Causes of non-flowering of beans and its solution

Beans are a kind of vegetable that many people like, which are basically planted in rural areas. Under suitable conditions, it only takes about 45-60 days for sowing to blossom, but if they do not blossom beyond this period of time, it may be necessary to find a reason. So what causes beans not to blossom? Let's get to know it.

1. Fertilizer and water

The yield of beans is high, and the demand for fertilizer and water is large. The lack of fertilizer and water in our country may lead to non-flowering, but excessive fertilizer and water at flowering stage will cause branches and leaves to grow, resulting in insufficient nutrition for flowering, resulting in non-flowering. Therefore, in the fertilizer and water management of beans, we should pay attention to the combination of control and promotion, and properly adjust the fertilizer and water, so as to balance the vegetative growth and reproductive growth of beans, so as to achieve the goal of not flourishing and blooming early. Generally speaking, fertilizer and water should be properly controlled at the seedling stage, the base fertilizer is mainly organic fertilizer, and the amount of water and organic fertilizer should be increased at flowering stage.

2. Temperature

Beans are heat-resistant but not resistant to frost. the suitable temperature during flowering and podding period is 25-28 degrees. When the temperature is higher than 35 degrees, the beans will appear premature senescence, resulting in more flowers and pods, but when the temperature is lower than 10 degrees, the flower bud differentiation is slow. Therefore, attention should be paid to temperature regulation, it is best to ensure timely, temperature regulation should be paid attention to in greenhouse cultivation, open greenhouse film at high temperature, ventilation and ventilation, reduce temperature, cover grass curtain at low temperature, increase temperature and warm it, so as to promote its normal growth.

3. Lighting

Beans have two responses to the length of light, one is not strict with sunlight, and the other is more strict, which is suitable for cultivation in short-day environment. If you are planting this short-day bean variety, the light duration of the planting environment is relatively long, and there will often be the phenomenon of long stems, delayed flowering and pod bearing, and proper shading for this phenomenon, which is beneficial to its early flowering and pod bearing.

4. Self-cause

Beans in the high temperature season, when the first crop peak, there will often be a rest phenomenon, when the plant will blossom and bear pods greatly reduced. If it is because of the rest, then it is necessary to strengthen fertilizer and water management, and the plant will produce a large number of lateral vines in the axils of the leaves in the lower part of the plant, draw out inflorescences, blossom and bear pods, restore vitality and have a second yield peak.

The above is the introduction of the reasons and solutions for the non-flowering of beans. I hope I can help you. If you want to know more about it, please pay attention to us.
