AI Technical Summary
When using ethephon as a lodging resistance regulator for corn in existing technologies, it can easily lead to a decrease in the grain filling rate, a slowdown in the dry matter accumulation rate, and a decrease in the thousand-grain weight. Excessive use can also cause slow plant growth or even stop growth, thus affecting corn yield.
A combination of 1-aminocyclopropyl-1-carboxylic acid (ACC) and 5-aminolevulinic acid (5-ALA) in a mass ratio of (5~50):1 was prepared to form a growth-controlling and yield-increasing composition or agent for use in corn growth control and yield increase.
It effectively controls excessive growth of corn, improves lodging resistance and yield, significantly increases the number of grains per ear, thousand-grain weight and yield per acre, and has no negative impact on corn growth, making it environmentally friendly.
