Problems solved by technology

my country is rich in humic acid resources, peat reserves rank among the top in the world, and the quality is good, but there are problems such as low content of fulvic acid in resources, difficulty in separation, and low extraction rate. If the yield of humic acid in humic acid resources is increased, It can realize the transformation from resource advantage to economic advantage

Embodiment 1

[0013] Embodiment 1: Preparation of humic acid selenium titanium complex.

[0014] The mass percentage content of each component is: instant humic acid 70%, urea phosphate (H 3 PO 4 CO (NH 2 ) 2 ) is 25%, potassium selenium phosphate (K 3 SeP 3 o 10 ﹒ wxya 2 O) is 2.5%, titanium oxysulfate (TiOSO 4 ) is 2.5%. The above instant humic acid was purchased from Lele Humic Acid Factory, Pingxiang City, Jiangxi Province.

[0015] Put the instant humic acid into the mixer, spray the titanyl sulfate solution while stirring, the reaction time is 2 hours, then spray the potassium selenium phosphate solution into it, the reaction time is 1 hour, then mix the urea phosphate powder into it, and react The time is 1 hour, and the reaction temperature is preferably controlled at 50-60° C. to avoid volatilization of N element. It is dehydrated in a vacuum kettle.

Embodiment 2

[0016] Embodiment 2: application test of Xiangfei emerald green tea tree.

[0017] Experimental site: Huaminglou Baiyun Green Food Co., Ltd., Ningxiang County, Hunan Province.

[0018] Experimental methods and results: 60 grams of humic acid selenium titanium fertilizer. Dissolving water 30-40 liters / mu. Grain Yuqian tea: Spray once on the foliage in the early stage of bud exposure; for autumn tea and late autumn tea, spray once a month before tea picking. In the spring of 2010, the tea leaves are flourishing, and the quality has been significantly improved: the tea soup is clear and green, and does not change color for a long time; the tea fragrance is elegant, and it can be brewed for a long time.

Embodiment 3

[0019] Embodiment 3: "Y Liangyou No. 2" super rice application test.

[0020] Experimental location: Kaihui Township, Changsha County, Zhuzhou City, Liling City Super Hybrid Rice Experimental Demonstration Base of National Hybrid Rice Engineering Technology Research Center.

[0021] Experimental method and results: "Qingwang brand" rice and corn selenium-enriched foliar fertilizer prepared with 60 grams of humic acid selenium and titanium compound 90 grams per mu, mixed with 30Kg of water, selected at the beginning and full earing stage of fine mist on the leaves Spray each once. Grain production increased by 5.6-10.7%. The total amount of amino acids increased, and the most obvious increase in amino acid content in rice was lysine and cysteine, with an increase of 5.5% and 5.3% respectively, followed by 4.3% of tyrosine, and the contents of other major amino acids had different degrees. Compared with the 5667mg / 100g of the control group, the amino acid content detected was ...

Abstract

The invention discloses a selenium titanium humate composite. The composite comprises, by mass, 70% of instant humic acid, 25% of urea phosphate (H3PO4CO (NH2)2), 2.5-3% of selenium potassium phosphate (K3SeP3O10.xH2O) and 2-3% of titanyl sulfate (TiOSO4). The preparation method includes placing the instant humic acid into a blender mixer and spraying the titanyl sulfate solution with stirring for 2 hours; spraying the selenium potassium phosphate solution for 1 hour; and mixing the urea phosphate powder for 1 hour at the temperature of 50-60 DEG C, and placing the mixture into a vacuum kettle for dehydration. The selenium titanium humate composite can either be used solely or be matched with other components for comprehensive usage, can strengthen photosynthesis of plant, has drought resistant and anti-water-logging capacities; and the volume increase effect is quite remarkable.

Description

technical field [0001] The invention relates to a broad-spectrum plant growth regulator and a preparation method thereof, in particular to a compound containing selenium and titanium elements and a preparation method thereof. Background technique [0002] Selenium is one of the essential trace elements for the human body and has many physiological functions. Selenium in the soil is affected by geology, landform, climate and other factors, and the distribution is uneven. It is known that more than 40 countries and regions are deficient in selenium. China is a country seriously deficient in selenium, with about 72% of the country's land area soil Selenium deficiency, there is a low selenium belt extending from northeast to southwest. Selenium deficiency in environmental soil will lead to low selenium in plants, and low selenium in food will seriously affect the health of the people, such as Keshan disease, osteoarthritis, cardiovascular disease, epidemic hemorrhagic fever and...
