蚕豆与芸豆对比. They are common legumes in our daily lives. The major suppliers of these beans worldwide are mainly located in countries such as Australia, France, the UK, 埃塞俄比亚, 加拿大, Mexico, and Argentina. 在中国, regions like Jiangsu, 安徽, and Hubei provide a stable supply of broad beans. 此外, areas with higher altitudes, such as Gansu and Qinghai, are also major producers of broad beans. On the other hand, hebei, Shanxi, 内蒙古, 吉林, and Heilongjiang are the main regions for kidney bean production. 尤其, China is the world’s third-largest producer of kidney beans.
What are the major production areas for broad beans and kidney beans, 无论是在全球还是在中国?
The main production areas for broad beans and kidney beans are as follows:
- Broad Beans: Broad beans originated in Southwest Asia and North Africa. 今天, they are cultivated and distributed worldwide, primarily in Europe, Asia, and Africa. China is the largest producer of broad beans globally.
- 芸豆: Originally from Central and South America, kidney beans later spread to Europe and Asia, becoming a global crop. Major producing countries include China, the United States, Argentina, Mexico, the UK, 日本, 印度, and Brazil. 在中国, kidney beans are widely grown across various regions.
Now, let’s look at their main production areas within China:
- Broad Beans: Primarily grown in the southwest, the Yangtze River basin, and the northwest regions, including Yunnan, Sichuan, Chongqing, Hubei, 甘肃, and Qinghai.
- 芸豆: Primarily distributed in the northeast, north, northwest, and southwest regions, such as Heilongjiang, 吉林, 内蒙古, hebei, Shanxi, Shaanxi, 甘肃, Xinjiang, Sichuan, Guizhou, and Yunnan.
These regions have suitable climates and soil conditions, making them the major production areas for broad beans and kidney beans.
What are the planting methods for broad beans and kidney beans?
After understanding their production areas, let’s learn about their planting methods.
Broad Beans:
- Soil Selection: Choose loose, fertile, and well-drained soil.
- Seed Treatment: Soak the seeds for 12 到 24 hours before sowing to improve germination rates.
- Sowing Method: Direct sowing or transplanting. Direct sowing involves scattering seeds directly in the field, while transplanting involves growing seedlings in nursery boxes and then transplanting them into the field.
- Management Practices: Keep the soil moist, weed in time, apply sufficient base fertilizer, provide timely top-dressing, and control pests and diseases.
芸豆:
- Soil Selection: Fertile soil with good aeration and deep soil layers, with convenient irrigation and drainage.
- Seed Treatment: Select large, plump, uniform seeds with consistent luster, free of pests and damage. Dry and soak the seeds before planting, followed by chemical treatment.
- Sowing Method: Either monocropping or intercropping. Monocropping requires ridging, with appropriate row and plant spacing. Intercropping involves planting alongside other crops, and adjusting planting density according to the characteristics of the companion crop.
- Management Practices: Keep the soil moist, weed, and ridge in time, stake the plants, plant at an appropriate density, apply timely top-dressing, and control pests and diseases.
What are their respective yields?
- Broad Beans: Under normal planting conditions, the yield of fresh broad beans is generally around 150 到 200 kg per mu (大约 0.067 hectares), with high-yield instances reaching up to 280 kg per mu. 例如, in Qujing City, high-yield demonstration plots can average between 250 和 290 kg per mu.
- 芸豆: When grown in sunny, warm environments, the yield can reach approximately 2,650 kg per mu. In Zhi Jin County’s high-yield demonstration base, the average yield ranges from 133.42 到 148.65 kg per mu, with the highest recorded yield at 163.97 千克.
Which is more nutritious?
To determine which bean is more nutritious, let’s look at their specific nutritional components.
Broad Beans:
- Vitamins: Rich in various vitamins, including vitamins A, K, C, 乙, B1 (硫胺素), B2 (riboflavin), and niacin. The vitamin C content is particularly high, with about 16 到 30 mg per 100 grams of broad beans.
- 矿物质: 钙含量高, 磷, 钾, sodium, 镁, 铁, zinc, selenium, copper, and manganese. Phosphorus and potassium levels are notably high, with approximately 200 mg of phosphorus and 391 到 801 mg of potassium per 100 克.
- 胖的: Relatively low fat content, with about 1.00 到 1.6 grams per 100 克.
- 膳食纤维: Contains a good amount of dietary fiber, aiding in intestinal health, with about 1.9 到 3.1 grams per 100 克.
- Sugars: Higher sugar content, typically around 61.5 grams per 100 克, primarily in the form of carbohydrates (58.9 到 59.8 grams per 100 克).
芸豆:
- Vitamins: Rich in vitamins, especially B vitamins and vitamin C, which is about 9 mg per 100 克. It also contains vitamins A, 乙, B1, B2, and niacin.
- 矿物质: Contains significant amounts of minerals, particularly calcium, 铁, and phosphorus. Calcium content ranges from 88 到 349 mg per 100 克, phosphorus from 37 到 400 毫克, and iron from 1 到 2.8 毫克. Also contains zinc and magnesium.
- 胖的: Low fat content, 大约 0.56 到 1.4 grams per 100 克.
- 膳食纤维: High in dietary fiber, promoting gastrointestinal health, with about 7.4 grams per 100 克.
- Sugars: Moderate sugar content, primarily in carbohydrate form, 大约 22 到 57.4 grams per 100 克, with lower sugar levels of about 0.3 到 6.4 克 (depending on variety and ripeness).
Both beans have distinct nutritional advantages, making it difficult to declare one as definitively better than the other; it largely depends on individual dietary needs.
例如, kidney beans are known for aiding digestion, weight loss, blood enrichment, spleen health, lowering blood sugar, and protecting blood vessels. Broad beans benefit brain and nerve health, enhancing memory and cognitive function. 此外, broad beans are low in calories, and suitable for individuals with high cholesterol or hypertension. They also have effects on energy boosting, spleen health, and reducing edema.
Ultimately, the choice between kidney beans and broad beans can be based on personal nutritional needs and health conditions.

How to Choose the Best Fava Beans and Kidney Beans?
Having gained a comprehensive understanding of fava beans and kidney beans, I would like to share how we should select the best fava beans and kidney beans. We can choose based on their color, shape, and texture.
Fava Beans:
- 颜色: Fava beans should be a bright green color, with the brighter, the better. If the fava beans come with pods, the pod skin and the sides should also be green. At the same time, avoid purchasing artificially dyed fava beans; you can blow gently on the fava beans and lightly squeeze them to see if the color comes off.
- Shape: Fava beans should be flat and round; choose full and round fava beans, as these are fresher and have better taste. Avoid selecting shriveled or incomplete fava beans.
- Texture: Good fava beans should be hard and not easily squished. If the fava beans feel soft when squeezed, it indicates they are no longer fresh or of poor quality, which will negatively affect their taste.
芸豆:
- 颜色: High-quality kidney beans are usually bright and uniform in color; for instance, white kidney beans should be pure white, and red kidney beans should be bright red. Avoid choosing kidney beans that are dull in color or have spots. The surface of kidney beans should have a certain natural luster, indicating that they are fresh and well-preserved. If the surface of the kidney beans is dull, it may indicate they have been stored for a while.
- Shape: High-quality kidney beans should be plump and rounded without obvious dents or deformities. Such kidney beans are more likely to maintain their integrity when cooked, resulting in better taste. Choosing evenly sized kidney beans ensures uniform cooking, avoiding cases where some kidney beans are overcooked while others are undercooked.
- Texture: Gently squeeze the kidney beans; if they feel firm and are not easily crushed, it indicates they are fresh and of good quality. If the kidney beans feel soft or have a hollow sensation, it may indicate they have deteriorated or been stored for too long. While it is not possible to directly assess the cooking taste through appearance, generally, high-quality kidney beans will retain a certain chewiness and delicious flavor after cooking. If the kidney beans become overly mushy or taste poor after cooking, it may suggest poor quality or improper cooking methods.
总之, by carefully observing the color and shape of the kidney beans and gently squeezing them to feel their texture, you can select high-quality fava beans and kidney beans.
