Key Watermelon Cultivation Techniques
Environmental Condition Control
The root system of watermelon develops best at 30-32°C, and the day-night temperature difference should be maintained at 8-10°C. Using high ridge cultivation can effectively prevent waterlogging, and the soil EC value should be controlled at 1.5-2.0mS/cm for the best sugar accumulation.
Water and Fertilizer Management Points
The highest water requirement is during the fruit-setting stage, and it is recommended to use a drip irrigation system. Applying potassium fertilizer during the fruit expansion stage can increase sweetness, and spraying calcium fertilizer on the leaves can prevent fruit cracking. Stop watering 7 days before harvest to ensure quality.
