Problems solved by technology

Tobacco is a special food. In the process of tobacco production, due to the use of low-grade organic fertilizers and excessive chemical fertilizers, the control of harmful elements and harmful organisms (viruses) is not strictly controlled. The gap is enlarged, the tissue is loose, the accumulation of organic matter is reduced, the leaves are thin after baking, the color is light, lack of elasticity, and the aroma is insufficient. The content of heavy metals is too high and the quality is reduced.
The current tobacco-specific compound fertilizers are used to produce organic tobacco leaves. Because the nutrient release of this type of fertilizer is inconsistent with the nutrient accumulation (dry matter accumulation) of tobacco, there may be certain safety hazards.

Embodiment 1

[0037] (1) Pretreatment

[0038] Concentrate potassium fulvic acid, a by-product of molasses fermentation, to 50% of the mass (that is, the water content is below 50%), and adjust its pH to 5.5-6.5 with ammonium bicarbonate; Potassium, magnesium sulfate, ferrous sulfate, copper sulfate, zinc sulfate and borax are pulverized and impurity removed.

[0039] (2) Formulate the formula according to the nutrition needed in the growth period of tobacco

[0040] Calculated by mass percentage, the dosage of molasses fermentation by-product potassium fulvic acid with a concentration of 50% is 84%, urea is 6%, phosphorus ammonium is 2.7%, amino acid powder is 5%, potassium nitrate is 1.5%, and magnesium sulfate is 0.5%. , ferrous sulfate is 0.1%, copper sulfate is 0.02%, zinc sulfate is 0.1%, and borax is 0.08%.

[0041] (3) Put various raw materials into the reaction tank step by step according to the formula in (2) for chelation. Heat the 50% potassium fulvic acid solution to 90°C, t...

Embodiment 2

[0044] The first 3 steps are the same as in Example 1, step 4, cool the chelated liquid in (3) to 35°C, and then add yeast, actinomycetes, photosynthetic bacteria, nitrogen-fixing bacteria and phosphorus and potassium solubilizing bacteria. The dosage is calculated as 3-4 million pieces per gram of product, and the liquid fertilizer is packaged before leaving the factory.

Abstract

The invention discloses a fully water-soluble fulvic acid special organic fertilizer for tobacco and a preparation method of the fertilizer, and relates to the field of novel agricultural fertilizers. The preparation method comprises the following steps: adding a 50% molasses fermentation byproduct fulvic acid liquid into a reaction tank, heating to 68-90 DEG C, adding urea and stirring for 15-25 minutes; then, sequentially adding phosphamidon, amino acid powder, potassium nitrate, magnesium sulfate, ferrous sulfate, copper sulfate, zinc sulfate and borax to chelate, and stirring for 70-90 minutes at a constant temperature; spraying and drying the chelated liquid to powder and packaging and leaving factory; or after cooling the chelated liquid to 35 DEG C, adding functional bacteria, and packaging as a liquid fertilizer and leaving factory. The technical method disclosed by the invention is less in investment, simple in equipment and easy to popularize. The product makes a contribution to improving the quality of cultivated land, increasing the fertility of soil, promoting soil repair, ensuring the safety of agricultural product and producing organic tobacco.

Description

technical field [0001] The invention relates to the field of new agricultural fertilizers, in particular to a special organic fertilizer for fully water-soluble fulvic acid tobacco and a preparation method thereof. Background technique [0002] The safety of agricultural products is one of the focuses of the central government and the common people. Our country uses 7% of the world's land to feed 22% of the world's population, and agriculture has made great achievements. However, the quality problems of agricultural products emerge one after another. One of the main problems is that the land where the crops live is constantly polluted and inferior. my country consumes 35% of the world's chemical fertilizers on 7% of the world's land, and the annual consumption of pesticides is 1.3 million tons, which is the world's average mu The use of pesticides is 2.5 times that of widespread irrational tillage, over-planting, and excessive input of agricultural chemicals that seriously ov...
