【Abstract】 The study and advance of amino acidbased microelement fertilizer in lowering its cost and improving its comprehensive effects at home and abroad are reviewed, and the importance to supply microelements into soil is also expounded. The application shows that complex amino acidbased microelement fertilizer and rare earth chelate complex are of low consumption, low cost and high return. They can increase crop’s yield, improve their quality, kill fungi and insects, and decrease the residual of pesticide.更多还原
