Embodiment 1

[0044]Dissolve 24 kg of titanium sulfate in 300 kg of water at 60° C., add 28 kg of lactic acid, and stir for 1 hour at 60° C. with a rotational speed of 60 rpm. Then add 38 kg of tartaric acid, and stir for 1 hour at 50° C. and a rotating speed of 60 rpm. Aged at 60° C. for 2 days. (The total number of moles of lactic acid+tartaric acid): The number of moles of Ti(IV) was 5.64. Filter, and the filtrate is diluted with water to titanium ion concentration and be 1 mass % (the mensuration of titanium ion concentration can be carried out according to the method described in the following document: " graphite furnace atomic absorption spectrometry determines trace titanium in metallurgical material ", " analysis test Chamber", Vol.5, No.11, pp. 16-18, Zheng Yi, etc.), thus preparing sample 1.

[0045] Dissolve 24 kg of titanium sulfate in 300 kg of water at 60° C., add 28 kg of lactic acid, and stir for 1 hour at 60° C. with a rotational speed of 60 rpm. Aged at 60° C. for 2 da...

Embodiment 2

[0050] Add 80 grams of Vc (ascorbic acid) into 300 ml of water at 30°C and stir until dissolved. Then add 6 g of TiCl to the Vc aqueous solution 4 , and stirred for 3 hours under the condition that the rotation speed was 100rmp. Filtrate, collect the filtrate, the filtrate is a brown solution, so as to obtain the Ti-Vc complex as a comparative sample.

[0051] Sample 1 was prepared in the same manner as in Example 1. Water was added to Sample 1 and Comparative Sample respectively to dilute so that the titanium ion concentration was 0.3% by mass, and the pH was adjusted to 4 with acid. Then, the treated sample 1 and the comparative sample were sealed and stored at room temperature in a light-proof environment, and the time for precipitation to appear was observed. Sample 1 remained clear and transparent after one year. After testing, the concentration of titanium ions was almost unchanged at 0.29% by mass. A large amount of black precipitates appeared in the comparative sa...

Embodiment 3

[0054] Dissolve 24 kg of titanium sulfate in 300 kg of water at 60° C., add 28 kg of lactic acid, and stir for 1 hour at 60° C. with a rotational speed of 100 rpm. Then add 38 kg of tartaric acid, and stir for 1 hour at 50° C. and a rotating speed of 100 rpm. Aged at 60° C. for 2 days. (The total number of moles of lactic acid+tartaric acid): The number of moles of Ti(IV) was 5.64. Filtrate, dilute the filtrate with water to a titanium ion concentration of 30ppm (sample 4), 15ppm (sample 5), 10ppm (sample 6), and then carry out field experiments.

[0055] Test crop: Thai bamboo leaf spinach, its seeds were purchased from Fujian Yongan Seed Company

[0056] Soil for the test: In August 2009, it was carried out in Maoping Village, Yannan Street, Yongan City, Fujian Province. The test site was a sandy mud field with a pH value of 4.6. The main components of the soil were as follows: organic matter 16.7g / kg, alkali Nitrogen solution 109mg / kg, available phosphorus 209.2mg / kg, av...

Abstract

The invention relates to a preparation method of a titanium-complex-containing liquid fertilizer, which comprises the following steps: 1) dissolving titanyl sulfate or titanium sulfate in water; 2) adding a ligand A; 3) adding a ligand B; and 4) aging, wherein the ligand A and the ligand B are independently selected from tartaric acid, citric acid, malic acid, mandelic acid and lactic acid, and the ligand A and the ligand B are different; the ligand A, the ligand B and Ti (IV) meet the following relationship: 2 <= (the total mole number of the ligand A and the ligand B): the mole number of Ti (IV) <= 12. The invention also relates to the liquid fertilizer prepared by the method, and a solid fertilizer containing the liquid fertilizer. The titanium-complex-containing liquid fertilizer uses few ligands, has higher stability, and is still clear and transparent when being put for more than one year, and the concentration of titanium ion in a solution is almost unchanged, so the liquid fertilizer is of an excellent functional fertilizer.

Description

technical field [0001] The invention relates to the field of chemical fertilizers. Specifically, the invention relates to a liquid fertilizer containing a titanium complex, a preparation method thereof, and a solid fertilizer containing the liquid fertilizer. Background technique [0002] There have been many research reports on the application of elemental titanium in agriculture. It has been proved that titanium-containing fertilizer is a broad-spectrum, low-consumption functional fertilizer, which can promote some physiological activities of plants, improve the absorption rate of nutrients by plants, and enhance the ability of plants to resist diseases and disasters , significantly increase the yield of crops and improve the quality of crops, so it is a new type of fertilizer that has attracted much attention in recent years and needs to be promoted. [0003] Although the content of titanium in the soil is not low, almost all of it exists in the form of oxides and insolu...
