Technical Field
The invention belongs to the field of fertilizers, and particularly relates to an ion retention agent, an anti-cracking water-soluble fertilizer and a preparation method thereof.
Background
The citrus fruit cracking is caused by unbalanced growth between peel and pulp tissues, is a reaction of fruits to the uncoordinated internal and external growth of the fruits under the adverse condition, is a physiological disease problem commonly existing in the production of citrus, mainly occurs in the expanding growth period of the fruits, and generally has the fruit cracking rate of 10-20 percent and is up to 20-30 percent in severe cases. The fruit cracking can directly affect the yield and the quality of the oranges, and huge economic losses are caused to the production of the oranges. Calcium is an essential nutrient element for plants and plays an important role in the growth and development stages of the plants, for example, the calcium can form calcium pectate with acid to stabilize the structure of cell walls; calcium can link phospholipid molecules, and has the function of stabilizing cell membranes; most of intracellular calcium exists in vacuole, and the balance of anions and cations in vacuole has important contribution and osmotic regulation effect. Research shows that the high and low calcium content in the fruit determines the structural firmness of fruit cells and the stability of a membrane system and is closely related to the occurrence of fruit cracking. Nowadays, measures such as spraying of calcium fertilizer, reasonable shaping and trimming, yield control and the like are adopted for reducing the incidence rate of fruit cracking of crops, but the effect of reducing the fruit cracking rate due to higher technical level, difficult yield control and the like in actual production by other measures such as shaping and trimming, yield control and the like is not ideal; spraying the calcium fertilizer is relatively simple and easy to master, but the fertilizer application period, the fertilizer components and the proportion are strictly controlled to be effective. At present, many enterprises develop various calcium-containing fertilizers to reduce the fruit cracking rate, for example, patent publications CN111763117A, CN111480650a and CN110922252A, etc., which mix calcium with other components and spray the calcium on the foliage of plants, but these calcium-containing fertilizers have low inorganic nutrients and even do not contain major elements required by plants such as NPK, etc., and these fertilizers are mostly liquid fertilizers, and have high storage and transportation costs, and the salt content in the fertilizers is higher than that of solid fertilizers, and are easy to damage water fertilizer application equipment.
