Do beans need top dressing when they are in bloom? (What fertilizers are needed for beans during the fruiting period)

Green beans, also known as cowpeas, generally have higher yields in summer. Green beans are also grown in greenhouses in winter. Their growth requires good light and humidity.

Can I still apply fertilizer after beans have formed horns?

Generally, after beans bloom, you can choose to fertilize them in the morning, when the temperature is more suitable and can help the plants absorb more nutrients. At the same time, you should pay attention to fertilizing too frequently. It is best to fertilize every ten days to avoid shortening the flowering period of beans.

In addition, during the fruiting period of beans, scientific fertilization is also necessary for the growth of beans. So how should we fertilize beans reasonably during planting? Especially after the beans have pods, is it necessary to apply topdressing?

①Base fertilizer

The base fertilizer of beans is the guarantee for the early growth. The base fertilizer is a mixed fertilizer, mainly farmyard manure, combined with water-soluble fertilizer and microbial agents, applied to the soil.

Apply base fertilizer when preparing the land and making ridges. Do not let the bean seedlings come into direct contact with the fertilizer when applying fertilizer. It is best to keep a distance of 15 cm from the fertilizer ditch to avoid root burn.

② Topdressing

Green beans need to be fertilized several times during their growth process. At this time, it is generally better to choose water-soluble fertilizers. Water-soluble fertilizers are highly water-soluble and have higher nutritional content, which can allow the green beans to fully absorb and play a role in weight loss and efficiency improvement.

Different fertilizers are needed at different growth stages of beans. Balanced water-soluble fertilizers are generally used from the seedling stage to the flowering stage, while high-phosphorus and high-potassium water-soluble fertilizers are used in the later stages. Such reasonable fertilization can promote the yield of beans.

Top dressing is required before and after beans form pods. This period is when beans require a large amount of fertilizer. It is necessary to increase the amount of phosphorus and potassium fertilizers applied to promote the transport of nutrients to the fruits.

③ Foliar fertilizer

In addition to base fertilizer and topdressing, beans also need appropriate foliar fertilizer. Foliar fertilizer is generally used to supplement trace elements, which can avoid yellow leaves, falling flowers and other phenomena due to nutrient deficiency.
