preparation example Construction

[0033] see figure 1 , the preparation method of the tobacco leaf fertilizer of one embodiment, comprises the following steps:

[0034] Step S101: Weighing and pulverizing the raw materials in parts by weight, stirring and heating to 60° C., continuing to stir, and cooling.

[0035] Step S102: adjusting the pH value to 7 to 8 with citric acid to obtain tobacco leaf fertilizer.

[0036] Weigh the raw materials according to the metering ratio, pulverize them separately, put them into the reactor in batches, and heat up to 60°C under stirring. The reactor can be preferably a high-shear reactor, which is convenient to operate and uniformly stirred.

[0037] It is preferred to program the temperature up to 60° C. at a rate of 60 revolutions per minute. At this rate of temperature increase, the rate of heat transfer among the components is reasonable.

[0038] The liquid at the beginning of the reaction is alkaline, and the pH value is adjusted to 7 to 8 with citric acid. After the...

Embodiment 1

[0049] Weigh raw materials according to the following proportions: 20 parts of potassium tripolyphosphate, 20 parts of potassium citrate, 6 parts of Sargassum fermented extract, 0.5 parts of glutathione, 0.5 parts of β-deoxyglucose, 0.1 parts of S-induced 0.5 part xylooligosaccharide, 0.2 part salicylic acid, 2 parts boric acid, 0.1 part ammonium molybdate, 0.5 part EDTA chelated zinc, 0.5 EDTA chelated magnesium, 0.3 EDTA chelated manganese, EDTA chelated copper 0.3 parts and 0.5 parts of alkyl polyglucoside, 48 parts of water.

[0050] The raw materials are pulverized separately, put into a high-shear reactor for stirring in batches, heated at a speed of 60 rpm to 60°C, continued to stir, cooled, and adjusted the pH value of the liquid to 7 to 8 with citric acid to obtain a tobacco leaf fertilizer .

Embodiment 2

[0052] Weigh the raw materials according to the following proportions: 20 parts of potassium tripolyphosphate, 15 parts of potassium citrate, 3 parts of Sargassum fermented extract, 0.5 parts of glutathione, 0.5 parts of β-deoxyglucose, 0.1 parts of S-induced 0.5 part xylooligosaccharide, 0.2 part salicylic acid, 1 part boric acid, 0.1 part ammonium molybdate, 0.5 part chelated zinc EDTA, 0.5 part chelated magnesium EDTA, 0.3 part chelated manganese EDTA, 0.3 part chelated copper EDTA 0.3 parts and 0.5 parts of alkyl polyglycosides, 31 parts of water.

[0053] The raw materials are pulverized separately, put into a high-shear reactor for stirring in batches, heated at a speed of 60 rpm to 60°C, continued to stir, cooled, and adjusted the pH value of the liquid to 7 to 8 with citric acid to obtain a tobacco leaf fertilizer .

Abstract

A tobacco foliar fertilizer and a preparation method thereof. The tobacco foliar fertilizer includes following components, by weight: 20-25 parts of potassium tripolyphosphate, 15-20 parts of potassium citrate, 3-6 parts of sargassum fermentation extract, 0.5-2 parts of glutathione, 0.5-2 parts of [beta]-deoxyglucose, 0.1-1 part of trans-abscisic acid, 0.5-1 part of xylooligosaccharide, 0.2-0.5 parts of salicylic acid, 1-3 parts of boric acid, 0.1-0.5 parts of ammonium molybdenate, 0.5-2 parts of EDTA-chelating zinc, 0.5-2 parts of EDTA-chelating magnesium, 0.3-2 parts of EDTA-chelating manganese, 0.3-1 part of EDTA-chelating copper, 0.5-1 part of alkyl polysaccharide glycoside and 31-56.2 parts of water. The tobacco foliar fertilizer is reasonable in combination and proportion, can promote growth of tobacco, can enhance the resistance capability on viruses, cold and dryness of tobacco, can increase yield, is green and environmental-friendly and can greatly improve quality of tobacco.

Description

technical field [0001] The invention relates to the field of tobacco leaf fertilizer, in particular to a tobacco leaf fertilizer and a preparation method thereof. Background technique [0002] my country is a big tobacco-growing country, and chemical fertilizers are the material guarantee for the sustainable development of tobacco and the basis for increasing tobacco production. The practice of the world's agricultural development has proved that the application of chemical fertilizers is the fastest, most effective and most important measure to increase production. Since 1980, China's chemical fertilizer application has grown at an average annual rate of 4%. At present, China has become the world's largest producer and consumer of chemical fertilizers. Although the arable land area only accounts for 7% of the world's total arable land area, China's chemical fertilizer application is close to 1 / 3 of the world's total. Soil acidification and compaction caused by the unreaso...
