A kind of special organic fertilizer of fully water-soluble fulvic acid tobacco and preparation method thereof

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...

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.
