Rare earth sprayed watermelon increased yield and sweetened
According to the experiment, watermelons treated with rare earth elements showed significant improvements. The fruit setting rate increased by 17% to 30%, yield rose by 15% to 30%, and sugar content improved by 23%. Additionally, the ripening period was advanced by 3 to 7 days. These results highlight the positive impact of rare earth application on watermelon growth and quality.
1. **Spray Timing and Frequency**
There are three key periods for applying rare earth to watermelons: the early vine extension stage, the initial flowering phase, and the young fruit expansion period. During the first two stages, the primary goal is to boost fruit setting and increase overall yield. In the third stage, the focus shifts to enhancing fruit sweetness and sugar content. It's recommended to spray the plants 2 to 3 times during these critical growth phases to maximize benefits.
2. **Concentration and Dosage**
During the early vine spreading stage, apply 25 ml of rare earth plant treasure diluted in 30 kg of water, or use a 0.03% rare earth nitrate solution at 30 kg per acre. At the initial flowering stage, use 50 ml of the product in 40–50 kg of water, or a 0.05% nitrate solution. For the young fruit expansion period, apply 75 ml of rare earth plant treasure mixed with 50–60 kg of water, or a 0.08% nitrate solution. The rare earth plant treasure is a third-generation product that improves the absorption efficiency of rare earth elements, offering better overall results compared to traditional nitrate solutions.
3. **Application Technique**
It's best to spray on cloudy days or in the late afternoon when sunlight is less intense to avoid leaf burn. Spraying before dusk is ideal. Ensure even coverage, paying special attention to both sides of the leaves. If rain occurs within 24 hours after spraying, reapply once the rain has stopped to maintain effectiveness.
By following these guidelines, farmers can effectively utilize rare earth elements to improve the productivity and quality of their watermelon crops. This method not only enhances yield and flavor but also contributes to more efficient resource use and sustainable farming practices.
