In the recent visit, the author found that many farmers planted a lot of pumpkin flowers, but often did not fruit, resulting in low yield of pumpkin. The reason is mainly caused by insufficient sunlight, excessive nitrogen fertilizer, and insufficient pollination. The following methods are recommended to allow pumpkins to sit more:
Method 1: When the pumpkin vine grows to 2 meters, the main vine growth point is removed, so that the main vine grows 3 to 4 vines, and the flowering and cascading.
Method 2: Support the scaffolding for the pumpkin. When the pumpkin vine grows to 2 meters, the vine is placed on the shed, which can improve the light transmission and ventilation conditions, reduce the pests and diseases, and thus increase the sitting rate by more than 40%.
Method 3: Prevent the pumpkin from growing. If the pumpkin melon grows long, it will cause fewer melons. For example, if a crack is cut 30 cm from the root on the vine, the block charcoal can suppress the length. At the same time, we must pay attention to controlling the amount of nitrogen fertilizer applied and increasing the application of phosphorus and potassium fertilizer.
Method 4: Auxiliary pollination of pumpkin. First, the female flowers that are open to pollination are covered with melon leaves to prevent rainwater from invading. At 9 o'clock the next morning, the male flowers on the different plants are taken over the female flowers, and then removed after 3 days.
Method 5: On the melons that have been flowering, remove the leaves and old yellow leaves in time, and remove 30% of the male flowers.
