Peanuts are grown throughout China. Generally, the growth cycle of peanuts is 100-150 days, with early-maturing varieties taking 100-130 days, medium-maturing varieties taking 135-150 days, and late-maturing varieties taking more than 150 days.
How many days is the growth cycle of peanuts?
The growth cycle of peanuts is approximately 100-150 days. Early-maturing peanut varieties typically have a growth period of 100-130 days. Mid-maturing varieties typically have a growth period of 135-150 days. Late-maturing varieties typically have a growth period of 150-160 days or more.
Peanut growth process
1. Germination and seedling emergence period
The germination and emergence period refers to the time from peanut sowing until 50% of the seedlings emerge from the soil and develop their first true leaf. The germination and emergence period is approximately 5-15 days. For spring-sown peanuts, it is generally 8-15 days, and for summer-sown peanuts, it is generally 5-10 days.
2. Seedling stage
The seedling stage refers to the period from when 50% of the seedlings emerge from the soil until 50% of the plants open their first flower. The seedling stage lasts approximately 20-35 days. For spring-sown peanuts, it generally lasts 25-35 days, while for summer-sown peanuts, it generally lasts 20-25 days.
3. Flowering and pegging stage
The flowering and pegging period refers to the time from when 50% of the plants have opened their first flower to when 50% of the plants have developed chicken-head-shaped pods. This period lasts approximately 15-35 days. For spring-sown peanuts, it is generally 25-35 days, while for summer-sown peanuts, it is generally 15-20 days.
4. Pod-setting stage
The pod-setting period refers to the time from when 50% of the plants have developed small, chicken-head-shaped pods to when 50% of the plants have developed full, plump pods. The pod-setting period lasts approximately 20-40 days. For spring-sown peanuts, it generally lasts 30-40 days, while for summer-sown peanuts, it generally lasts 20-30 days.
5. Fruit ripening period
The pod-filling maturity period refers to the time from when 50% of the plants have full pods until the vast majority of pods are full and mature. For spring-sown peanuts, the pod-filling maturity period is approximately 40-50 days. For summer-sown peanuts, the pod-filling maturity period is approximately 30-40 days.
