Description
Technical Field
The invention relates to the field of inorganic fertilizers, in particular to a calcium-containing macroelement water-soluble fertilizer and a preparation method thereof.
Background
Calcium is one of the medium elements required by plant growth, and plays a very important role in the growth and development process of plants. Not only can stabilize cell membrane and cell wall, but also can promote synthesis of carbohydrate and protein in fruit and balance of physiological activity in plant body, etc., and can prevent fruit cracking, enhance resistance to fungal diseases and promote various physiological activities in plant body. The water-soluble fertilizer is added with calcium element, theoretically, the water-soluble fertilizer has the effects of high nutrient utilization rate, low use cost and quick response.
However, in practical use, after calcium ions in the conventional fertilizer are dissolved in water, the calcium ions and phosphate ions form a water-insoluble precipitate. Mineral nutrients need to be dissolved in water and can be absorbed and utilized by crops, so that most of calcium ions are fixed in soil after being applied to the soil and cannot be absorbed and utilized. Not only reduces the effect of calcium and phosphorus, but also causes the lack of sufficient calcium element for the growth of crops, and the phenomena of reduced fruit quality, low storage resistance and the like easily appear in the later period. Therefore, the calcium element and the phosphorus element need to be combined in advance, so that the calcium element and the phosphorus element do not generate precipitate after being dissolved in water, and thus the calcium element and the phosphorus element can play a role together.
Ammonium polyphosphate is a novel fertilizer, is a polyphosphate containing nitrogen and phosphorus, and mainly comprises ammonium orthophosphate, ammonium pyrophosphate, ammonium tripolyphosphate, ammonium tetrapolyphosphate, ammonium pentapolyphosphate, ammonium polyphosphate and the like. The short-chain ammonium polyphosphate has high solubility, can dissolve more phosphorus elements in water and is absorbed and utilized by crops; after entering the soil, the phosphorus gradually hydrolyzes into orthophosphoric acid for being absorbed and utilized by crops, and is slow-release long-acting phosphorus; has chelating effect on metal ions, and can improve the absorption and utilization efficiency of other nutrients.
The zinc phosphite contains phosphite and zinc element. The phosphite can stimulate crops to generate polyphenols and plant protection matters, activate enzymes related to a defense system, have excellent control effects on common diseases such as epidemic diseases, downy mildew, root rot, late blight and the like, and are approved by wide scientific and technological workers and growers; the zinc element is a component of various enzymes in the plant body, promotes various metabolic activities, synthesizes auxin, enhances the stress resistance of the plant and the like, and has very important functions.
Therefore, the calcium ions and the phosphate ions are combined according to a specific proportion and form, and meanwhile, the polyphosphate is used for improving the solubility and the efficiency of the calcium ions and the phosphate ions and the zinc phosphite is used for improving the disease resistance of crops, so that the special compound fertilizer can play a very good effect after being applied to plants.
