Embodiment 1

[0015] The whole herb of Polygonum cuspidatum was crushed and dried, added three times the amount of ethanol, leached for 12 hours, filtered, and the filtrate was concentrated to a certain concentration with a rotary evaporator, and then spray-dried to obtain dry powder of Polygonum cuspidatum extract. The dry powder of Polygonum cuspidatum extract was prepared into a solution with a concentration of 0.01% in water, and added preservative cinnamate, antioxidant 2,6-di-tert-butyl-4-methylphenol, synergist ammonium nitrate and sodium nitrite, pH Regulators citric acid and water, formulated as an externally stable formulation. Spray on the surface of tomato leaves that have entered the reproductive growth period. The amount of spraying is based on the water droplets dripping from the leaves, and the relevant indicators are tested after 5 days.

Embodiment 2

[0018] The whole herb of Polygonum cuspidatum was crushed and dried, added three times the amount of ethanol, leached for 12 hours, filtered, and the filtrate was concentrated to a certain concentration with a rotary evaporator, and then spray-dried to obtain dry powder of Polygonum cuspidatum extract. The dry powder of Polygonum cuspidatum extract is prepared into a solution with a concentration of 0.05% in water, and the preservative sodium benzoate, antioxidant tea polyphenol, stabilizer zinc stearate, synergist calcium phosphate and urea, pH regulator acetic acid and water are added to prepare into a stable formulation. Spray on the well-prepared seedbed soil, the amount of spraying is subject to the complete wetness of 5 cm below the surface soil, then sow the seeds into the soil, and test the relevant indicators 15 days after emergence.

Embodiment 3

[0021] The whole herb of Polygonum cuspidatum was crushed and dried, added three times the amount of ethanol, leached for 12 hours, filtered, and the filtrate was concentrated to a certain concentration with a rotary evaporator, and then spray-dried to obtain dry powder of Polygonum cuspidatum extract. The dry powder of Polygonum cuspidatum extract is prepared into a solution with a concentration of 0.1% in water, and preservative potassium sorbate, antioxidant butyl hydroxyanisole, stabilizer tribasic lead sulfate, synergist ammonium nitrate, pH regulator phosphoric acid and water are added. , formulated into a stable formulation. Spray on the well-prepared seedbed soil, the amount of spraying is subject to the complete wetness of 5 cm below the surface soil, then sow the seeds into the soil, and test the relevant indicators 15 days after emergence.

Abstract

The invention relates to a plant growth regulator extracted from a Polygonaceae plant giant knotweed and application of the plant growth regulator, and belongs to the technical field of agro-ecology. The giant knotweed multifunctional plant growth regulator is prepared by the steps of: extracting from the giant knotweed, concentrating, drying and adding a solvent. Through related experiments, thegiant knotweed used as the plant growth regulator has remarkable effects, namely a giant knotweed extract at lower concentration has an effect of promoting plant growth and a giant knotweed extract at higher concentration has a certain effect of inhibiting plant growth.

Description

technical field [0001] The invention relates to a plant growth regulator extracted from polygonum cuspidatum and its application, belonging to the field of agricultural biotechnology. Background technique [0002] Polygonum cuspidatum is derived from the roots and stems of Polygonum cuspidatum Sieb.et Zucc. It is an important traditional Chinese medicine in my country. The anthraquinones and stilbenes contained in it have a wide range of clinical curative effects. For a long time, the research on Polygonum cuspidatum has mainly focused on its pharmacological effects and clinical applications on humans, and there has been no relevant report on its research on plant growth regulation. Contents of the invention [0003] The object of the present invention is to provide a new application of Polygonum cuspidatum, and further provide a multifunctional plant growth regulator prepared from Polygonum cuspidatum. [0004] Above-mentioned technical purpose of the present invention i...
