Pumpkin has a cool and humid climate, easy cultivation, large fruits, strong resistance, diverse varieties, strong adaptability, wide geographical distribution, high yield and storability, and different fruit shapes, sizes and qualities. It is widely planted in China and Northeast China, especially in Heilongjiang.

Pumpkin growth temperature

Pumpkin needs high temperature, and its suitable temperature is 18~32. At this temperature, the growth rate of plants is the fastest, and it should not be lower than 12~ 15, otherwise the growth rate will slow down.

Is pumpkin resistant to high temperature?

Pumpkin has strong high temperature resistance. Usually, it can withstand the high temperature of 46℃, but if the temperature is higher than 46℃, its growth will be hindered.

What is the minimum cold tolerance of pumpkin?

Pumpkins are warm. When the temperature is lower than 15, the growth is poor, and the lowest tolerance is 6℃. If the temperature of the growing environment is lower than 6, plants will suffer from freezing injury.

What temperature can pumpkin be planted?

Generally speaking, the environmental temperature of pumpkin planting is between 20 and 30, which makes it easier for its seeds to take root and sprout.

Pumpkin growth process

Germination period: generally, it takes 3 days for pumpkin to germinate after accelerating germination, 1-2 days for cotyledons to fully bloom, and 3-5 days for cotyledons to grow into real leaves. Seedling stage: the pumpkin grows from the first true leaf until there are 5-7 true leaves that can be wound around branches and leaves, and then enters the seedling stage. Vine-pulling period: Pumpkin enters vine-pulling period from the 5th-7th true leaf to the first pistil, which generally lasts 10- 15 days. Flowering and fruiting stage: it takes 50-70 days from the first female flower to the fruit maturity, and the roots, branches and leaves will go together with the flowering until the fruit matures.

Pumpkin planting method

The best soil for planting pumpkins is sandy loam, which is relatively breathable. Apply base fertilizer before sowing, mainly natural organic fertilizer. Pumpkin seeds need to be dried in the sun for two days before sowing, and then soaked in warm water for three hours to accelerate germination. After most seeds turn white, they can be planted in the soil.
