Effects of calcium magnesium phosphate and silicon fertilizer on the growth and element uptake of pakchoi in cadmium, lead and zinc contaminated soil;

All the four kinds of modifiers lightened the poisoning effect of the heavy metals on Eulaliopsis binata,but varied in effect in the order of calcium magnesium phosphate>(CaCO_3>)organic manure>sea-foam.

Sodium salt of humic acid is selected as an adhesive to granulate fused calcium magnesium phosphate in this work.

Based on the phase diagram analysis,a new method for burden calculation of fused calcium magnesium phosphate is developed,which is simpler,faster and more practical than the methods reported before.

In this paper, the effects of humic acid-like activatnt on promoted-release and efficiency increase of ammonium phosphate and fused calcium magnesium phosphate(FCMP) were carried out by mimic test and pot experiment of com.
