Broad beans can be harvested after growing for about 200 days. The growth of broad beans generally needs to go through germination seedling stage, seedling stage, bud branching stage and flowering and pod setting stage. Selecting seeds with full seeds and excellent varieties for planting, soaking the seeds in warm water for 2-3 days to absorb enough water; Broad beans can be sown when planted in the open field, and seedlings can be checked in time to fill gaps, loosen soil and weed after emergence; When it grows to 3-4 leaves, it needs topdressing.

1. How many days can broad beans be harvested during the growing period?

1, broad beans can be harvested in about 200 days. Broad beans generally need to go through four stages: germination stage, seedling stage, budding and branching stage and flowering and pod setting stage. Because of different varieties and growing environments, the growth period is also different.

2. When planting broad beans, select seeds with full seeds and excellent varieties for planting, soak the seeds in warm water for 2-3 days to let them absorb enough water, and add potassium permanganate solution to the water to reduce the incidence of broad beans.

When the broad bean seeds turn white, you can sow. After emergence, check the seedlings in time to fill in the gaps, loosen the soil and weed to avoid broad beans lodging. The broad bean should be pitted when it bears the first pod, and the redundant side branches and long branches of the plant should be pruned during the later maintenance.

4. When the broad bean plant grows to 3-4 leaves, it needs topdressing, and potassium sulfate and decomposed organic fertilizer can be used, so that the broad bean can grow vigorously. When broad beans bloom and bear pods, foliar fertilizer should be sprayed on the leaves of broad beans to increase the number of broad beans bearing pods.

Second, when is the broad bean generally suitable for planting?

1. Sow broad beans in northwest China from early March to mid-April, and sow in southern autumn broad bean area1mid-October. In the production of dry broad beans, attention should be paid to avoiding sowing in early autumn, and it is generally more appropriate to finish sowing at the first dawn of110 to avoid the harm of low temperature frost at flowering stage to broad beans.

2. Broad beans are best planted on sandy soil with fertile soil, good drainage and rich organic matter, and the soil pH should be moderate, but broad beans can also be planted in alkaline soil. It should be noted that the previous crop of planting land cannot be melons and beans, and continuous cropping cannot be carried out on the same land, which will affect the growth of broad beans

3. Broad beans have strict requirements on temperature, because they are neither cold nor heat-resistant. The suitable temperature for broad bean growth is about 20-25℃, and the suitable temperature for broad bean germination is about 16- 18℃. Therefore, it is necessary to plant broad beans in strict accordance with their living habits, so as to grow better and increase yield.

4. It is also a wet-loving plant, but it is not tolerant to waterlogging, so it requires high water management in the field. When water is needed, it needs a lot of watering, when the soil is soaked, it needs to be drained in time, and when it encounters heavy rainfall, it needs to be drained in time. The growth of broad beans still needs a lot of nutrients, but the application of nitrogen fertilizer cannot be biased, which will lead to the phenomenon that broad beans only grow branches and leaves without pods.
