How to Improve Watermelon Fruit Set Rate? Detailed Practical Measures
Measures to Improve Watermelon Fruit Set Rate
(Agricultural Wealth Network) First, choose varieties that set fruit easily. Such varieties have moderate or weak plant vigor and strong fruit-setting ability, and are not very sensitive to environmental temperature, light, and fertilizer and water, which helps improve the fruit set rate. Second, strictly control fertilizer and water before fruit set. In the early stage of plant growth, fertilizer and water should be properly controlled, especially reducing the use of nitrogen fertilizer, increasing the amount of phosphorus and potassium fertilizer, and reducing the number of irrigations. Third, use pruning and vine pressing to regulate plant growth and promote fruit set. For varieties with strong plant vigor and difficulty setting fruit, pinch off the growing tip when the main vine has 6 to 7 leaves, and use the side vines to moderate growth vigor and promote fruiting. Fourth, carry out artificial supplementary pollination and apply "Guazualing" (a fruit-setting hormone) to the fruit stalk.
