How do you select hyacinth bean seeds? What are the seedling-raising methods?

Hyacinth bean, also called black-eyed pea, has high nutritional value, is a very popular vegetable on the autumn dining table, and also has the medicinal value of strengthening the spleen and draining dampness. As the hyacinth bean becomes more and more popular on the market, it has also attracted many farmers to grow it. So how do you select hyacinth bean seeds? What are the seedling-raising methods? Let's take a look together below.

1. How do you select hyacinth bean seeds?

Select hyacinth bean varieties suitable for local planting. There are many hyacinth bean varieties, and you can choose a suitable hyacinth bean variety according to the different planting seasons. It should meet the requirements of cold tolerance, heat tolerance, high yield, early maturity, strong stress resistance, early and abundant pod setting, good commercial traits, and excellent quality. Choose seeds of good quality that are plump and free of mold.

Before planting hyacinth beans, seed soaking and germination promotion treatment should be carried out, especially for hyacinth beans planted as a spring crop. Since the air temperature is not high and the temperature has not reached a certain value, this has a certain delaying effect on hyacinth bean germination, and adopting the soaking method can effectively play a role in allowing the seeds to germinate quickly. Place the seeds in clean water and soak for two days, or wrap them with a wet towel, and once the seeds show white, they can be planted. For summer sowing, because the air temperature is very high, under normal circumstances, direct dibbling is enough for germination and growth.

2. What are the seedling-raising methods for hyacinth beans?

1. Planting time

Hyacinth beans are generally cultivated in the open field in summer, and usually after mid-January can be successively guaranteed, but the climate in different regions is different, so its sowing time is also different. For example, in the Yangtze River Basin, the planting time for hyacinth beans is from May to July, while in North China the planting time is mostly in June.

2. Seed selection and seedling raising

Hyacinth beans can be divided by pod color into white hyacinth bean, green hyacinth bean, and purple hyacinth bean. Among them, the green hyacinth bean pod is flat and thin, crisp and tender; the purple hyacinth bean is similar to the white hyacinth bean, with thick pod flesh, and is soft when cooked. 

When sowing, combined with plowing, apply 3000 kg of decomposed farmyard manure per mu and an appropriate amount of chemical fertilizer as base fertilizer. The fertilizer should be mixed evenly with the soil, then harrow and level the land. Hyacinth beans are generally mostly direct-sown, using the method of furrow sowing or hole sowing, with plant spacing controlled at 35-50 cm and row spacing at 100-130 cm. Generally, sow 3-4 seeds per hole, and after emergence keep two seedlings per hole.

3. Field management

Hyacinth beans have strong drought tolerance. The seedling stage needs water for watering, and the vine extension stage and pod setting stage need water for watering. Generally, in the vine extension stage, watering is needed 1-2 times, and in the flower and pod stage, water once every 10 days. After watering, timely carry out intertillage and weeding, and at the same time combine with topdressing to prevent flower and pod drop or excessive vegetative growth. Fertilization before flowering should be applied lightly and thinly, and fertilization after flowering during the pod setting stage should be applied heavily.

Intertillage should be shallow; one year of root injury, when fertilizing, attention should be paid to the reasonable combination of nitrogen, phosphorus, and potassium, and attention should be paid to the application amount of nitrogen fertilizer. Before vine drawing, trellises can be set up, or after vine drawing, use ropes in time to guide the vines onto the trellis. When guiding the vines, make the stems and vines evenly distributed on the trellis. When the main vine grows to 1.5 m, pruning and pinching can be carried out to promote the development of more side branches and vines on the side branches, and to advance flowering and pod setting.

The above is the introduction to hyacinth beans. Hyacinth beans are actually a plant that is quite easy to grow. This extensive type of climbing plant is deeply welcomed by farmers because it is easy to manage and bears many fruits.
