Detailed Explanation of Broad Bean Field Management Techniques

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 beans? How should field management be carried out during the process of growing broad beans? Let us learn about it together below.

1. Reasonable drainage and irrigation

Broad bean has the characteristics of liking moisture, fearing waterlogging, and fearing flooding, so when we grow broad beans, we need to do a good job in field water management. First, we should choose a suitable planting site, and the drainage and permeability of the planting site should be good; second, we should keep the soil moist, and when the soil is dry, we should water quickly, not irrigate slowly, and the amount of watering should not be too large. We need to water according to weather conditions and the water requirements of broad bean at its different growth stages. In addition, in rainy weather, or during heavy rain or continuous rain, we should still promptly drain excess water from the field to avoid triggering diseases and causing reduced yield and lower quality of broad beans.

2. Scientific fertilization

In the process of growing broad beans, fertilization is a very important step in field management work. The principle for fertilizing broad beans 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 beans, we mainly use nitrogen fertilizer to promote the overall growth of the plant and help promote flowering. When broad beans enter the flowering stage, we mainly use a ternary compound fertilizer for topdressing, and it also needs to be used together with a small amount of nitrogen fertilizer. When broad beans form 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 and topping

To ensure high yield and high quality of broad beans, proper trimming of branches and leaves 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, if we want a high yield of broad beans, we must promote the growth of branches. 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. 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 aeration and light penetration in the field, properly 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 beans, that is, after sowing broad beans but before they sprout, use a specialized herbicide for field crops to weed. At this time, the weeding effect is very good. After broad bean seedlings emerge, we can no longer use chemical agents for weeding, so we can only carry out intertillage weeding, which can also properly aerate the soil, improve the conversion rate of nutrients, and promote the growth of broad beans.
