preparation example Construction

[0036] The present invention also provides a preparation method of a plant-derived growth regulator, comprising:

[0037]Step 1: After drying Speranthum, Artemisia annua and Veratrum respectively, crush and sieve to obtain Herb Speranthum powder, Artemisia annua powder and Veratrum herb powder; the drying temperature is preferably 60-80 °C, more preferably 70 °C, the drying time is preferably 15-24h, more preferably 20h;

[0038] Step 2: Add the Speranthema herb powder, Artemisia annua powder and Veratrum herb powder obtained in Step 1 respectively into the reaction kettle, soak in the solvent, and then perform ultrasonic extraction to obtain Speranthemus extract, Artemisia annua extract and Veratrum Grass extract; the soaking time is preferably 5-7h, more preferably 6h; the solvent is preferably ethanol, and the volume fraction of ethanol is preferably 80-90%, more preferably 85%; the ultrasonic extraction The conditions are: the extraction time is preferably 250min, the sol...

Embodiment 1

[0042] Respectively dry 25g of Speranthum japonicus, 45g of Artemisia annua and 30g of Veratrum herb at 70°C for 20 hours, pulverize them, and pass through a 250-mesh sieve to obtain herbal herb powder of Speranthum japonicus, Artemisia annua and Veratrum herb powder;

[0043] Add the above-mentioned herb powder, Artemisia annua powder and Veratrum herb powder respectively into the reaction kettle, soak in ethanol with a volume fraction of 85% for 6 hours, then perform ultrasonic extraction, and then separate and obtain the extract of Speranthemus extract and Artemisia annua extract and Veratrum extract; the extraction temperature is normal temperature, the extraction time is 250min, the solid-liquid ratio is (1:9) g / ml, and the acoustic power density is 2.5W / cm 2 , the sound wave frequency is 45 kHz;

[0044] By mixing the obtained Sperantosporum extract, Artemisia annua extract and Veratrum extract, a plant-derived growth regulator is obtained.

Embodiment 2

[0046] Respectively dry 30g of Speranthum japonicus, 50g of Artemisia annua and 35g of Veratrum herb at 90°C for 15 hours, pulverize them, and pass through a 250-mesh sieve to obtain herbal herb powder of Speranthum japonicus, Artemisia annua and Veratrum herb powder;

[0047] Add the above-mentioned herb powder, Artemisia annua powder and Veratrum herb powder respectively into the reaction kettle, soak in ethanol with a volume fraction of 90% for 7 hours, then perform ultrasonic extraction, and then separate and obtain the extract of Speranthemus extract and Artemisia annua extract product and Veratrum extract; the extraction temperature is normal temperature, the extraction time is 250min, the solid-liquid ratio is (1:10) g / ml, and the acoustic power density is 3W / cm 2 , the sound wave frequency is 50 kHz;

[0048] By mixing the obtained Sperantosporum extract, Artemisia annua extract and Veratrum extract, a plant-derived growth regulator is obtained.

Abstract

The invention provides a plant-derived growth regulating agent and a preparation method thereof, which belongs to the technical field of agriculture, and solves the problems that the existing plant-derived growth regulating agent is susceptible to the external factor, poor in effect and is generally a chemically synthesized single product. The regulating agent is prepared from the following raw materials in parts by weight: 25 to 35 parts of herba veratri nigri, 40 to 50 parts of sweet wormwood herb, and 20 to 30 parts of phryma leptostachya stem. The invention also provides a preparation method of the plant-derived growth regulating agent. The regulating agent provided by the invention sufficiently utilizes the synergistic effect of various active ingredients in the plant body, so that the yield of crops can be significantly increased, the quality can also be improved, after being used, the product is easy to degrade, no residual pollution is caused, and the environment can be protected.

Description

technical field [0001] The invention belongs to the field of agricultural technology, and in particular relates to a plant-derived growth regulator and a preparation method thereof. Background technique [0002] Plant growth regulator is the product of the comprehensive development of various science and technology such as organic synthesis, microanalysis, plant physiology and biochemistry, and modern agriculture, forestry and horticulture. In the 1920s and 1930s, it was discovered that there were traces of natural plant hormones in plants, such as ethylene, 3-indoleacetic acid, and gibberellin, which could control growth and development. In the 1940s, the research on artificially synthesized analogues began, and 2,4-D, diethyl hexanoate (DA-6), forchlorfenuron, sodium nitrophenolate, α-naphthaleneacetic acid, and Yiyadan were gradually developed. Promote the use and form a category of pesticides. For more than 30 years, more and more plant growth regulators have been arti...
