How long does it take for peanuts to mature after flowering for harvest
Compared to the common knowledge of how long it takes for peanuts to mature after flowering and some small experiences in green plant maintenance throughout the entire growth process of peanuts, let's take a look together!
I. Peanut Planting Time
The planting time of peanuts mainly depends on the climate and variety. Generally speaking, peanuts can be planted in spring and summer. Spring planting usually occurs between February and April, when the temperature gradually warms up and the soil moisture is moderate, which is conducive to seed germination and growth. Summer planting is between May and June, when the weather is warm and rainy, peanuts grow fast, but attention should be paid to preventing drought and waterlogging.
In addition, the planting time of peanuts also needs to consider soil temperature and humidity. Generally speaking, when the soil temperature is stable above 15℃ and the soil moisture is moderate, it is the best time to plant peanuts. If the soil temperature is too low or the humidity is too high, it can lead to seed decay or poor growth.
II. Peanut Growth Period
The growth period of peanuts includes four stages: germination, seedling, flowering, and maturity.
1. Germination stage: It usually takes 5-10 days from sowing to seedling emergence. This stage is mainly seed absorption, expansion, and germination, with cotyledons breaking through the soil. The management focus at this time is to keep the soil moist, prevent soil from being too dry or too wet, and also prevent soil compaction and pest and disease attacks.
2. Seedling stage: It usually takes 20-30 days from emergence to the beginning of flowering. This stage is the vegetative growth period of peanuts, mainly focusing on the growth of roots and stems. The management focus at this time is to promote root development and stem and leaf growth, which requires timely fertilization and weeding, as well as preventing and controlling pests and diseases.
3. Flowering stage: It usually takes 40-50 days from the beginning of flowering to the end. This stage is when both vegetative and reproductive growth occur, mainly focusing on flowering, pollination, and pod formation. The management focus at this time is to strengthen fertilization and water management, promote flowering, pollination, and pod formation, and prevent and control pests and diseases.
4. Maturation stage: It usually takes 30-40 days from the beginning of maturation to full maturity. This stage is mainly for pod filling and seed maturity. The management focus at this time is to prevent premature aging and pest and disease attacks, and to harvest and dry the peanuts at the right time.
The growth period of peanuts is also affected by factors such as variety, climate, and soil. Different varieties of peanuts have slightly different growth periods, with shorter periods in warm and rainy areas and longer periods otherwise. Soil fertility and good drainage are beneficial to the growth and development of peanuts.
During the growth period of peanuts, the following issues also need attention:
1. Fertilization: Peanuts require a lot of fertilizer, especially phosphorus and potassium fertilizers have a significant impact on the growth of peanuts. Sufficient base fertilizer should be applied before sowing, mainly organic fertilizer, combined with phosphorus and potassium fertilizers; during the growing period, top-dressing should be applied in a timely manner according to the growth situation to meet the nutrient requirements of peanut growth.
2. Weeding: Weeding should be done in a timely manner during the growth of peanuts to prevent weeds from competing with peanuts for nutrients and water. Manual weeding or chemical herbicides can be used, but attention should be paid to the selection and application methods of herbicides to avoid damaging the peanuts.
3. Pest and Disease Control: Common peanut pests and diseases include root rot, leaf spot, aphids, etc., which should be detected and controlled in a timely manner. Biological control, agricultural control, and chemical control methods can be used, but attention should be paid to using low-toxicity and low-residue pesticides to avoid environmental and health impacts.
4. Harvesting and Drying: When the peanut plants turn yellow and the pods become hard, it is time to start harvesting. During harvest, care should be taken to avoid pod damage and soil contamination, and drying should be done in a timely manner to prevent moisture and mildew. Proper ventilation should be maintained during drying, and direct sunlight should be avoided to ensure peanut quality and storability.
In summary, peanut planting time and growth period are one of the key factors affecting peanut quality and yield. Mastering the planting time and growth period of peanuts, and arranging planting plans and management measures reasonably can improve peanut yield and quality, and increase farmers' economic income. It also helps to promote peanut planting techniques and facilitate the sustainable development of agricultural production.
