Prohexadione calcium has a significant and clear effect in promoting the growth of underground rhizomes and tubers. Its core mechanism is to regulate the distribution of nutrients within the plant, directing more photosynthetic products and nutrients to the underground parts.
The specific effects of Prohexadione calcium are as follows:
* **Promoting tuber and rhizome enlargement:** Prohexadione calcium effectively inhibits excessive growth of above-ground stems and leaves, allowing a large amount of nutrients to be transferred to the underground tubers or rhizomes, thereby significantly promoting their enlargement, increasing dry matter content, and improving yield and quality.
* **Increasing yield and storage resistance:** When used on crops such as sweet potatoes, potatoes, ginger, Ophiopogon japonicus, Panax notoginseng, and yams, it can make the tubers and rhizomes larger and more uniform, while also enhancing their storage capacity and reducing storage and transportation losses.
* **Enhancing root vitality:** Prohexadione calcium can also promote root development, making the root system more developed and improving the root system's ability to absorb water and nutrients, providing a solid foundation for the enlargement of the underground parts.
In summary, Prohexadione calcium is a highly effective plant growth regulator widely used in tuber and rhizome crops. Its "controlling above-ground growth and promoting underground growth" characteristic makes it particularly effective in improving the yield and marketability of tuber and rhizome crops.
