Problems solved by technology

Since flue-cured tobacco has a relatively narrow demand for boron, boron is released slowly after being applied to the soil. Applying a large amount of boron fertilizer not only makes it difficult to achieve the purpose of efficiently supplementing boron fertilizer, but also inhibits the absorption of nitrogen and potassium, resulting in waste of fertilizer. Reduce the quality of tobacco leaves

preparation example Construction

[0025] The preparation method of the foliage fertilizer for effectively improving the boron content of flue-cured tobacco according to the present invention comprises the following steps:

[0026] (1) Prepare an aqueous solution of borax, boric acid, potassium dihydrogen phosphate, ferrous sulfate, and manganese sulfate in the formula ratio, mix and stir evenly, and form A liquid;

[0027] (2) Then dissolve the auxin, fulvic acid, and chelating agent in the formula ratio in water in turn, stir evenly and add co-solvent to fully dissolve them all to form liquid B;

[0028] (3) Mix liquid A and liquid B, stir well, add surfactant, fully dissolve;

[0029] (4) Adjust the pH value of the solution obtained in step (3) to 5.8-6.5 with an alkaline solution to obtain the product.

[0030] The variety of flue-cured tobacco is K326.

[0031] The alkali solution described in step (4) is a 1mol / L NaOH solution.

Abstract

The invention discloses a foliage fertilizer capable of effectively increasing the boron content of flue-cured tobaccos and a preparing method and an application method of the foliage fertilizer. Thefoliage fertilizer is mainly prepared from borax, boric acid, monopotassium phosphate, ferrous sulfate, manganese sulfate, fulvic acid, phytohormone, chelating agent, cosolvent, surfactant and water.By means of the foliage fertilizer capable of effectively increasing the boron content of the flue-cured tobaccos and the preparing method and the application method of the foliage fertilizer, flue-cured tobacco leaves can efficiently adsorb boric fertilizer, the absorption efficiency is improved, relevant diseases brought to the flue-cured tobacco leaves due to lack of boron are effectively avoided, and the flexibility of the tobacco leaves is improved. In the meanwhile, the foliage fertilizer contains organic components, inorganic components and microelements, and through organic combinationof the nutrients, the growth and nutritive balance of the flue-cured tobaccos can be promoted; meanwhile, the foliage fertilizer is low in cost, and has an important significance in improving the quality of the tobacco leaves and increasing the economic benefit.

Description

technical field [0001] The invention belongs to the technical field of flue-cured tobacco cultivation, and in particular relates to a foliar fertilizer for effectively increasing the boron content of flue-cured tobacco, a preparation method and an application method. Background technique [0002] Boron is an essential element for crop growth. Most of the cultivated soils in my country are deficient in boron, especially in the southern acidic soil areas. Due to the perennial humidity and rain, the amount of boron leaching in the soil is large, and the phenomenon of boron deficiency is more common. Factors affecting the availability of boron in soil mainly include texture, clay type, and interaction between elements, etc. Clay-heavy soil, high-calcium soil, or fields with a large amount of potassium fertilizer can all cause boron deficiency. [0003] Flue-cured tobacco belongs to crops that need medium boron. Boron mainly exists in the cell wall and participates in the synthe...
