利用32P示踪技术研究土壤磷素活性剂对大豆吸收土壤和肥料磷素量的影响
Study on effects of phosphate activator on soybean absorbing fertilizer and soil phosphate utilization ratio using 32P trace method
【摘要】 应用 3 2 P示踪技术研究了土壤磷素活化剂在磷肥肥效方面的影响。结果表明 ,施用土壤磷素活化剂可增加土壤磷素和肥料磷素的供应强度 ,促进大豆对土壤磷素和磷肥磷素的吸收。
【Abstract】 The effects of phosphate activator on phosphorus efficiency using 32 P trace technique were studied in the article. The results showed that applying phosphate activator can raise the supplying ability of soil and fertilizer phosphate improve improve the soybean sbsorbing phosphate from soil and fertilizer and also apparently increase the phosphate utilization efficiency.
