2. In addition, in the flowering period of pumpkin, if it rains for a long time, which one will also cause the pumpkin to drop flowers. Long rainy days will affect the normal pollination in pumpkin flowers, especially the continuous rainy days, which will increase the difficulty of pumpkin fruit setting after flowering.
3. Due to the rainy weather and insufficient light, the development of ovary and flower organs in pumpkin flowers will be affected, and the rain will wash away the pollen on the stigma of the female flower of pumpkin, or the pollen will be broken, so pollination cannot be completed normally. In this case, it is necessary to strengthen artificial pollination.
Pumpkin is affected by temperature: the pumpkin we grow is actually very resistant to high temperature, but if the temperature is as high as 35-37 degrees, the plant will grow slowly. The temperature is above 38-40 degrees, so pay attention. If the temperature is too high, the pumpkin will not bear fruit, which is not conducive to the fruit.
Pollination effect of pumpkin: Although pumpkin is easy to plant, if it does not bear fruit after planting, it will be affected not only by temperature, but also by pollination. If pollination is not good, it will also affect the fruit setting rate. Generally, pumpkin pollination also depends on media pollination, such as bee pollination, insect pollination and wind pollination, but now there are too many insects in some crops in rural areas, so there are fewer insects than before, because there is no insect pollination. This also affects pollination and is easy to drop melons. You can also pollinate by hand if you can, but few people like these rural pumpkins will pass this operation, but the effect of this operation is really effective.
