How much is the yield of green beans per mu? What is the investment cost of planting green beans per mu?

Green beans yield per mu

The yield per mu of green beans will be affected by factors such as season, planting method, and variety. Usually the yield per mu is around 1,500 jin. If properly maintained and managed, the yield per mu can generally reach around 2,000 jin.

Green Bean Planting Prospects

The cost of planting green beans is very low. The cost of purchasing seeds, land costs, labor costs, fertilizers, pesticides and other planting costs are at most around 2,000-2,500 yuan. The yield per mu of land is basically around 2,000 jin, and one mu of land can make a profit of about 8,000 yuan, with a net profit of about 5,000 yuan. The planting prospects are relatively good.

How to grow green beans for high yield

1. Planting time

If green beans are planted in a greenhouse, they can be sown in mid-February each year and planted directly in the field at the end of February, because the temperature and weather begin to warm up at this time, which is suitable for the germination and later growth of green beans.

2. Site preparation selection

Green beans do not have high requirements for soil and can be planted in loam and sandy soil, but you need to be careful to choose a piece of soil that is loose, fertile, and has strong water-retention and drainage properties.

3. Water management

Because green beans do not require much water and they like dryness and fear wetness, the soil needs to be watered. Just keep the soil moist. It is recommended to follow the method of watering when the soil is dry and watering when the soil is wet. In the rainy season, pay attention to the drainage of the fields and do not allow water to accumulate.

4. Fertilization management

Fertilization of green beans can be combined with watering. It is recommended to apply less fertilizer before flowering and more fertilizer after flowering. Heavy fertilization is needed during the pod-setting stage. Top dressing is needed in the early stage of the growth period. You can choose decomposed organic fertilizer mainly composed of nitrogen fertilizer. Decomposed organic fertilizer can be sprayed from the flowering period to the pod-setting period.

5. Field management

Large-scale weeding is needed half a month after sowing green beans to prevent weeds from competing with green beans for nutrients. A second large-scale weeding is needed when the green beans are climbing. When the green beans grow to about 17-25 cm, appropriate trellis construction is needed to promote their growth.
