Embodiment Construction

[0034] The concrete formula of liquid calcium fertilizer of the present invention is as follows (calculated by weight percentage):

[0035] Formula 1: anhydrous calcium nitrate: 90%; urea: 2%;

[0036] Calcium Lignosulfonate: 3%; Citric Acid: 1%;

[0037] Water: 2%; Amino Acids: 2%.

[0038] Formula 2: anhydrous calcium nitrate: 83%; urea: 3%;

[0039] Calcium Lignosulfonate: 5%; Citric Acid: 2%;

[0040] Water: 3%; Amino Acids: 4%.

[0041] Formula 3: anhydrous calcium nitrate: 75%; urea: 4%;

[0042] Calcium Lignosulfonate: 7%; Citric Acid: 3%;

[0043] Water: 5%; Amino Acids: 6%.

[0044] Formula 4: anhydrous calcium nitrate: 92%; urea: 2%;

Abstract

The invention relates to a liquid calcium fertilizer and a preparation method thereof. The liquid calcium fertilizer in weight percentage comprises that: 75 percent to 94 percent of calcium nitrate, 3 percent to 15 percent of carbamide and calcium lignosulphonate, 1 percent to 5 percent of citric acid, 0.5 percent to 6 percent of amino acid and 1.5 percent to 5 percent of water. When in preparing, the amino acid, the calcium lignosulphonate, the citric acid and the carbamide are dissolved in the water to form solution, then the calcium nitrate is added in the solution; the liquid calcium fertilizer of the invention is produced after being pressed, heated and stirred. The liquid calcium fertilizer of the invention comprises more than 200g / l of calcium, which far more exceeds the calcium content of an industry standard, and can meet requirements for the calcium of general plants and fruits; By adopting the product of the invention, various diseases of the plants caused by lacking of thecalcium are reduced, hardness of the fruits are enhanced, shelf life is prolonged and decayed fruits ratio caused can be reduced.

Description

technical field [0001] The invention relates to a liquid leaf fertilizer, in particular to a liquid calcium fertilizer. Background technique [0002] Calcium is mainly transported through xylem, and the speed of upward movement is largely controlled by the intensity of transpiration. When new root growth is hindered or the air humidity is too high, even plants in calcareous soils will be deficient in calcium. Calcium deficiency is more likely to occur in the above climates in ordinary soil. Calcium deficiency in plants can cause fruit cracking, sunburn in kiwifruit due to calcium deficiency, intolerance to storage, bitter pox and water core disease in apples, calcium deficiency in pears, peel spots, and poor fruit quality. Calcium deficiency in tomatoes, peppers, and watermelons leads to navel rot; calcium deficiency in cabbage, lettuce, and cabbage leads to leaf scorch; calcium deficiency in food crops causes premature senescence, less fruit, and more grains. However, the...
