摘要
玉米是典型的磷敏感作物。但是施入土壤中的磷肥利用效率不高是一直难以解决的问题。通过归纳玉米品种,水分、温度,土壤理化性状,肥料运筹,以及耕作措施等各单因素对磷肥利用率的影响,指出在调控上述某一因素来提高磷肥利用效率的过程中,其他有些因素也会随之改变,从而影响磷肥利用效率。因此,从多方面入手,对各个因素进行综合调控是提高磷肥使用效率的有效手段。随着农业高新技术的发展,有效的土壤磷素以及与磷素相关指标的监测方法;先进的磷肥生产工艺;配套的耕作以及施肥器械是三个综合调控玉米高效利用土壤磷素的有效步骤。
Corn is a typical phosphorus sensitive crop, however, there is a hard problem that the utilizationefficiency of phosphorus fertilizer applied to the soil is not high. In this paper, by summing up factors such asvarieties of maize, moisture, temperature, soil physical and chemical properties, fertilizer strategy, andutilization of tillage practices and so on, it indicated that if one of these factors was regulated, then other factorswould change, so that utilization efficiency of phosphate fertilizer would be affected. Hence comprehensiveregulation of each factor is an effective means to improve efficiency of P-fertilizer. With the development ofhigh- 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 thethree applicable steps for comprehensive regulating the high efficient utilization of soil phosphorus in corn.
