Key points of broad bean cultivation How to grow broad beans

What issues and matters should we pay attention to when cultivating broad beans? Today we will introduce them to you:

(1) Choose the right crop rotation and plot:

Broad beans should not be planted continuously. Continuous planting will make the plants sterile. The number of rhizobia is small, the activity is low, the pods are few, and they are prone to disease. When planting broad beans, crop rotation should be implemented for at least 3 years. Broad beans are adapted to slightly heavy and moist soil, but it is better to plant them in deep, fertile clay loam or sandy loam.

(2) Sowing at the right time:

Broad beans are cold-resistant and can be sown from late February to mid-March. Before sowing, deep plow the soil and apply appropriate basal fertilizer to make a flat bed 1 meter wide. Plant two rows in each bed, dig holes in the bed, the hole depth is 6-9 cm, the hole distance is about 20 cm, sow 2-3 seeds in each hole, and level the bed surface.

(3) Top dressing and watering:

Adequate water supply should be provided 1-2 days after sowing to promote early germination and early uniform seedlings. When the seedlings grow to 3-4 true leaves, an appropriate amount of nitrogen fertilizer should be applied, and phosphorus and potassium fertilizers should be applied in stages during the growth period. Spraying potassium dihydrogen phosphate or trace elements such as boron, molybdenum, magnesium, and copper during the flowering and pod-setting period can reduce flower and pod drop, promote seed development, and increase yield. In the early stage of broad bean growth, inter-cultivation is the main method to increase soil water retention and permeability. The soil should be kept moist from the beginning of budding and flowering. Lack of water during the flowering and pod-setting period can easily cause flower and pod drop, and the beans will not be full.

(4) Cultivation and pruning:

After the broad bean seedlings emerge, the seedlings should be checked and the gaps should be filled in time. During the seedling stage, multiple intertillage and weeding should be carried out, and the soil should be raised to the roots of the plants to prevent lodging. Broad beans have a strong branching ability, and the branches and pods in the later stage are few and easy to cause field closure. In production, the excess side branches should be broken off and the growth points should be removed in time to reduce nutrient consumption, increase the pod setting rate, and promote full beans and uniform maturity.

(5) Harvest at the right time:

The young pods of broad beans can be harvested in batches, from bottom to top, once every 7-8 days. The mature seeds can be harvested when the leaves fall and the middle and lower pods are fully mature, and then dried, threshed and stored.
