2. Planting methods of broad bean

1. Seed selection and sowing

The seeds of broad bean should be selected as local excellent varieties. The selected soil will be ploughed and ditched at the same time to open the soil moisture, the ditch and the ditch are connected, the ditch of the poorly drained field should be dug deep, and the soil moisture surface should not be too wide. After breaking the soil from the ditch, sow in the pond, and then cover the seed with fine dung or fine soil to ensure seedling emergence.

two。 Seedling stage management

In the seedling stage, the corresponding control methods should be made according to the situation of the seedling. After sowing, cover with soil and cover with straw to maintain temperature and humidity. In the middle of growth, it is necessary to do a good job in the prevention and control of diseases and insect pests, deal with the diseased plants, remove the disease and weeds and destroy them centrally. Spray pesticides to control diseases, pests and rats, control moisture, and arrange branches and seedlings. To ensure the normal development of the plant. In the later stage, the water demand of the plant should be ensured, the density should be controlled, and the ventilation and light between the fields should be maintained.

3. Fertilizer application

Base fertilizer can be applied before sowing, mainly farm manure. In the period of 3-4 leaves of broad bean, urea 2-3kg, calcium 10-20kg and potassium fertilizer 5-10kg per mu were mixed with three kinds of fertilizers and watered on the roots. Flowering and podding period is the peak period of broad bean life fertilizer, nitrogen fertilizer accounts for 80%, phosphorus 90%, potassium 63%. Generally, urea 3-5kg and potassium fertilizer 5kg are used per mu, and water is applied to the roots. In addition, potassium dihydrogen phosphate or molybdenum fertilizer can be used for foliar spraying to increase 100-grain weight.

4. Irrigation, pruning

Broad bean is a crop that needs more water, with few leaves and low temperature at seedling stage, and generally does not irrigate. There must be sufficient water in flower and pod stage, bud stage and seed filling stage, and timely irrigation of flower and pod water, bud appearance and seed filling water is the basis to ensure the normal growth of broad bean. When the main stem leaves grow to 3-4 bolting compound leaves, the top 1-2 bolting leaves of the main stem should be removed in time, and invalid branches and weak branches should be removed after the beginning of spring.

5. Ploughing and pruning

Check in time after emergence, and replant immediately if you find that there is a lack of seedlings. In the seedling stage, we should often plough and weed, pat and thicken the soil to prevent lodging. More attention should be paid to the branching of seedlings before and after flowering. Broad bean branches are difficult to bear pods, and extra branches should be removed to absorb more nutrients for the trunk, improve fruit rate and plumpness rate.

6. Timely harvest

When harvesting broad beans, it can be carried out in batches, from bottom to top, about once a week. Some mature seeds can be preserved. When the leaves fall, the pods in the middle and lower parts are picked, dried and peeled off to preserve the broad beans.

Whether we plant broad beans in autumn in the south or in spring in the north, we need to choose the planting environment according to the growth habits of broad beans.
