Yong is currently in its early growth stage. Proper care during this period is crucial for healthy development and future fruit production. First, it's important to water the plants promptly when the soil becomes dry, as adequate moisture helps promote the formation of flower spikes. Second, proper thinning of flowers is essential. Sorghum is a self-pollinating plant with a high fruit set rate, which often leads to overbearing and reduced fruit quality. Therefore, it's necessary to remove early-developed flowers that are weak or poorly formed, as they tend to have poor nutrient supply and low fruiting potential. Additionally, on trees that produce too many flowers, a certain percentage of the flower spikes should be thinned out to ensure consistent yields in the following year. It’s generally recommended to allow about 50% of the branches to develop into flowers, maintaining stable production without overloading the tree. Otherwise, premature fruiting may occur, which can weaken the tree and affect long-term productivity. Finally, when the flower spikes reach about 5 cm in length, the top portion should be removed, leaving 2–3 side branches at the base. Weak, malformed, or unproductive flower branches should also be pruned to improve overall health and fruit quality.
In addition, regular fertilization is essential for the orchard. Fertilization should begin after the buds have started to develop. The best options are compound fertilizers or organic materials like peanut bran or manure. It's important to avoid fast-acting chemical fertilizers, as they can stimulate unwanted winter shoots, which may negatively impact flower quality. Lastly, due to high temperatures, some orchards may suffer from caterpillar damage. To prevent this, insecticides such as trichlorfon can be applied as needed to protect the crops. Taking these steps ensures that the sorghum plants remain healthy, productive, and ready for optimal fruiting in the coming seasons.
