superphosphate

A kind of new typer mixing reacter with an injection tube and a baffled chamber for producing calcium superphosphate was introduced.

介绍了由一个喷射管和一个折流室构成的用于普钙生产的新型混合反应器。

So I bought a bag of superphosphate bone meal from a flowerer shop in town at Town God’s Temple Street and mixed it into each pot as a substitute for new earth.

从城隍庙的店里买了一包磷酸骨粉，搀和在每一盆泥里，这算代替了新泥。
