Research Progress on Improving Phosphate Fertilizer Utilization in Corn
Corn is a typical phosphorus sensitive crop,however,there is a hard problem that the utilization efficiency of phosphorus fertilizer applied to the soil is not high.In this paper,by summing up factors such as varieties of maize,moisture,temperature,soil physical and chemical properties,fertilizer strategy,and utilization of tillage practices and so on,it indicated that if one of these factors was regulated,then other factors would change,so that utilization efficiency of phosphate fertilizer would be affected.Hence comprehensive regulation of each factor is an effective means to improve efficiency of P-fertilizer.With the development of high-tech agriculture,available soil phosphorus and monitoring methods of phosphorus-related indicators,advanced production technology of P-fertilizer,and appropriate machines for tillage and fertilization are the three applicable steps for comprehensive regulating the high efficient utilization of soil phosphorus in corn.
