The function of topping pumpkin is to adjust the plant type of disordered plants, coordinate nutrient distribution, ensure sufficient nutrients and improve plant yield and quality.

Pumpkin coring, also called topping, is a simple measure to increase crop yield, that is, removing the top of the growing plant, controlling plant growth and controlling nutrient supply.

Suitable time for core removal of pumpkin

When pumpkin seedlings grow to 8- 10 leaves, they can be pitted for the first time. At this time, enucleation can promote the growth of lateral branches and make nutrients more concentrated, which is beneficial to the later growth and development.

How high is the pumpkin?

Generally speaking, it is more suitable for adult pumpkin plants to be cored when the vine length is 2 ~ 3 m, which can adjust the growth state of the plants and improve the yield and quality.

Pumpkin core removal method

When picking pumpkins, we must first find a good location. The best location for picking pumpkins is about 15 cm away from the seedlings. Remove all the tender buds at the top of the branches and leaves and keep 15-20 leaves.

Precautions for removing the core of pumpkin

Pumpkin will leave a wound after removing the core, so when watering and fertilizing after removing the core, you can't directly water or fertilize the plant, nor can you splash water or fertilize the wound. After enucleation, you should avoid exposing plants to the sun to avoid the wound from rotting.

It is more suitable to apply compost, miscellaneous fertilizer and other decomposed farmyard manure after the pumpkin is pitted, which can provide sufficient nutrients for the plant to resume growth.
