What to Do About Flower Drop During the Flowering Period of Hyacinth Beans? A Full Analysis of the Latest Prevention and Control Measures
The hyacinth bean has a flat appearance, shaped much like a crescent moon, which is why it is called the hyacinth bean. It is not only attractive in appearance but also excellent in taste, and it is highly nutritious. It is grown in many regions, but many farmers have found that hyacinth beans are highly prone to flower drop during the flowering period, which seriously affects the number of pods the hyacinth bean sets. So how can flower drop in hyacinth beans be reduced? Let's take a look together.
1. Temperature regulation
The flowering period of the hyacinth bean is extremely delicate, and the temperature must be kept stable. If the temperature is too high or too low, it will have a huge impact on the flowers. If the low temperature falls below 15 degrees, the flowers will suffer cold damage, their ability to absorb nutrients will decline, and their growth will be greatly restricted, so flower drop occurs. If the temperature is above 28 degrees, the flowers will lose a large amount of water, gradually wither, and fall off before long. Therefore, during the flowering period of the hyacinth bean, the temperature must be well regulated so that it grows at a suitable temperature and produces more flowers.
2. Bagging
The flowers of the hyacinth bean are not particularly firmly attached, and they will be damaged when affected by strong winds during the flowering period. At this time, the absorption capacity of the damaged flowers will decline severely, and some damaged parts of the remnants will rot. After rotting, they will fall off and cannot set fruit. Moreover, after rotting, they will leave behind a large amount of pathogens, causing even greater harm to the plant. Therefore, before strong winds arrive, the hyacinth bean flowers can be covered with bags to protect them from damage, and after the strong winds pass, the bags can be removed so that the flowers can form pods normally.
3. Strengthen fertilizer and water management
The hyacinth bean blooms one after another, and after each part blooms, nutrients must be supplemented in time. There is no excessively high requirement for nutrients; it is enough to appropriately broadcast some urea at flowering time, and after the plant absorbs it, it will grow very well. As the flowers and pods grow, the plant's nutrient consumption increases, and there may be insufficient supply to the plant, leading to the appearance of some old leaves and yellow leaves. These leaves have low photosynthetic efficiency and cannot synthesize and transport nutrients very well, so the number of flowers and pods will be severely reduced. Watering during the flowering period of the hyacinth bean is also rather particular. At the beginning of flowering, the flowers are using their own nutrients to grow, so it is best not to water. After pods have formed, watering can be done appropriately to allow more flowers to bloom.
