| 摘 要： | 以黑龙江垦区牡丹江管理局八五五农场0-20cm表层土壤有效磷为研究对象,将历史数据与现有数据进行了对比,获取各类土壤磷素的变化状况。结果发现：这几个农场磷素水平在前期肥料使用中的利用率较高,而后期利用率降低,导致磷素在土壤中富集,增加了土壤有效磷的含量。在此基础上,通过项目农场近几年＂3414＂试验数据进行了分析,确定了农场土壤磷素对各作物的丰缺指标体系。指标体系的建立对于科学合理的施肥具有指导性的作用,为农场科学合理地施肥提供决策。 |

| Abstract: | Available phosphorus in 0-20 cm surface soil is studied in 855 State farm of Heilongjiang Reclamation Mudanjiang Branch Bureau,and historical data was compared with present data for various types of soil phosphorus conditions.The result of the change shows that farms phosphorus fertilizer use efficiency in the early is higher but is lower in late stage,leading to phosphorus accumulation in the soil,and increase the soil phosphorus content.Based on the project,the '3414' data in recent years were analyzed to... |
