Which peanut has the highest oil yield? Revealing high-oil peanut varieties and influencing factors
Recently, the topic of peanut oil yield has triggered heated discussions in the fields of agriculture and food processing. As the demand for edible oil grows, farmers and processing companies are paying attention to the selection of high-oil peanut varieties. This article will combine popular discussion data across the Internet to analyze the key factors affecting peanut oil yield and provide structured data comparison.
1. Top 5 popular high-oil peanut varieties (search popularity in the past 10 days)
| Ranking | Variety name | average oil yield | Main planting areas |
|---|---|---|---|
| 1 | Luhua No. 11 | 52%-55% | Shandong, Henan |
| 2 | Zhonghua No. 16 | 50%-53% | Hubei, Anhui |
| 3 | Yuhua No. 22 | 49%-52% | Henan, Hebei |
| 4 | Guangdong Oil No. 7 | 48%-51% | Guangdong, Guangxi |
| 5 | Jihua No. 4 | 47%-50% | Hebei, Liaoning |
2. Analysis of key factors affecting peanut oil yield
According to experimental data recently released by agricultural experts, the following factors have a significant impact on peanut oil yield:
| Influencing factors | degree of influence | optimal conditions |
|---|---|---|
| Breed genetic characteristics | Decisive factors (40%-60%) | Choose high-oil special varieties |
| soil type | 15%-20% | Sandy loam soil (good air permeability) |
| Growing season climate | 10%-15% | The temperature difference between day and night is large during the mature period |
| Harvest time | 8%-12% | When the leaf yellowing rate reaches 80% |
| Storage conditions | 5%-10% | Moisture ≤8%, low temperature drying |
3. Practical techniques to improve oil production rate (recent hot discussion)
1.Late harvest at the right time:The latest research shows that appropriately delaying harvest for 5-7 days can increase oil accumulation by 3%-5%, but care must be taken to avoid frost.
2.Scientific drying:After harvesting, the "progressive drying method" is used, first drying in the shade for 2 days and then exposing to the sun. The oil yield is 2%-3% higher than that of direct exposure.
3.Precise fertilization:Additional application of potassium fertilizer (potassium oxide 150-180kg/ha) during the pod-bearing stage can increase the oil yield by 1.5%-2%.
4. Comparison of oil yield rates of different processing methods
| Processing technology | average oil yield | Oil quality | Equipment cost |
|---|---|---|---|
| Traditional pressing | 42%-45% | Excellent (retains fragrance) | low |
| screw press | 48%-52% | good | in |
| solvent leaching | 55%-58% | Needs refining | high |
| Low temperature cold pressing | 38%-42% | Premium (Nutritional Retention) | high |
5. Market conditions and planting suggestions (updated in the past 10 days)
1.Price trends:The purchase price of high-oil peanuts (oil yield ≥50%) is generally 15%-20% higher than that of ordinary varieties, and market demand continues to grow.
2.Variety selection:The Luhua series is recommended in northern areas, and the Yueyou series disease-resistant varieties are recommended in hot and humid southern areas.
3.Policy support:Many places have introduced subsidy policies for high-oil peanut cultivation, with subsidy amounts ranging from 150 to 300 yuan per mu.
4.Risk warning:High-oil varieties generally have weak lodging resistance and need to be strengthened in field management. It is recommended to purchase agricultural insurance.
Summary:Selecting high-oil peanut varieties suitable for the local climate, combined with scientific planting and processing technology, can significantly improve economic benefits. It is recommended that farmers refer to the latest agricultural technology extension data and choose the optimal planting plan based on their own conditions.
