CALCIC FERTILIZER AND ITS PREPARATION METHOD TO PROVIDE EXTERMINATION OF HARMFUL INSECTS AS WELL AS PROMOTION OF PLANT GROWTH, AND TO PREVENT PRECIPITATION DUE TO ITS INCREASED SOLUBILITY

摘要

PURPOSE: A calcic fertilizer and preparation method thereof are provided to give extermination of harmful insects as well as promotion of plant growth, and to prevent precipitation due to its increase solubility, thereby making its use more convenient. CONSTITUTION: The calcic fertilizer is prepared by: milling (S22) calcic wastes to less than a certain size and classifying (S23) them by the size to obtain powdered calcic fertilizer; charging a cylindrical mixer with organic wastes and caustic lime, and stirring them for slaking (S30) the lime, collecting (S31) strong alkaline vapor during the slaking process, and diluting (S32) the vapor into water to obtain a liquid fertilizer; adding (S50) the powdered calcic fertilizer to the liquid fertilizer to obtain a calcic fertilizer in the form of a suspension.
