磷肥与有机肥料配合施用问题,近年来引起了国内农化工作者的广泛注意。一些报导认为:由于有机肥料能减少过磷酸钙与土壤的接触面积,并能在分解过程中产生二氧化碳、有机酸和螯接剂,减少了磷被土壤的固定,因而将其与过磷酸钙配合施用,能提高过磷钙的肥效。但是也有不少事实证明:由于施用了有机肥料,过磷酸钙肥效显著降低。看来有机肥料对磷肥肥效的影响,还是一个比较复杂的问题,它是否和有机肥料的用量、质量、土壤性质以及使用方法等有关,有待进一步研究。
Phosphorus fertilizer and organic fertilizer with the application of the issue in recent years caused widespread attention of domestic agrochemical workers. Some reports suggest that organic fertilizers are used in conjunction with superphosphates because they reduce the contact area of superphosphate with soil and produce carbon dioxide, organic acids and chelating agents during decomposition, reducing the fixation of phosphorus by the soil Application, can improve the efficiency of phosphorus over calcium. However, there are also many facts that: due to the application of organic fertilizer, SSP significantly reduced. It seems organic fertilizer on the effectiveness of phosphate fertilizer, or a more complex issue, whether it is with the amount of organic fertilizer, quality, soil properties and the use of methods, etc., pending further study.
