What are the fertilization methods for green beans?

Green beans are a very common dish in daily life. Whether stir-fried plain or cooked in a dry pot, the taste is very good, and the nutrient content is also extremely high. In many families, it is a dish loved by men, women, the young and the old alike. Although the yield of green beans on the market is already very large now, they are still very popular, and the price is also much higher than some other vegetables. So today Qinnong.com will teach everyone a trick on how to fertilize green beans well.

1. Base fertilizer

For the application of base fertilizer for green beans, we need to choose according to the fertility level of the planting site and the variety of green beans selected for planting. If the soil is relatively fertile, then we only need to apply 4,000 kg of organic fertilizer or farmyard rotted manure per mu, but if it is relatively barren, then we need to increase the fertilizer application amount by at least 1,000 kg. The fertilizer amount for green beans with taller seedlings is also relatively higher, so on the basis of 5,000 kg we add about 100 kg of plant ash, or about 50 kg of phosphate fertilizer, while green beans with short seedlings do not need this.

2. Seedling fertilizer

Seedling fertilizer is generally applied about seven to ten days after emergence and after replanting to fill gaps, because at this time the green bean seedlings have basically survived, and it is best to apply it when the green bean seedlings are about 15 cm to 20 cm tall, because the earlier base fertilizer can also allow the green bean seedlings to grow rapidly, while the nutrients later will become increasingly thin, and that is when topdressing is the wisest choice. The seedling fertilizer for many crops uses nitrogen fertilizer, but the seedling fertilizer for green beans is mainly phosphate fertilizer, with an appropriate additional application of about 25 jin of nitrogen fertilizer, because too much nitrogen fertilizer will cause the green bean seedlings to grow excessively without forming pods.

3. Flower fertilizer

The nutrient demand during the flowering period of green beans is also very high, and the nutrient supply during the flowering period is also a relatively critical period, because the number of flowers also determines the yield of green beans to a certain extent. So during this period we mainly focus on adding fertilizer, with an average of about 30 jin needed per mu. Secondly, an appropriate topdressing of 20 jin of urea can be applied, which can prevent the green bean seedlings from aging, and at the same time can extend the flowering period and increase the pod-setting rate.

4. Pod fertilizer

Pod fertilizer is applied about one week after the flowers fade, when the green beans have gradually taken on a small outline. In order for the green beans to grow relatively plump and without deformities, we need to spray an appropriate amount of foliar fertilizer. It is mainly based on boron fertilizer, with about 35 jin of boron fertilizer needed per mu. Secondly, an appropriate amount of phosphate fertilizer and potassium fertilizer should be watered on, which can promote the growth rate of the pods and improve the quality of the green beans.

5. Maintenance fertilizer

Because green beans are harvested in batches, maintenance fertilizer is also relatively important for increasing the yield of green beans. It is generally applied after the green beans are harvested, mainly by watering with manure and urine water, and about 10 jin of urea can be added in the middle and stirred evenly for application. This can, to a certain extent, prevent the green bean seedlings from aging and causing reduced yield, and at the same time can promote the growth of new branches and leaves, as well as hasten ripening and promote the flowering period.
