称样量对测定复混肥中水溶五氧化二磷含量的影响

The weighing samples affect on content of water-solubility P 2O 5 in compound fertilizer

肥中水溶五氧化二磷含量测得值随称样量的不同而不同，从而影响了水溶五氧化二磷占有效磷百分率。本试验证实，应尽可能地在称样量上加以控制。

The measured value of water-solubility P 2O 5 in compound fertiliger is different because of quantity of samole weighty,thereupon,the percentage of water-solubility P 2O 5 /effective P 2O 5 is affected.
