Description

Technical Field

[0001] The invention belongs to the technical field of liquid fertilizers, and in particular relates to a liquid fertilizer containing indolebutyric acid and S-inducible agent. Background Art

[0002] Indolebutyric acid (IBA for short) is an endogenous plant growth hormone that promotes cell division and cell growth, can induce the formation of adventitious roots, increase fruit setting, prevent fruit drop, change the ratio of male and female flowers, etc. Indolebutyric acid can enter the plant body through the tender epidermis of leaves and branches, and seeds, and be transported to the active part with the nutrient solution. Indolebutyric acid is mainly used as a rooting agent for cuttings, and can also be used as a fertilizer enhancer and foliar fertilizer enhancer to promote the division of roots of herbaceous and woody plants. It is a high-efficiency, low-toxic, spectrum-type, pollution-free biochemical preparation that is widely used in plant growth regulation and root promotion.

[0003] S-absorbent (ABA for short) is a monocyclic sesquiterpenoid compound. It is known to exist in most plants, except for some bacteria, archaea and phylum basidiophores. It is one of the five natural endogenous growth regulators of plants (auxins, gibberellins, cytokinins, ethylene and abscisic acid). The shedding effect of S-absorbent to form abscission layer is limited to a few plants. For most plants, the leaf fall is not directly caused by it, but by the effect of ethylene. S-absorbent can also induce and activate the expression of various stress resistance genes in plants, enhance the ability of plants to adapt to adverse growth environments, such as inducing plants to produce cold resistance, cold resistance, disease resistance and salt tolerance, thereby achieving the purpose of increasing production.

[0004] The compound use of plant growth regulators with different mechanisms of action can expand the application range of plant growth regulators, improve the effect, reduce the dosage of plant growth regulators, etc. Therefore, the study of the compound combination of indolebutyric acid and S-inducing factor is of great significance to the production of crops.
