Special fully-watersoluble organic fertilizer for flue-cured tobacco

Abstract

The invention relates to a special fully-watersoluble organic fertilizer for flue-cured tobacco and belongs to the technical field of fertilizers. The special fully-watersoluble organic fertilizer is composed of, by weight, 28-32 parts of humic acid, 38-43 parts of water-soluble organic matters, 1-3 parts of organic calcium, 1.5-2.3 parts of organic magnesium, 0.8-1.2 parts of boron salt, 0.9-1.1 parts of copper salt, 0.85-1.2 parts of ferric salt, 0.7-1.1 parts of manganese salt, 0.9-1.3 parts of zinc salt, 7-10 parts of amino acid, 10-15 parts of fulvic acid and 0.9-1.3 parts of phosphorus pentoxide, wherein the boron salt, the copper salt, the ferric salt, the manganese salt and the zinc salt are all soluble in water. The special fully-watersoluble organic fertilizer is excellent in water solubility and less in impurities, water insoluble matters are smaller than or equal to 0.5%, and the fertilizer is quickly soluble in water and uniformly distributed into plant root soil along with water. Moreover, the special fully-watersoluble organic fertilizer is high in active ingredient content and small in usage amount, so that cost for packaging, storing, transporting and utilizing can be reduced.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a special fully water-soluble organic fertilizer for flue-cured tobacco. Background technique [0002] my country is an ancient agricultural country, which has always attached great importance to the accumulation, storage and application of organic fertilizers, and has accumulated rich experience. With the development of agricultural production, especially the progress of agricultural modernization, chemical fertilizers play a pivotal role in agricultural production. The combined application of organic fertilizers and chemical fertilizers has become the core content of my country's fertilizer policy. It is also an important measure to build high-yield and stable-yield farmland and an important guarantee for sustainable agricultural development. [0003] At present, most of the existing flue-cured tobacco fertilizers are traditional compound fertilizers. The disad...

Problems solved by technology

[0003] At present, most of the existing flue-cured tobacco fertilizers are traditional compound fertilizers. The disadvantages are that traditional compound fertilizers are easy to cause fertilizer loss, eutrophication of water bodies, serious damage to soil structure, and nutrient imbalance.

In addition, most of the fertilizers currently used in flue-cured tobacco planting are applied in solid form, or although they are applied in liquid form, their solubility is poor and there are more solid residues. The overall performance is slow fertilizer efficiency and relatively low fertilizer utilization rate. The space cannot be well matched with the growth law of the tobacco plant
