorous fractioning,transformation of various phosphorous fractions and their availablility to crops,and some environmental factors to influence their transformation and availablility were reviewed.Suitability of those methods for soil phosphorous fractioning was evaluated,and some key aspects in the area for future study were also put forth.
