Description
Technical Field
The invention relates to the technical field of agricultural growth regulators, in particular to a compound plant growth regulator and a preparation method and application thereof.
Background
The plant growth regulator is extracted and synthesized artificially based on the structure, function and action principle of plant hormone, and can change the synthesis, transportation, metabolism and action of hormone in plant body to regulate plant growth and physiological function. The plant growth regulator can promote or inhibit the growth and development of plants at a lower concentration. Plant growth regulators have been used in crops, fruit trees and vegetables for a wide range of applications.
At present, the single use of many plant growth regulators cannot achieve the ideal effect, and the disadvantages of the single use of the plant growth regulators are as follows: the biological activity is single, the growth regulating effect is relatively low, the use amount (or use concentration) is large, and the growth regulating effect can be achieved only in a certain growth period of crops generally. When two or even more plant growth regulators are mixed, the physiological effect of the combined action is often not equal to the sum of the respective action effects, and the physiological effects are mainly expressed as three, namely synergism or additive action, antagonism action and induction action. Therefore, it is necessary to properly and rationally select and mix plant growth regulators in order to overcome or avoid the side effects, thereby achieving the desired application effects, i.e., synergism, additivity or induction, and avoiding antagonism.
Brassinolide, a novel green environment-friendly plant growth regulator, is treated by soaking seeds and spraying stems and leaves of brassinolide with proper concentration. Can promote the growth of vegetables, melons, fruits and other crops, improve the quality, increase the yield, and ensure bright color and thicker leaves. The tea leaf picking time can be advanced, and the melon and fruit can have higher sugar content, larger individual, higher yield and better storage stability. Is harmless to human and livestock, and has safe and effective dosage when used normally. The natural brassin can be widely applied to various economic crops, can increase the yield by 5-10% and can reach 30% higher, obviously improve the quality, increase the sugar content and the weight of fruits and increase the gorgeous crops. Meanwhile, the drought resistance and the cold resistance of crops can be improved, and the symptoms of plant diseases and insect pests, phytotoxicity, fertilizer damage and freezing damage of the crops can be relieved.
The dihydroporphin iron is a new-type natural plant growth regulator extracted from silkworm excrement and capable of regulating crop growth, and is mainly used for regulating crop growth and has good synergistic action for resisting adverse-rising energy and raising yield. The action mechanism is that the degradation of chlorophyll is delayed by inhibiting chlorophyllase, the chlorophyll content is increased, and the maximum photochemical efficiency (Fv/Fm) of a photosystem II (PS II) is increased; can promote the generation of NO in root cells, reduce the activity of indoleacetic acid oxidase and promote the growth of plant roots; obviously improves the activity of the active oxygen scavenging enzyme and promotes the content of proline of the antioxidant substance to rise. The results of indoor activity tests and field efficacy tests show that 0.02% of dihydroporphine iron soluble powder has good regulation activity on the growth of rape, and can increase the pod number, the grain number per pod, the thousand grain weight and the like of a single plant. The dosage concentration is 0.01-0.02 mg/kg (diluted into 10,000-20,000 times of solution of 0.02% chlorin iron soluble powder product). Spraying stem and leaf of rape in seedling stage, and spraying for 1 time before and after winter. Is safe to crops within the dosage range of the pesticide and has no phytotoxicity.
Triacontanol, can be absorbed by stem and leaf of plant, and can promote plant growth, increase accumulation of dry matter, improve permeability of cell membrane, increase chlorophyll content, increase photosynthetic strength, and enhance amylase, polyoxase, and peroxidase activity. Can promote germination, rooting, stem and leaf growth and flowering, make crops mature early, improve seed setting rate, enhance cold resistance and drought resistance, increase yield and improve product quality.
