| description | The invention relates to liquid chelated calcium as well as a preparation method and use thereof and belongs to the chemical fertilizer filed in agricultural science and farming techniques. The invention provides the liquid chelated calcium and the preparation method thereof. Active ingredients of the liquid chelated calcium disclosed by the invention are prepared by chelating 45-70 parts by weight of calcium nitrate and 10-25 parts by weight of polyhydroxy compounds in water, wherein the polyhydroxy compounds are ethylene glycol, glycerol, mannitol, xylitol, sorbitol or glucose. The liquid chelated calcium disclosed by the invention is high in calcium content which is greater than 120 g/L, safe and non-toxic, free from harmful effect on crops, can be mixed with other pesticides, weakly-acidic and neutral fertilizers for use, good in water solubility for being conveniently mixed with water for using and metering, good in stability, and can be stored by resisting a low temperature; besides, the liquid chelated |
