Description

Technical Field

[0001] The present invention relates to the technical field of flower and fruit protection agents, and specifically to a flower and fruit protection agent for jujube trees and a preparation method thereof. Background Art

[0002] The existing technologies of flower and fruit protection agents for jujube trees mainly include spraying plant growth regulators (such as plant hormones, amino acids, etc.) to improve the ability of jujube trees to retain flowers and fruits. Common components include gibberellin, abscisic acid, cytokinin, etc. These components act on the physiological processes of jujube trees, such as delaying the abscission of flower buds, promoting the normal development of fruits, and reducing the phenomenon of fruit drop, thereby increasing the yield and quality of jujube trees. When using these flower and fruit protection agents, they are usually achieved in two ways: one is to activate the self-repair mechanism of plants to enhance the stability of flowers and fruits; the other is to regulate the hormone levels in plants to improve the physiological responses of jujube trees and help jujube trees resist the influence of environmental factors (such as climate change, pests and diseases, etc.). The application of flower and fruit protection agents can effectively reduce the natural fruit drop of jujube trees, promote the continuous development of fruits, and improve economic benefits.

[0003] Although the existing technologies of flower and fruit protection agents for jujube trees have improved the yield and fruit quality to a certain extent, there are still some deficiencies. First of all, the flower and fruit protection agents have a negative impact on the growth of jujube trees. Especially after long-term use, they may cause problems such as plant drug resistance and hormone level imbalance, and even lead to the weakening of the tree body. Most of the existing flower and fruit protection agents rely on chemically synthesized components, and it is difficult to completely avoid the negative impact on the environment and ecosystem.
