In rural areas, most people grow pumpkins, which is a relatively common vegetable. Pumpkin is not only a delicious vegetable, its seeds can be fried, and the vine can also be cooked. It can be said that the whole body is a treasure! But sometimes there are phenomena of falling flowers and fruits in the process of planting pumpkins. What are the main reasons? What preventive measures are there? Let me tell you the following small series!
First, the main reason for pumpkin falling flowers and fruit:
1, the early maturity of the pumpkin, the female flower first opened, no male flowers pollination, there will be no female, male flowering period, resulting in the failure to normal pollination.
2, early flowering, lower temperature, female flower dysplasia, pollen tube growth slow, poor pollination.
3, excessive application of nitrogen fertilizer or continuous rainy days, resulting in pumpkin gluttony weight, stems and leaves than the fruit growth, fruiting results in the nutritional guarantee, resulting in falling flowers and fruit.
4. The pumpkin is a cross-pollinated plant. If it encounters rainy weather during the flowering period, it cannot be pollinated normally, resulting in falling flowers and fruit.
5, too much cultivation density, resulting in field closure, poor permeability, is also one of the reasons for falling flowers and fruit.
Second, the preventive measures for the fall of the pumpkin
1. Regulate nutrition and reproductive growth
The vegetative growth is too strong. When the main vine is stretched to 12 knots and there is still no female flower, it is necessary to weaken the apical advantage and promote its vegetative growth to reproductive growth. There are many methods, one is to change the head, the main vine does not result, but the main vine is cut off before the leaf bud with the vine in the lowest part of the main vine. The closer the vine is to the root, the better. The melon is a vine with a melon; or a deep cultivating is carried out, and the root is broken.
2, thinning flowers and thin fruit
Because too many female flowers have once fallen, you can properly remove some of the flowers and fruits.
3, artificial pollination
Artificial pollination is easy to carry out at 8-10 in the morning. At this time, the pollen is mature, the strong male flower is removed, the petals are removed, and the anther is gently applied on the female flower. At this time, the mucus is secreted on the stigma and the male flower pollen is stuck. , complete pollination. A male flower can be used to give 2-3 female flowers in succession. After pollination, there should be a leaf cover to prevent rain from washing away the pollen, or a bee pollination.
4, reasonable close planting
In order to prevent the field from being closed, it is reasonable to plant 800-1200 plants per acre. The early maturity species can be properly planted, and the late-maturing species can be appropriately planted, which is beneficial to improve ventilation and light transmission, and improve fruit setting rate. The disease has occurred.
Ok, what I want to share with you today is here first. If the friends who planted pumpkins have fallen into the fruit, the main reasons are the above five reasons. The preventive measures can also be used to properly learn from this article! If you think it's not bad, collect this article!
