How long is the growth cycle of watermelon?
Today's tip about life: the growth cycle of watermelon is how long, green plant and flower planting content, the following for you to introduce in detail
How long is the growth cycle of watermelon?
After planting, watermelon goes through four stages: germination, growth, flowering, and fruiting. At a soil temperature of 15-20°C, the germination period takes about 7-13 days. At suitable temperatures, the seedling stage takes about 25-30 days, the vine elongation stage needs 18-20 days, and the fruiting stage takes 28-40 days. Watermelon is adaptable, with early-maturing varieties requiring 80 to 90 days from seedling to maturity; mid-maturing varieties need 90 to 100 days; late-maturing varieties take 100 to 120 days.
Brief introduction to watermelon growth
Watermelon is adaptable and prefers to grow in warm, loose, deep, and well-drained sandy soil. Currently, watermelon production areas in China are divided into the north and south: the southern region, with Hainan Island as the main production area, and the northern region, with Shandong as the main production area.
Watermelon growth cycle
Early-maturing watermelon varieties require 80 to 90 days from seedling to maturity; mid-maturing varieties need 90 to 100 days; late-maturing varieties take 100 to 120 days. Its growth period is long, so it requires a large amount of nutrients.
Watermelon growth rate
After planting, watermelon generally goes through four stages: germination, growth, flowering, and fruiting, and finally, it ages and dies. At a soil temperature of 15-20°C, the germination period takes about 7-13 days. At suitable temperatures, the seedling stage takes about 25-30 days, the vine elongation stage needs 18-20 days, and the fruiting stage takes 28-40 days.
Watermelon growth cycle management
If watermelon is well cultivated, the yield of large watermelons can reach 7000-10000 jin per mu, the yield of medium-sized watermelons can reach 6000 jin, and the yield of small watermelons can reach 3000-5000 jin per mu.
The growth momentum of watermelon in the early stage is relatively poor, and the plant gradually returns to normal in the later stage. If it cannot fruit in time, it often causes excessive growth. Although small watermelons have a weaker growth momentum, they have a strong branching ability and many lateral branches.
Temperature management: The optimal growth temperature for watermelon is between 25-30°C, with an adaptive range of 10-40°C. The total accumulated temperature during the entire growth period is 2500-3000°C. Watermelon has different temperature requirements during different growth stages.
Fertilization management: Watermelon seedlings absorb less nitrogen, phosphorus, and potassium, with the highest absorption during the fruit setting and fruit growth stages. Do not apply fast-acting nitrogen fertilizer during the flowering and fruit-setting period.
