Plant growth regulator composition containing brassinolide, chlorin iron and coronatine and application thereof

Abstract

The invention discloses a plant growth regulator composition containing brassinolide, chlorine iron and coronatine and application thereof. The plant growth regulator composition is prepared from the following components in parts by weight: 0.001 to 1 part of brassinolide, 0.001 to 0.1 part of chlorine iron and 0.01 to 10 parts of coronatine. According to the invention, the activation performance of various enzymes can be improved, the metabolism of plants is accelerated, and the growth of crops is promoted; crops are induced to improve the resistance to cold injury and over-low-temperature cold injury period safely; the composition has significant effects in the aspects of synergism of nutrient balance in plants, increase of yield and improvement of quality.

Description

technical field [0001] The invention relates to the technical field of agricultural growth regulators, in particular to a plant growth regulator composition containing brassinolide, iron chlorin and coronatine and its application. Background technique [0002] Temperature is one of the important ecological factors affecting plant growth and distribution. Low temperature often causes physiological disorders in thermophilic plants, metabolic disorders, injuries and even death. The impact of low temperature on plants includes chilling injury and freezing injury. Chilling injury is the damage to plants caused by low temperatures above zero; freezing injury is caused by the temperature falling below the freezing point and freezing in plants. In agricultural production in northern my country, some crops, especially heat-loving crops of tropical or subtropical origin, such as cucumbers and peppers, often suffer from chilling damage, with characteristic changes such as weak seedlin...

AI Technical Summary

Problems solved by technology

[0004] At present, when many artificially synthesized plant growth regulators are used alone, they often fail to achieve the desired effect. The disadvantages of single-dose application of plant growth regulators are: the biological activity is relatively single, the growth regulation effect is relatively low, and the dosage (or The use concentration) is relatively large, and generally can only play a role in regulating the growth of crops in a certain growth period

[0008] There is no report in the field of existing technical formulations about preparing a pesticide composition with brassinolide, iron chlorin and coronatine for anti-cold effect
