Seedless watermelon Wang Changzhen prevention?

The most effective way to manage the growth of watermelons is by applying a specialized plant growth regulator. Specifically, spraying "Flower Wangwang No. 3" before the emergence of the longevity phase helps redirect the plant's energy from vegetative growth to reproductive development. This practice inhibits excessive main shoot growth, promotes the formation of flower buds, and ensures better fruit set. During the flowering stage and the early fruit expansion period, applying "Zhuang Gu Ti Ling" can help thicken the stem, enhance nutrient transport, and accelerate melon development. This leads to well-shaped, juicy, and flavorful watermelons, with no issues like dropping, cracking, or deformation. Additionally, using "Fruit and Vegetable Health Care Transparent Clothing" diluted at 800 times can create a protective liquid film on the fruit surface. This coating does not interfere with the fruit’s respiration, prevents rust, reduces splitting, improves coloration and brightness, and lowers residual pesticide levels, ultimately enhancing fruit quality. By following these practices, farmers can ensure healthier, more productive watermelon crops with improved yield and quality. These techniques are supported by agricultural research and have been widely used in modern farming to optimize results.
