How many days does it take for peanuts to germinate and emerge from the soil? How to plant them?
I. Time for Peanut Germination and Emergence from Soil Peanut seeds usually take 7-15 days to complete the whole process of germination and emergence under suitable conditions, with the specific time influenced by multiple factors: 1. Temperature factors (1) Germination temperature range: 15-30°C, optimal temperature 25-30°C (2) 18-20 days at a soil temperature of 15°C (3) 12-15 days at a soil temperature of 20°C (4) 5-7 days at a constant temperature of 30°C 2. Moisture conditions (1) Soil moisture should be maintained at 60-70% (2) Seeds treated with soaking can germinate 2-3 days earlier (3) Germination time extends to over 20 days under dry conditions 3. Variety differences (1) Early maturing varieties: Zhonghua series 5-7 days (2) Late maturing varieties: Luhua series 10-12 days (3)珍珠豆 type is 3-5 days earlier than the common type 4. Sowing depth (1) 3cm shallow sowing: 2-3 days earlier (2) 5cm standard depth: normal cycle (3) More than 8cm delayed by 5-7 days
II. Key Points of Scientific Cultivation Techniques 1. Seed selection and treatment (1) Selection criteria: Double kernel rate ≥ 95%, germination rate ≥ 90% (2) Sunning treatment: Sun the seeds for 2-3 days before sowing (3) Seed dressing with chemicals: 50% carbendazim mixed with 0.3% of the seed weight (4) Soaking and germination: Soak in warm water at 30°C for 6-8 hours 2. Land preparation requirements (1) Deep plowing standard: Autumn plowing 25-30cm, spring plowing 15-20cm (2) Soil moisture: able to form a ball in hand and disperse when dropped (3) Ridge specifications: Ridge width 80-90cm, ridge height 15-20cm (4) Fertilization standard: Apply 2000kg of decomposed organic fertilizer per mu plus 50kg of peanut special fertilizer 3. Timely sowing (1) Temperature indicator: 12°C stable soil temperature at 5cm depth (2) Suitable sowing period: - Southern regions: Late February to mid-March - Huaihe River Valley: Mid-April to early May - Northern regions: Mid to late May (3) Sowing density: - Upright varieties: 8000-10000 holes/mu - Creeping varieties: 6000-8000 holes/mu (4) Sowing depth: Sandy loam 3-5cm, clay 2-3cm 4. Field management (1) Checking seedlings and supplementing: Completed within 3 days after seedlings emerge (2) Shallow cultivation and weeding: - Shallow tillage of 3-5cm during the seedling stage - Tillage of 8-10cm during the flowering stage (3) Water management: - Maintain 70% moisture during the flowering and pinning stage - 55-60% moisture during the pod setting stage (4) Chemical control technology: - Spray 50mg/kg of paclobutrazol when the plant height is 35cm - Interval of 15 days for secondary regulation 5. Pest and disease control (1) Soil pests: Apply 5kg of 3% phoxim granules per mu before sowing (2) Leaf spot disease: Spray 50% carbendazim 800 times solution at the initial stage of the disease (3) Bacterial wilt: Choose disease-resistant varieties and rotate crops (4) Aphid control: Spray 10% imidacloprid 3000 times solution
III. Innovative High-Yield Cultivation Techniques 1. Mulching technology (1) Yield increase effect: Increase yield by 30-50% (2) Technical points: - Use 0.008mm microfilm - Mulch first, then punch holes for sowing - Compact the edge of the film with a thickness of ≥10cm 2. Interplanting patterns (1) Peanut and corn: 2:2 row ratio configuration (2) Peanut and watermelon: 3m planting strip (3) Interplanting under trees: Tree row spacing of 4m or more 3. Water-saving irrigation (1) Drip irrigation technology: Save water by 40%, increase yield by 15% (2) Small bed irrigation: Bed length not exceeding 30m (3) Key period irrigation: Flowering and pinning stage + pod setting stage 4. Timely harvesting (1) Maturity sign: 70% of the pods have clear net patterns (2) Harvesting period: Complete 10 days before the early frost (3) Drying standard: Reduce the moisture content of the kernels to below 8%
IV. Solutions to Common Problems 1. No seedlings emerging (1) Seed rot treatment: Disinfect with metalaxyl when replanting (2) Soil compaction: Break the crust by shallow raking after sowing (3) Bird control: Set up bird repelling tape or protective net 2. Yellowing seedlings (1) Nitrogen deficiency symptoms: Topdress with 5-8kg of urea per mu (2) Waterlogging treatment: Open ditches for drainage and spray foliar fertilizer (3) Mitigation of chemical damage: Spray 2000 times solution of brassinolide 3. Controlling excessive growth (1) Chemical regulation: Spray 20g of uniconazole per mu with water (2) Manual trampling: Trample the plants in the afternoon during the full bloom stage (3) Nutritional regulation: Reduce nitrogen fertilizer and increase phosphorus and potassium fertilizers By mastering the above key technical indicators and time points, and配合 fine management measures, it is possible to achieve a high yield target of 300-500kg per mu of peanuts. Note that different production areas should adjust the sowing period and variety selection according to local climate characteristics, and it is recommended to consult local agricultural technology departments for specific technical parameters.
