[0046] The preparation method of carrying surfactant is:

[0047] (1) Take 11-bromo-1-undecanol and add isopropanol to mix according to the mass ratio of 1:8, then add dropwise chlorosulfonic acid with 45% mass of 11-bromo-1-undecanol, and control the dropping time for 30 minutes. Stir and mix at 25°C for 20 minutes to obtain a mixed solution. Take the mixed solution and add 20% sodium carbonate aqueous solution with a mass fraction of 4:2, adjust the pH to 8, stir and mix for 30 minutes, and rotavap to obtain a rotovap, which is set aside;

[0048] (2) Take selenium powder and add deionized water at a mass ratio of 5:100, stir and mix at 25°C for 10 minutes, then add sodium borohydride with 90% of the mass of the selenium powder, pass in nitrogen protection, stir and mix at 25°C for 20 minutes, and stir For the mixture, take the stirred mixture and add selenium powder in a mass ratio of 100:3, heat up to 60°C and stir and mix for 20 minutes to obtain a mixture;

Embodiment 2

[0061] The preparation method of carrying surfactant is:

[0062] (1) Take 11-bromo-1-undecanol and mix it with isopropanol according to the mass ratio of 2:9, then add dropwise chlorosulfonic acid with 50% mass of 11-bromo-1-undecanol, and control the dropping time for 40 minutes. Stir and mix at 28°C for 25 minutes to obtain a mixed solution. Take the mixed solution and add 20% sodium carbonate aqueous solution with a mass fraction of 7:4, adjust the pH to 8.5, stir and mix for 40 minutes, and rotate to evaporate to obtain a rotary evaporator, which is set aside;

[0063] (2) Take selenium powder and add deionized water according to the mass ratio of 8:130, stir and mix at 28°C for 15 minutes, then add sodium borohydride with a mass of 93% of the selenium powder, pass through nitrogen protection, stir and mix at 28°C for 25 minutes, and stir For the mixture, take the stirred mixture and add selenium powder in a mass ratio of 130:7, heat up to 65°C and stir and mix for 30 min...

Abstract

The invention discloses a moisture-preserving flower nutrient soil and a preparing method thereof, and belongs to the field of flower nutrient soil. A stimulus-responsive type carrying surfactant containing selenium is obtained after 11-bromino-1-undecanol reacts with chlorosulfonic acid and a Grignard reagent (cyclopentyl bromide) is added. In the growth process of flowers, due to the respirationand photosynthesis effect, hydrogen peroxide can be generated, and the moisture-preserving performance of the soil is improved. With distarch phosphate as the raw material, water absorption and retention are conducted through water absorption swelling; by introducing a hydrophilic group, the utilization rate of a water resource is effectively increased, and sufficient water is provided for flowerplant growth; by adding polyamine, hydrogen peroxide can be generated through oxydative degradation, and the survival rate is increased; the carrying surfactant is combined with the flower growth andmetabolism process, so a good growth environment is provided. The problem that existing flower nutrient soil is poor in scouring resistant, water retention and drought resistant effect is solved.

Description

technical field [0001] The invention belongs to the field of flower nutrition soil, and in particular relates to a moisturizing flower nutrition soil and a preparation method thereof. Background technique [0002] Potted flowers have entered thousands of households, bringing relaxed and pleasant sensory enjoyment to flower lovers. But preparing nutrient soil for potted flowers is a difficult task. Most flower lovers go to the flower market to buy nutritious soil. If you can prepare a soil with sufficient nutrients, good aggregate structure, water retention, fertilizer retention, ventilation and drainage according to the different requirements of different flower varieties for the soil, you will not only enjoy The fun of the preparation process can also be used to sell for income. The nutrient soil is specially formulated to meet the growth and development of seedlings and contains a variety of mineral nutrients. It is a bed soil that is loose and ventilated, has a strong a...
