Planting pumpkins is often caused by lack of sunlight, excessive nitrogen fertilizer, lack of pollination and other reasons, resulting in fewer pumpkin flowers. In order to avoid the above phenomenon, the following measures can be taken to increase the output:
First, pick the top in due course. When the melon vine grows to 2 meters, the main vine growing point is removed, so that the main vine grows 3 to 4 branch vines, and the flowering pods grow.
Second, scaffolding. When the branch vine grows to 2 meters, the vine spreads on the shed, which can improve the light transmission and ventilation conditions, reduce the pests and diseases, and thus increase the rate of sitting cucumbers by more than 40%.
Third, prevent leggy. Melon vines will also cause less fruit, such as cutting a crack in the vine at a distance of 30 cm from the root, and block the charcoal, which will curb appetite. At the same time, we must also pay attention to controlling the amount of nitrogen fertilizer application and increasing the application of phosphorus and potassium fertilizers.
Fourth, auxiliary pollination. The female flowers that can be pollinated soon after opening are covered with melon leaves to prevent the intrusion of rainwater. At 9:00 the next morning, male flowers on different plants are taken to cover the female flowers and removed after 3 days.
Fifth, picking leaves. On the vines that have already blossomed, timely removal of the leaves of the foot and old yellow leaves, and the removal of 30% of the male flowers, can both ventilate the light and reduce the consumption of nutrients.
