[0033] Example 1

[0034] The specific preparation method of water-soluble fertilizer includes the following steps:

[0035] Dissolve 40 kilograms of titanium sulfate in 300 kilograms of water at 60°C, add 80 kilograms of gluconic acid, and stir at 60°C at 500 rpm for 1 hour to form a titanium gluconate complex. After aging for 1-3 days, slowly add 120 kilograms of ammonium hydroxide, and stir for 1 hour at 60°C and at a speed of 1000 rpm. Settling at 50°C for 48h. (Total moles of gluconic acid): The moles of Ti(IV) is 2.44. The precipitated insoluble matter was filtered out. Dilute the filtrate with water to a titanium ion concentration of 10.0g / L (the determination of titanium ion concentration can be in accordance with the industry standard NYT 2879-2015 "Determination of Cobalt and Titanium in Water-soluble Fertilizers" 5.2 Determination of Titanium Content by the method specified by plasma emission spectrometry get on).

[0048] The specific preparation method of water-soluble fertilizer includes the following steps:

[0049] Dissolve 40 kilograms of titanium oxysulfate in 300 kilograms of water at 25°C, add 120 kilograms of gluconate lactone, and stir for 1 hour at 25°C at 500 rpm to form a titanium gluconate complex. After aging for 1-3 days, slowly add 36 kilograms of potassium hydroxide, and stir for 1 hour at 25°C and at 1000 rpm. Settling at 50°C for 24h. (Total moles of glucono lactone): The moles of Ti(IV) is 3.67. The precipitated insoluble matter was filtered out. The filtrate was diluted with water to a titanium ion concentration of 10.0g / L (the mass ratio of titanyl sulfate to water was controlled between (4-30):1). Then add this filtrate to the liquid EDTA chelated zinc, manganese, iron, magnesium ammonium salt solution (the element content of which is Mn+Zn+Fe+Mg≥100g / L), add the ratio 1:2, and mix well.

[0053] The specific preparation method of water-soluble fertilizer includes the following steps:

[0054] Dissolve 40 kilograms of titanyl sulfate and titanium sulfate in 300 kilograms of water at 40°C, add 160 kilograms of gluconate lactone, and stir at 40°C at 700 rpm for 3 hours to form a titanium gluconate complex. After aging for 1-3 days, 36 kg of triethanolamine is slowly added, and stirred for 1 hour at 50°C and at 1500 rpm. Settling at 50°C for 30h. (Total moles of glucono lactone): The moles of Ti(IV) is 4.88. The precipitated insoluble matter is filtered out to remove most of the sulfate ion. When the filtrate is heated to evaporate and concentrated to a weight reduction of about 40%, it is converted to 80°C vacuum drying, when it is dried into a paste, it is taken out and cooled into a solid. Then add this solid to the mixture of solid powdery EDTA chelated zinc, manganese, iron, magnesium potassium salt and sodium octaborate (the element content ...

Abstract

The invention provides water-soluble fertilizer and a preparation method thereof. The water-soluble fertilizer is mainly composed of titanium gluconate complex and alkaline substance, wherein the titanium gluconate complex is prepared from gluconic acid substance and titanium compound according to a coordination molar ratio of (2-5):1. The preparation method includes: (A), enabling the gluconic acid substance and the titanium compound to be in coordination, and allowing reaction at 25-60 DEG C for 1-3h to obtain the titanium gluconate complex; (B), aging for 1-3d, neutralizing, settling, filtering, and adding other substances to obtain the water-soluble fertilizer. Gluconic acid is used as a ligand to coordinate with titanium ions to form titanium gluconate complex functional fertilizer. The fertilizer is nontoxic, can be better absorbed and utilized by crops, is environment-friendly, more reasonable in element proportioning, capable of improving yield and quality of the crops and freeof causing soil caking and has the advantages of being capable of managing soil and environment-friendly.

Description

technical field [0001] The invention relates to the field of fertilizer processing, in particular to a water-soluble fertilizer and a preparation method thereof. Background technique [0002] Regarding the application of element titanium in agriculture, there have been many research reports on the application of element titanium in agriculture. It has been proved that titanium-containing fertilizer is a broad-spectrum, low-use functional fertilizer, which has a good promotion effect on the physiological activities of plants, can improve the absorption of various nutrients by plants, and enhance plant resistance to disease and stress. ability, increase crop yield, and improve crop quality, so titanium-containing fertilizer is a promising new type of fertilizer. Due to the unstable properties of inorganic titanium salts, it is easy to decompose into water-insoluble titanium dioxide under natural conditions, which cannot be absorbed and utilized by plants. At present, a variet...
