Microbial humic acid fertilizer that enhances the secretion of 3-aminoisobutyric acid by the roots of fresh corn
By using artificially synthesized microbial humic acid fertilizer to stimulate the secretion of 3-aminoisobutyric acid in the roots of fresh corn, the problem of insufficient organic acid secretion in the roots of corn in traditional corn cultivation has been solved, thereby improving soil nutrient availability and corn yield and quality.

AI Technical Summary
Technical Problem
Traditional fresh corn cultivation results in low levels of organic acids secreted by the roots, which affects soil nutrient availability and leads to a decline in yield and quality.
Method used
Artificially synthesized microbial humic acid fertilizer is used. Pleurotus species decompose corn stalks to form microbial humic acid containing active functional groups. This is applied to the roots of fresh corn to stimulate the root system to secrete 3-aminoisobutyric acid and enhance the availability of soil nutrients.
Benefits of technology
It increases the secretion of 3-aminoisobutyric acid in the roots of fresh corn, promotes root growth, enhances soil fertility, and improves corn yield and quality.

Abstract
This invention relates to a microbial humic acid fertilizer that enhances the secretion of 3-aminoisobutyric acid (3-aminobutyric acid) by the roots of sweet corn. It is prepared by the following method: corn stalk powder is placed in a liquid culture medium and autoclaved. After autoclaving, *Pleurotus* fungi are inoculated into the liquid culture medium containing corn stalks for aerobic culture. Water is added for treatment, resulting in a mixture containing microbial fungal residues. This mixture undergoes a two-stage reaction to obtain synthetic microbial humic acid, which is then dried to obtain the synthetic microbial humic acid fertilizer. The synthetic microbial humic acid fertilizer is diluted with water and applied to the roots of sweet corn seedlings. The 3-aminoisobutyric acid content secreted by the roots of sweet corn reaches 0.0026-0.0027 ng / mg. This invention increases the secretion level of 3-aminoisobutyric acid, promotes root growth in sweet corn, and increases the root length to 28-29 cm.
