摘要:
磷是动植物生命活动离不开的重要营养元素，土壤的供磷水平是决定磷肥肥效的主要因素。在农业生产中，引人注目的是速效磷，测定方法比较成熟、应用广泛。第二次土壤普查迄今已20年，为了摸清土壤磷素的变化动态，对安康市1995～2003年耕地土壤有效磷化验资料进行了统计分析，并与第二次土壤普查结果进行了比较研究，结果表明，土壤有效磷呈上升趋势，严重缺磷土壤减少，但中高山地区土壤缺磷依然严重。分析了土壤有效磷含量的现状及其变化原因，提出了施肥对策，以期指导农业生产。
Abstract:
Phosphorus is an important nutrient for animals and plants,the phosphorus level in soil determines the effect of phosphatic fertilizer.In agricultural production,the determination of available phosphorus is widely used.It has been 20 years since the Second Soil Census,in order to know the dynamic change of soil phosphorus,the data of soil phosphorus in cultivated land in Ankang from 1995 to 2003 is analyzed and the result is compared with the Second Soil Census.The result shows that the available phosphorus is increasing,the area lacking phosphorus is declining,but the situation of high and middle hilly area is not well.The situation of soil available phosphorus and its change are analyzed and countermeasures are put forward so as to guide the agricultural production.
