Is North China suitable for growing broad beans (when and how to grow broad beans in North China)

Is North China suitable for growing broad beans?

Broad beans have a very long history of cultivation in my country, so the planting area is also relatively large. Except for Northeast China and Hainan, broad beans can be grown in most other provinces.

The areas south of the Yangtze River mainly sow in autumn and plant in winter, while the areas north of the Yangtze River usually sow in early spring and harvest in autumn. Therefore, broad beans can be grown in North China .

How to get high yield of broad bean in North China

First, choose high-quality varieties.

Before sowing, the land should be deeply dug and plowed to make the land loose, which is conducive to root expansion, germination and formation of nodules. Inoculation of rhizobia can then increase yield.

We can use the soil inoculation method to take about 100 kilograms of soil from the soil where broad beans have been planted, and sprinkle it in the ditch when sowing.

In terms of planting time, North China generally sows from mid-to-late March to mid-to-late April, which is spring plowing, and harvests in early autumn .

Most coastal areas sow between October and early November, which is autumn sowing, and harvest in the autumn and winter of the following year .

However, broad beans cannot be planted in succession. You should choose land that has not been planted with lentil or other legume crops for more than 2 years, and the previous crop should be corn, cereals, or vegetables.

Secondly, pay attention to seedling management.

After sowing, cover with soil and straw to maintain temperature and humidity. In the middle of growth period, pests and diseases should be prevented and treated, diseased plants should be treated, diseased remains and weeds should be removed and destroyed.

Spray pesticides to prevent pests and diseases, control water, and tidy up branches and seedlings. To ensure the normal development of plants. In the later stage, ensure the plant's demand for water, control the density, and maintain good ventilation and light transmission between the fields.

Third, do a good job of fertilization and irrigation.

When broad beans grow young leaves, you can apply some nitrogen fertilizer in small amounts. During the growth period, you should apply phosphorus fertilizer and potassium fertilizer at different times.

When the pods are formed, more trace elements should be applied to reduce the phenomenon of flower and pod drop and achieve high yield. In the early stage, it is mainly necessary to ensure drainage and ventilation, otherwise it will cause the flower and pod to fall and the beans to shrivel.

Fourth, pay attention to inter-row cultivation and pruning.

Check in time after the seedlings emerge, and replant immediately if any seedlings are missing. During the seedling stage, cultivate and weed frequently, compact the soil and prevent lodging.

Pay more attention to the branching of the seedlings before and after the flowering period. It is difficult for broad beans to form pods due to branching, so the excess branches should be removed to allow the main trunk to absorb more nutrients, increase the fruiting rate, and increase the fullness rate.

Finally, harvest at the right time.

When harvesting broad beans, you can do it in batches, from bottom to top, about once a week. You can save some mature seeds, pick the pods in the middle and lower parts when the leaves fall, and then peel the pods after drying to save the broad beans.
