Application of metal derivative containing chlorophyll and hydrolyzate thereof as plant growth regulator

Abstract

The invention provides an application of a metal derivative containing chlorophyll and hydrolyzate thereof as a plant growth regulator. The metal derivative containing chlorophyll and hydrolyzate thereof is selected from chlorophyll metal chelate, a chlorophyllin metal chelate and a monomeric metal chelate obtained by separating a chlorophyllin mixture. The chlorophyll is a green pigment extracted from a natural plant raw material and provided with a phaeophytin mother ring structure. The chlorophyllin is a mixture of multiple dihydroporphin components obtained by hydrolyzing the chlorophyll. The monomeric chlorophyllin component is selected from dihydroporphin-e4, dihydroporphin-e6 or phaeophorbide a monomethyl ester. Metal ions comprise bivalent or trivalent transition metal manganese, iron, copper or zinc ions in an oxidation state. The plant growth regulator provided by the invention has the advantages of safety, non-toxicity, low residue, strong activity, good effect, stable product property, controllable and reliable quality and easiness in promotion and application; the chlorophyll content of the plant can be increased, the root growth is promoted, the germination ratio is increased, the stress resistance is enhanced and the yield is also increased.

Description

technical field [0001] The invention relates to a new use of a substance, in particular to the application of a metal derivative containing chlorophyll and its hydrolyzate as a novel plant growth regulator. Background technique [0002] Chlorophyll is the main pigment for photosynthesis of plants, widely exists in the chloroplasts of higher plants, and is the material basis of photosynthesis. In terms of chemical structure, chlorophyll is a kind of compound that chelates metal magnesium. Plant leaves contain about 0.25% of total chlorophyll, which mainly consists of chlorophyll a, chlorophyll b, chlorophyll c, chlorophyll d and other isomers, which are naturally extracted. The chlorophyll is a mixture of these isomers (monomers), which have in common the pheophytin parent ring (phorbin) structure; chlorophyll is rich in chemical reactivity and forms chelates with transition metals It is an important reaction of chlorophyll, which can obtain a class of products with applicat...

Problems solved by technology

Plant growth regulators generally have the characteristics of promoting plant growth at low concentrations and inhibiting plant growth at high concentrations. They must be used in a narrow dosage range to exert their normal effects, which leads to many limitations and inconveniences in practical applications; plant endogenous hormones have natural metabolic pathways Compared with the exogenous synthetic plant growth regulators currently used, the dosage is relatively high, the metabolic pathway is unclear, the chemical properties are stable, and there are many residues or long residual effects. With the continuous expansion of the scope of application, its residue has attracted great attention (Zhao Min et al., Safety of plant growth regulators to crops and the environment, Journal of Environment and Health, 2007 (24) 5: 370-372), my country It has been stipulated that chemically synthesized plant growth regulators shall not be used in the form of fertilizers and pesticides in any green food production and processing (People's Republic of China Agricultural Industry Standard NY-T 393-2000 Guidelines for the Use of Green Food Pesticides; NY-T 394-2000 Green Food Fertilizer Usage Guidelines)
