When corn enters the jointing stage, it is the most vigorous growth period in its life, with both vegetative growth and reproductive growth going hand in hand. It is also a critical period for field management to achieve high yields, and it must be highly valued. Here are some field management skills for corn in the middle and late stages, hoping to help you grow high-yield corn.

Paclobutrazol is a highly effective plant growth regulator that can inhibit the synthesis of endogenous gibberellins in plants, thereby delaying plant growth. If wheat grows vigorously because of early sowing, Paclobutrazol is a good choice. It can effectively control the plant height of wheat, shorten the stem nodes of wheat, and thicken the stem walls. For example, for situations such as excessive tillering and slender leaves of wheat seedlings caused by early sowing, the use of Paclobutrazol can inhibit the production of ineffective tillers and make the wheat seedlings stronger. Its lasting effect is relatively long, and generally one use can control the growth momentum of wheat for a long time.

Commonly used plant growth regulators for cotton include Ethephon, Thidiazuron (TDZ), Gibberellic Acid (GA3), Sodium 1-Naphthyl Acetic Acid, Mepiquat chloride, and Uniconazole. These regulators play different roles in different stages of cotton growth.

In sugarcane fields planted for many years, the internodes of sugarcane are prone to shortening, quality decline, and yield reduction. This phenomenon is sometimes difficult to reverse even with the application of more chemical nitrogen fertilizers. The use of plant growth regulators can solve the above problems, not only significantly increase yield, but also greatly improve quality.
