STUDIES ON PLANT NUTRITION OF EFFICIENT UTILITY FOR SOIL PHOSPHORUS
高效利用土壤磷素的植物营养学研究

The important roles,resource value and properties of phosphorus in agriculture and ecological system were reviewed.Phosphorus supply potential in the soil,differences of absorption,utilization,mechanisms,genetic characteristics and some possible strategies by using various crops or genotypes to mobilize and utilize hardly soluble phosphorus of soils were discussed.It was appraised on some theoretical and practical basis to improve bioavailability of soil hardly soluble phosphorus,efficiently utilize it by plant self potential,improve its cycle,and protect the environment,the approach will promote the sustainable advances of modern agriculture and stability of ecological systems.
