AI Technical Summary

Technical Problem

Existing technologies for lodging resistance in summer maize suffer from shortcomings such as insufficient targeting, poor system stability and low matching degree with application scenarios, making it difficult to achieve synergistic improvement in root system fixation, basal internode strengthening and leaf sheath area support.

Method used

The formulation and application method of water-soluble fertilizer for lodging resistance in summer maize based on biostimulants involves preparing biostimulant stock solution and structural nutrient solution, and applying them in stages to the rhizosphere crown root development zone and the stem base and lower leaf sheath area. The method uses inner and outer ring spraying and zone spraying to ensure the synergistic effect and stability of each functional component in the liquid phase system.

Benefits of technology

It improved the specificity and overall lodging resistance of summer maize, enhanced the root system's holding capacity and the mechanical support capacity of the stem base, and achieved an improvement in lodging resistance.
