Latest Broad Bean Field Management Techniques and Methods Tutorial

Broad bean is also called fava bean, Buddha bean, luohan bean, orchid bean, etc. It is currently mainly distributed in Sichuan, Yunnan, Hunan and Hubei in China. Broad bean has strong adaptability to the growing environment and is a relatively easy plant to grow. So do you know how to grow broad bean? How should field management be carried out during the process of growing broad bean? Let's learn about it together below.

1. Reasonable irrigation and drainage

Broad bean has the characteristics of liking moisture, fearing waterlogging, and fearing flooding, so when we grow broad bean, we need to do a good job in field water management. First, choose a suitable planting site, and the drainage and permeability of the planting site should be good; second, keep the soil moist. When the soil is dry, water quickly, and do not use slow irrigation. At the same time, the amount of watering should not be too large. We need to water according to weather conditions and the water needs of broad bean at its living stages. In addition, in rainy weather, or during heavy rainfall or continuous rainfall, the excess water in the field should still be drained in time to avoid causing disease and causing reduced yield and lower quality of broad bean.

2. Scientific fertilization

In the process of growing broad bean, fertilization is a very important step in field management work. Our principle for fertilizing broad bean is generally an appropriate amount of nitrogen fertilizer, increased application of phosphate fertilizer and potassium fertilizer, and supplementation of micro-fertilizers. During the seedling stage of broad bean, we mainly use nitrogen fertilizer to promote the overall growth of the plant, which is beneficial for promoting flowering. When broad bean enters the flowering stage, we mainly use a three-element compound fertilizer for topdressing, and it also needs to be used together with a small amount of nitrogen fertilizer. When broad bean forms pods, we also mainly use compound fertilizer, and appropriately increase the application of phosphate and potassium fertilizers. Finally, after each harvest, spray foliar fertilizer in time.

3. Pruning branches and topping

In order to ensure high yield and high quality of broad bean, proper branch and leaf management as well as topping are very necessary. The main stem of broad bean does not bear pods, and even if it does bear pods, the yield is not high. Therefore, to achieve high yield in broad bean, the growth of branches must be promoted. Generally, we carry out pinching and topping treatment, that is, removing the heart leaves on the main stem to promote the growth of side branches, and when the side branches grow to a certain length, pinch them again until a complete plant shape is formed. Second, in order to maintain reasonable ventilation and light transmission in the field, appropriately thin out side branches that are too dense or growing poorly.

4. Timely weeding

Now there is actually a very simple way to weed broad bean, that is, after broad bean is sown but before it sprouts, use a specialized herbicide for field crops to weed. At this time, the weeding effect is very good. After broad bean emerges, we can no longer use chemical agents for weeding, so we can only carry out intertillage weeding. This can also properly aerate the soil, improve the conversion rate of nutrients, and promote the growth of broad bean.
