Problems solved by technology

[0002] According to statistics from the Food and Agriculture Organization of the United Nations (UAO), chemical fertilizers account for about 40% to 60% of the total increase in crop production. China can feed 22% of the world's population with 7% of the world's arable land. It can be said that chemical fertilizers play a decisive role. However, with the long-term, large-scale and excessive use of chemical fertilizers for more than 30 years, serious soil problems have been caused: soil acidification
Soil acidification will lead to many problems: poor soil, change soil structure, induce pests and diseases, affect the normal growth and development of plants, and more seriously, cause the loss of a large amount of mineral elements, especially calcium!
This invention adopts multiple acidic compounds to chelate calcium, and finally forms a chelated calcium fertilizer under the catalysis of the catalyst, but there are the following deficiencies: 1. The reaction process is complicated and the conditions are relatively harsh, requiring multiple catalysts and chelating agents. Control difficulty is bigger, is unfavorable for forming industrialized production, and multiple catalyst and chelating agent are expensive, unfavorable for realizing industrialized production and use, as palladium carbonate, gadolinium chloride; 2, the cost of preparing chelated calcium fertilizer with this method is high, and The flexibility of farmers' use is not enough, which is not conducive to the final promotion; 3. The processing time is long, and the production of the chelated calcium fertilizer requires tens of hours of processing time, high production costs, and large equipment loss

Abstract

The invention discloses an organic multi-calcium complex fertilizer additive and its preparation method and application. The fertilizer additive contains main components of calcium sucrose and calcium citrate, and is prepared from molasses, citric acid and calcium salt through multiple complexation reactions made. The preparation method is: dissolve citric acid in 100°C water completely, add excess calcium salt to react for 2-3 hours, then add sucrose molasses to react for 1.5-2 hours, and control the whole reaction temperature at 85°C-100°C; Precipitation, dehydration, drying, sieving, inspection and packaging to obtain the product. The calcium in the additive of the invention is easy to be absorbed and utilized by plants, is stable in plants, takes into account the characteristics of improving soil acidification environment, suppressing the occurrence of diseases and insect pests, and the like.
