AI Technical Summary

Technical Problem

Existing plant growth regulators are difficult to achieve the dual goals of stress resistance and survival preservation as well as stable yield and increased income in saline-alkali land. In particular, they are prone to inhibiting the yield formation of staple crops such as wheat. Traditional improvement methods are costly and time-consuming, and are difficult to achieve rapid results.

Method used

By integrating multiple substances such as active extracts of Suaeda salsa, propionyl brassinolide, crocin, and perilla lactone, a multi-pathway synergistic compound regulator is constructed to activate the antioxidant defense, osmotic regulation, photosynthetic promotion, and systemic stress resistance signaling network in crops, thereby improving wheat tolerance and yield under salt and alkali stress.

Benefits of technology

It significantly enhances the stress resistance and yield of wheat in saline-alkali land, ensures its normal physiological functions, promotes root development and photosynthesis, and realizes the sustainable development of agriculture in saline-alkali land.

Abstract

This invention discloses a stress-resistant and yield-increasing plant growth regulator, its preparation method, and its application, belonging to the field of plant growth regulators. The stress-resistant and yield-increasing plant growth regulator of this invention comprises the following raw materials: *Suaeda salsa* extract, a stress-resistant biostimulant, propionyl brassinolide, styracil, polyaspartic acid, γ-aminobutyric acid, emulsifier, penetrant, co-emulsifier, pH buffer, and deionized water; wherein the stress-resistant biostimulant is perilla lactone. This invention significantly improves the tolerance of wheat to salt-alkali stress by strengthening the antioxidant system and osmotic regulation capacity, ensuring its basic survival and normal physiological functions; and effectively reverses stress-induced growth inhibition through mechanisms such as promoting root development, enhancing photosynthesis, and driving product translocation to grains, thereby achieving a significant yield increase under adverse conditions.
