What are the latest fertilization methods for green beans?

Green beans are a very common dish in daily life. Whether stir-fried plainly 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. Although the yield of green beans on the market is already very high now, they are still very popular, and the price is also much higher than that of 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 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 decomposed fertilizer per mu, but if it is relatively barren, then at least 1,000 kg more fertilizer needs to be added to the application amount. For green beans with taller seedlings, the amount of fertilizer used 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 7 to 10 days after emergence and after replanting to fill gaps. This is because the green bean seedlings have basically survived by then, 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 let the green bean seedlings grow quickly, while the nutrients later will become increasingly thin, and that is when topdressing is the wisest choice. For many crops, seedling fertilizer uses nitrogen fertilizer, but the seedling fertilizer for green beans is mainly phosphate fertilizer, with an appropriate addition 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 nutrients required during the flowering period of green beans are also very high, and the nutrient supply during the flowering period is also a relatively critical period, because the number of flowers opened 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 per mu, and secondly, an appropriate topdressing of 20 jin of urea, which can prevent the green bean seedlings from aging, while also extending the flowering period and increasing the pod-setting rate.

4. Pod fertilizer

Pod fertilizer is applied about one week after the flowers fade. At that time, the green beans have gradually begun to show small outlines. In order to make the green beans grow fuller and without deformities, we need to spray some foliar fertilizer appropriately. It is mainly boron fertilizer, with about 35 jin of boron fertilizer required per mu, and secondly, an appropriate irrigation of some phosphate fertilizer and potassium fertilizer, which can promote the growth rate of the pods and improve the quality of the green beans.

5. Maintenance fertilizer

Since 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 before application. This can prevent the green bean seedlings from aging to a certain extent, causing yield reduction, and at the same time can promote the growth of new branches and leaves, as well as ripening and promoting the flowering period.
