Plant growth regulating composition containing chrolin iron and application thereof

Abstract

The invention provides a plant growth regulating composition containing chrolin iron and an application thereof. The plant growth regulating composition comprises a first active component chlorin ironand a second active component benzylaminopurine or forchlorfenuron, wherein the mass ratio of chlorin iron to benzylaminopurine is (0.001-0.5):(10-200), and the mass ratio of chlorin iron to forchlorfenuron is (0.001-0.5):(1-50). The preparation dosage form of the composition may include soluble powder, water dispersible granules, wettable powder or soluble liquid. The composition is used for promoting the growth of tomatoes and rice and improving the quality of tomatoes. The invention expands the application of chlorin iron in the field of plant growth regulators.

Description

technical field [0001] The invention belongs to the technical field of agricultural compositions, and relates to a plant growth regulating composition, in particular to a plant growth regulating composition containing iron chlorin. The invention also provides the application of the composition as a plant growth regulator. Background technique [0002] In the process of plant growth, trace physiologically active substances play an important role in the growth of plants, just like sunlight, temperature, water and other nutrients. These trace active substances have a special effect on regulating the growth and development of plants. Various endogenous trace active substances are often called plant hormones, such as auxin, gibberellin, cytokinin, etc., while non-endogenous external active substances are called plant growth regulators. [0003] The application of plant growth-regulating substances is one of the major advances in modern plant physiology and agricultural technolog...

AI Technical Summary

Problems solved by technology

Plant growth regulators generally have the characteristics of promoting plant growth at low concentrations and inhibiting plant growth at high concentrations. They must be used in a narrow dosage range to exert their normal effects, which leads to many limitations and inconveniences in practical applications; plant endogenous hormones have natural metabolic pathways Compared with the exogenous synthetic plant growth regulators currently used, the dosage is relatively high, the metabolic pathway is unclear, the chemical properties are stable, and there are many residues or long residual effects. With the continuous expansion of the scope of application, its residue has attracted great attention (Zhao Min et al., Safety of Plant Growth Regulators to Crops and the Environment, Journal of Environment and Health, 2007 (24) 5:370-372), my country It has been stipulated that chemically synthesized plant growth regulators shall not be used in the form of fertilizers and pesticides in any green food production and processing (People's Republic of China Agricultural Industry Standard NY-T393-2000 Green Food Pesticide Use Guidelines; NY-T394-2000 Green Food Fertilizer Use Guidelines)
