对采自全国各地 2 0个土壤样品进行测定 .结果表明 ,树脂膜法测定的土壤磷值与碳酸氢钠法测定的土壤有效磷和植物实际吸磷量间具有极显著的相关性 ,国产树脂膜可代替进口树脂膜用于大田土壤有效磷测定
The soil samples collected from 20 soil samples were measured.The results showed that the soil phosphorus measured by the resin membrane method had a significant correlation with the soil available phosphorus and the actual phosphorus uptake measured by sodium bicarbonate method, Membrane can be used instead of imported resin membrane for soil available phosphorus determination
