How to Increase Broad Bean Yields? A Full Breakdown of the Latest Techniques
Broad beans are fairly common in our daily lives. They can not only be eaten as a vegetable, but also processed into all kinds of small snacks, and both are well received by many people. Therefore, the area planted with broad beans is still very large nowadays, and when planting broad beans, how to increase the yield is certainly a question many people care about. So how exactly do you increase broad bean yields? Below, the editor will give you a brief introduction. Let's take a look together!
1. Remove the main stem
When planting broad beans, we should pay attention to removing the main stem of the broad bean plant at the right time. This concentrates all the nutrients in the secondary stems that branch out before overwintering each year. It encourages the secondary stems of the broad bean plant to increase flower numbers and pod set the following year. This achieves the goal of increasing broad bean yields. Generally, the time to remove the main stem is in January each year. It should not be too late, to avoid the secondary stems becoming overly mature and reducing the effect. When removing the main stem, simply cut it off at a point about 10cm above the ground; at the latest, this should be completed before mid-January.
2. Remove ineffective branches
Besides removing the main stem, we should also pay attention to properly removing some ineffective branches. This is because the branches that the broad bean plant sends out after the Beginning of Spring generally produce relatively few flowers. And even if they can flower, they very easily show the phenomenon of flowering without setting fruit. They also compete with the effective branches sent out before the New Year for light, water and fertilizer, seriously affecting the overall growth of the plant. So in March each year, at the early flowering stage of broad beans, remove the small branches and tender shoots in time, concentrate the nutrients on the effective branches, and increase broad bean yields.
3. Pinching
Broad bean flowers are mainly lateral short raceme inflorescences, and their flowering period is generally about one month. During the flowering and podding stage, if nutrients are not concentrated in supplying flowering and pod setting, the flowers and pods may drop due to lack of nutrients. Infertile flowers also easily appear at the tips of the branches, so in the later stage we should also pinch off the growing tips at the right time, control plant growth, and increase broad bean yields. This should generally be done after Qingming Festival, and mainly should be reasonably controlled according to the actual growth of the broad beans, to avoid harming the broad bean plants.
4. Water and fertilizer management
Broad beans generally like to grow in a relatively moist environment. However, they have poor waterlogging tolerance, so we should pay attention to watering properly. In the early growth stage of broad beans, keep the soil moist to promote seed germination. In the middle growth stage, keep the soil dry and refreshing to encourage the roots to grow deep and lateral roots to multiply. There should be no standing water in the field; drain it in time to avoid root rot from too much water. Then when fertilizing, mainly use farmyard manure and compound fertilizer. After the seeds germinate, apply an appropriate amount of dilute human waste. When the broad bean seedlings have grown about 5 leaves and are about 6cm tall, apply a top dressing. Then apply top dressing again at the bud stage and pod stage to meet the nutritional needs of broad beans.
