Description

Technical field

[0001] The invention belongs to the technical field of agricultural fertilizers, and specifically relates to a chelated calcium fertilizer prepared by using shells and a preparation method and application thereof. Background technique

[0002] Plants can absorb and utilize many calcium sources, but most of these calcium sources are derived from inorganic calcium, such as calcium chloride and calcium nitrate. Sugar alcohol chelated calcium, known as the world's fifth-generation sugar alcohol chelating technology combined with acidification adsorption technology, enables the calcium contained in the product to be efficiently absorbed and utilized. Sugar alcohol chelated calcium uses sugar alcohol as a carrier to enter the phloem, so that calcium can be smoothly transported to the fruit organs of plants, and has a very good effect on preventing physiological diseases caused by calcium deficiency in plants. However, the existing sugar alcohol chelated calcium is stil...
