Embodiment 1

[0043] A kind of plant growth regulator of the present invention, its preparation method comprises the following steps:

[0044] 1. Preparation of traditional Chinese medicine extract

[0045] 1) Weigh 100.00 g of a mixed sample of Chinese herbal medicines such as Phellodendron Phellodendron, Neem, Coptidis Rhizoma, Sophora flavescens in equal proportions, pour it into a round bottle with electric heating jacket, and then pour 1000 ml of 75% alcohol.

[0046] 2) First extraction: Turn on the electric heating mantle, extract for 25-30 minutes, and set the temperature to 90-95°C.

[0047] 3) Suction filter the extract.

[0048] 4) The second extraction: pour 500ml of 75% alcohol, extract for 25-30min, and set the temperature at 90-95°C.

[0049] 5) Suction filter the extract.

[0050] 6) Pour the filtrate into a round bottle of a rotary evaporator (no more than 1 / 3 of the total volume), and rotary evaporate to a paste under reduced pressure (rotation parameter: 60-75 / min; ref...

Abstract

The invention provides a plant growth regulator and a preparation method thereof. The plant growth regulator comprises the following raw materials in parts by mass: 90-95 parts of a traditional Chinese medicine extract; 1-2 parts of a coloring agent; 1-2 parts of a synergist; and 0.5-1 part of a stabilizer. The preparation method comprises the following steps: (1) preparing the traditional Chinese medicine extract; and (2) preparing a saturated solution by using the traditional Chinese medicine extract, adding a coloring agent, a synergist and a stabilizer according to the mass ratio of the traditional Chinese medicine extract to the coloring agent to the synergist to the stabilizer in the solution of (90-95):(1-2):(1-2):(0.5-1), and uniformly conducting mixing to obtain the plant growth regulator. According to the method, traditional Chinese medicinal materials are adopted as main components, the lily yield and quality can be effectively improved, the selected traditional Chinese medicinal materials are widely distributed, large-area cultivation and production are easy, the material source is wide, and the cost is low.

Description

technical field [0001] The invention belongs to the technical field of plant growth regulation, and in particular relates to a plant growth regulator and a preparation method thereof. Background technique [0002] Plant growth regulators are a class of substances that have similar physiological and biological effects to plant hormones. They have the function of regulating plant growth and development and are widely used in various crops. Among them, they are used in rice, wheat, soybean, It is widely used in rapeseed and other crops, and it is used in the tissue culture and seedling breeding of Chinese medicinal materials such as Codonopsis radix, Ophiopogon japonicus, Rosa japonica, ginseng, astragalus, Radix radix Radix, Radix Adenophora, Angelica, Lycium barbarum, Panax notoginseng, Platycodon grandiflorum, etc. It is widely used, but its application in field growth regulation of Chinese medicinal materials is less, especially in the application of field growth regulation...
