When to Plant Broad Beans? Detailed Guide to Planting Time and Methods
SummaryBroad bean planting time: plant in spring from mid-to-late March to early April, and in autumn from early October to early November. Broad bean planting methods: select high-quality seeds, plow the soil before sowing, water promptly after sowing, then cover the seeds with soil and cover with straw to retain moisture; any standing water must be drained promptly; during the growing period, appropriately apply additional nitrogen fertilizer, phosphorus fertilizer, potassium fertilizer, etc.; in the later stage, prune excess branches and carry out pest and disease control promptly.
I. Broad Bean Planting Time
Broad beans are generally planted in spring or autumn; spring is from mid-to-late March to early April, and autumn is from early October to early November. Planting at the right time helps ensure uniform, even, and strong seedlings. Dry-grain broad beans should not be planted in early autumn, to prevent the broad beans from suffering low-temperature freeze damage during the flowering period.
II. Broad Bean Planting Methods
1. Seed selection and sowing
Select plump, high-yielding, disease-free high-quality seeds. Before sowing, plow the land to make the soil loose, which helps the roots and stems expand, sprout, and form root nodules. Then use rhizobium inoculation to increase yield. The soil inoculation method can be used: in a plot where broad beans have been grown, dig about 50 kg of soil and scatter it into the furrows during sowing.
2. Seedling stage management
(1) During the seedling stage, carefully observe the seedling conditions and apply corresponding control methods according to the seedling conditions. After sowing, cover the seeds with soil and cover with straw to keep them warm. In the mid-growth stage, pest and disease control must be done well; remove diseased plants and weeds and destroy them in a concentrated way by fire.
(2) Pesticides must be sprayed promptly for pest and disease control, moisture must be well controlled, and the branches and seedlings in the garden plot must be tidied to ensure normal growth and development of the plants. In the late growth stage, there must be a sufficient water supply, and the density must be reasonably controlled, which helps maintain ventilation and light transmission between plants.
3. Topdressing and watering
(1) After sowing, water promptly to help promote early seedling development, and gently compact the soil to avoid lodging of the plants after they grow larger. When young leaves grow, a small amount of nitrogen fertilizer can be appropriately applied as topdressing. During the growth process, phosphorus fertilizer and potassium fertilizer must be applied regularly as topdressing.
(2) During the pod-setting stage, more trace elements can be applied, which can reduce flower and pod drop in the plants and improve their quality and yield. In the early growth stage, the ventilation of the garden plot must be ensured, and when standing water appears, it must be drained promptly, which helps reduce the occurrence of flower and pod drop and shriveled beans.
4. Intertillage and pruning
After emergence, if missing seedlings are found, reseed promptly. During the seedling stage, frequently carry out intertillage and weeding, and press the soil firm and thick to avoid lodging. Around the flowering period, pay attention to the branching of the seedlings. If broad beans branch, it becomes relatively difficult for them to set pods, so excess branches must be pruned promptly to encourage the main stem to absorb more nutrients and improve its pod-setting rate and plumpness rate.
5. Timely harvesting
Broad beans can be harvested in batches, about once every 7 days from bottom to top. During this period, a small amount of mature seeds can be saved. When the leaves fall, pick the pods in the middle and lower parts, dry them in the sun, remove the shells, and store them.
