Description
Technical Field
The invention relates to the technical field of agricultural compositions, in particular to a plant growth regulating composition for cucumber, a preparation method and application thereof.
Background
In the process of plant growth, trace physiological active substances play an important role in the growth of plants like nutrients such as sunlight, temperature, water and the like, and the trace physiological active substances have a special role in regulating the growth and development of the plants. Various endogenous trace active substances are often referred to as plant hormones, such as auxins, gibberellins, cytokinins, etc., while non-endogenous additional active substances are referred to as plant growth regulators.
The application of plant growth regulating substances is one of the great advances of modern plant physiology and agricultural technology, and although the plant endogenous growth regulating active substances show strong activity under extremely low concentration, the content is extremely low, the extraction and preparation are difficult, and the price is high. Therefore, growth regulating substances endogenous to non-plants have been the focus of research.
The plant endogenous hormone has natural metabolic pathway and mode, and is not easy to accumulate. Compared with the prior art, the prior exogenous synthetic plant growth regulator has higher dosage, larger concentration, unclear metabolic pathway, stable chemical property, more residues or long residual effect period. With the continuous expansion of the application range, the residue problem of the plant growth regulator arouses high attention of people, and China has stipulated that any green food production and processing process cannot use the chemically synthesized plant growth regulator in the form of fertilizer and pesticide (agricultural industry standard NY-T393-2000 green food pesticide use criterion; NY-T394-2000 green food fertilizer use criterion of China's republic of China).
The development trend in the field is to research and develop plant growth regulators which have small dosage, stable property, no toxicity, no side effect, no influence on normal metabolic pathways and modes of plants and convenient use.
The information disclosed in this background section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person skilled in the art.
