Abstract
Phosphorus is one of the essential macrotrophic elements in plants. It plays an important role in physiological and biological processes such as energy metabolism, nucleic acid synthesis, photosynthesis and glycolysis. Phosphate mine is also a non-renewable mineral resource, to ensure high yield crop, our country pours a large amount of phosphate fertilizer into farmland every year. Therefore, it is imperative to study the mechanism of efficient utilization of phosphorus fertilizer and the technology of reducing weight. Therefore, how to improve the utilization efficiency of phosphorus fertilizer and soil cumulative phosphorus has become a major scientific problem related to the sustainable production of crops, the realization of weight loss and efficiency and the green development of agriculture. In this paper, the research progress on the efficient utilization of phosphorus fertilizer in soil at home and abroad was reviewed. Finally, the future research directions on the efficient utilization of phosphorus fertilizer in farmland soil were prospected.
