The main reason why pumpkins bloom but do not sit on melons is due to lack of sunlight or excessive nitrogen fertilizer. It may also be due to insufficient pollination of pumpkins and many other factors, resulting in more pumpkins and less flowers.
Ways to make pumpkins sit more melons:
Method One: Pick the top of the pumpkin in a timely manner: When the pumpkin vine grows to 2 meters, the main vine growth point is removed, so that the main vine grows 3 to 4 branch vines, and blooms and melons.
Method 2: Put a scaffold on the pumpkin: When the pumpkin branch grows to 2 meters, lead the vine to the shed. This can improve the light transmission and ventilation conditions, reduce pests and diseases, and increase the sitting rate of melons by more than 40%.
Method three, prevent pumpkin leggings: If the pumpkin leggings will also cause less fruiting, such as cutting a crack on the vine 30 cm from the root, plugging charcoal, you can inhibit leggings. At the same time, we must pay attention to control the amount of nitrogen fertilizer applied, and increase the application of phosphorus and potassium fertilizers.
Method four: Auxiliary pollination of pumpkins: First, the female flowers that are about to open for pollination are covered with melon leaves to prevent the intrusion of rainwater. At 9 o'clock the next morning, the male flowers on the different plants are picked to cover the female flowers and removed after 3 days.
Method five: Remove the yellow leaves of pumpkin: on the flowering and fruiting melons, remove the foot leaves and old yellow leaves in time, and remove 30% of the male flowers, which can not only ventilate and transmit light, but also reduce the consumption of nutrients.
