**I. Cultivation Conditions**
Peanut farming should be established in areas with clean air, meeting national air quality standards. The soil should be loamy or sandy clay, loose, well-structured, and have good drainage. Irrigation water must be free from contamination, and the overall environment should support high-quality, sustainable peanut production.
**II. Variety Selection**
Choosing the right peanut variety is crucial for success. Varieties such as Fenghua No. 5, Huayu No. 22, Huayu No. 24, and Huayu No. 21 are recommended due to their high yield, good quality, and resistance to pests and diseases. These varieties are well-suited for different growing conditions and can adapt well to local climates.
**III. Crop Rotation**
To maintain soil fertility and reduce pest and disease buildup, it’s important to rotate peanuts with other crops like wheat, corn, sweet potatoes, or vegetables every 2–3 years. After harvesting the previous crop, fields should be cleaned thoroughly to prepare for the next planting season. This practice helps prevent nutrient depletion and improves long-term productivity.
**IV. Fertilization**
For optimal growth, apply a balanced mix of organic and inorganic fertilizers. A typical recommendation is 15,000–22,500 kg of fully decomposed organic manure per hectare (with at least 0.2% nitrogen), along with 75 kg of biofertilizer and 300 kg of a triple compound fertilizer (N, P, K each at 15%). For soils with higher organic matter content, use 11,250 kg of organic-inorganic compound fertilizer per hectare. This ensures proper nutrition and supports healthy plant development.
**V. Sowing Techniques**
1. **Seed Selection and Preparation**
Use high-quality seeds that are clean, full, and disease-free. Seed germination should exceed 80%, with a purity of over 95%. Soak the seeds in warm water (around 40°C) for 30 hours to improve moisture absorption. Dry them in the shade before sowing. Applying trace elements like molybdate and borax through soaking or foliar spray can further enhance growth and yield.
2. **Planting Methods**
Planting should occur when the ground temperature stabilizes between 15–18°C, typically in late March to early April for spring peanuts and mid-May for summer planting. Use double-row ridge planting with plastic mulch to improve soil warmth and moisture retention. Sow two seeds per hole, with a density of about 9,000 holes per mu. Proper seed depth and tight film coverage help ensure good emergence and early growth.
**VI. Field Management**
1. **Seedling Care**
After emergence, cover the seedlings with a small mound of soil to protect them from exposure. This helps the cotyledons break through the membrane and establish strong growth.
2. **Mid-Season Management**
- **Flowering and Podding**: Ensure adequate water during flowering to avoid stress. If soil moisture drops below 50% of field capacity, irrigate immediately. Apply additional nutrients if leaf color changes or growth slows.
- **Needle Control**: Adjust soil ridges to create an "N" or "W" shape, which helps control pod development by reducing fruit needle elongation and improving airflow.
3. **Post-Fruiting Care**
- **Leaf Protection**: Spray a 1–2% urea solution or 2–3% superphosphate solution every 7–10 days to maintain leaf health.
- **Watering and Drainage**: Reduce irrigation during ripening, but ensure enough moisture if soil dries out. Avoid waterlogging to prevent rot and pests.
**VII. Integrated Pest and Disease Control**
Common issues include leaf spot, viral diseases, and nematodes, along with pests like aphids and bollworms. Use eco-friendly methods such as biological pesticides and cultural practices. For example, apply phoxim EC for grubs, anti-indolyl WP for locusts, and chlorothalonil for leaf spot. Root-knot nematodes can be controlled using Arlandia microemulsion. Always follow safety guidelines to protect both plants and the environment.
**VIII. Timely Harvesting**
Harvest when the plants turn yellow and the pods mature. Early harvesting may reduce yield and quality, while late harvesting increases the risk of pod drop and spoilage. Monitor the field regularly and harvest promptly to maximize yield and quality.
