Embodiment 1

[0005] Embodiment 1, get calcium hydroxide powder (slaked lime) 65%, urea 15%, humic acid (formed by high-temperature fermentation of cornmeal) 15%, cellulose (plant wood powder, i.e. sawdust powder, the powder of wood sawing) 3%, 0.5% of foaming agent (can buffer the hardness of chemical fertilizer), 1.5% of water, and its preparation method is to add 65% of calcium hydroxide powder and 15% of urea, then add 1.5% of water, 0.5% of foaming agent, 3% cellulose, 15% humic acid, stirred for half an hour, put into extruder and carry out high temperature 70°C-80°C to extrude into small cylindrical particles with 50 catties of bags.

Embodiment 2

[0006] Embodiment 2, best embodiment, get calcium hydroxide powder (slaked lime) 70%, urea 15%, humic acid (cornmeal forms by high-temperature fermentation) 10%, cellulose (plant wood powder, i.e. sawdust powder, wood sawn powder) 3%, foaming agent 0.5%, water 1.5%, its preparation method is to add calcium hydroxide powder 70% and urea 15%, then add water 1.5%, foaming agent 0.5%, cellulose 3%, humic acid 10%, stir for half an hour, put into extruder and carry out high temperature 70 ℃-80 ℃ and extrude into cylindrical small particle 50 jins of bags and get final product.

Embodiment 3

[0007] Embodiment 3, get calcium hydroxide powder (slaked lime) 75%, urea 15%, humic acid (formed by high-temperature fermentation of cornmeal) 5%, cellulose (plant wood powder, i.e. sawdust powder, the powder of wood sawing) 3%, foaming agent 0.5%, water 1.5%, its preparation method is to add calcium hydroxide powder 75% and urea 15%, then add water 1.5%, foaming agent 0.5%, cellulose 3%, humic Stir with 5% acid for half an hour, put it into an extruder and extrude at a high temperature of 70°C-80°C to form small cylindrical particles of 50 catties and pack them into bags.

Abstract

The invention relates to a calcium fertilizer formulation and a preparation method thereof. The calcium fertilizer formulation is formed by compounding and processing calcium hydroxide powder, carbamide, humic acid, cellulose, foaming agent and water. The fertilizer applied to soil can supply plant with calcium, regulate soil acidity, lighten or eliminate the damage on soil properties and plant physiology by a great many of ions of iron, aluminum, manganese, and the like in acid soil, and has special functions of resisting drought, eliminating soil poison, strengthening seedlings and resisting first injurious frost. The calcium fertilizer is suitable for different soil, can increase nutrients to improve the soil, a soil structure and physical properties. By applying the fertilizer, the grain yield can be improved by about 40 percent to 50 percent.

Description

Technical field: [0001] The invention relates to a formula of calcium fertilizer and a preparation method thereof. Background technique: [0002] At present, most of the fertilizers applied to crops are compound fertilizers. This kind of compound fertilizer has low calcium content, low absorption rate of fertilizer implanted into the soil, great environmental pollution, and can only supplement plant nutrition alone, which is easy to cause land compaction and crop shortage. Calcium will stop growing, manifested as short and small plants, premature aging, and young leaves are curled and fragile. In severe cases, the leaves are green and yellow and gradually necrotic. Symptoms such as fullness have seriously affected agricultural production. Invention content: [0003] The object of the present invention is to overcome above-mentioned shortcoming, a kind of prescription of calcium fertilizer and preparation method thereof are provided, and it has solved existing compound fer...
