In the past visits to the countryside, it was found that many farmers planted a lot of pumpkins, but often did not sit on the melons, so the yield of pumpkins was low. Therefore, the seed net has arranged the reason why the pumpkin light does not bear the knot and the countermeasures. The following is a detailed list for reference.
The reason why the pumpkin blossoms but does not bear the melon:
Pumpkin blossoming but not sitting on the melon is mainly due to insufficient sunlight, or excessive nitrogen fertilizer, and may also be due to a number of factors such as insufficient pollination of pumpkin, resulting in fewer pumpkins and more melons.
How to make pumpkins sit more:
Method 1: Picking up the pumpkin at the right time: When the pumpkin vine grows to 2 meters, pick up the growth point of the main vine, so that the main vine grows 3 to 4 branches and grows the knot.
Method 2: Support the scaffolding for the pumpkin: When the 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 long: If the pumpkin melon grows long, it will cause less melons. For example, if a crack is cut 30 cm from the root on the vine, the charcoal can be blocked. 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: Firstly, the female flower that is open and pollinated is covered with melon leaves to prevent rainwater from invading. At 9:00 the next morning, the male flowers on the different plants are taken out on the female flowers, and then removed after 3 days.
Method 5: Remove the yellow leaves of the pumpkin: on the melons that have been flowering, remove the leaves and the old yellow leaves in time, and remove 30% of the male flowers, which can both ventilate and reduce the consumption of nutrients.
