A Detailed Guide to Adzuki Bean Seed Selection and Seedling Raising Methods

It is said that what botany calls hongdou (red beans) includes three kinds: adzuki bean, sea bean (Adenanthera pavonina) and love pea (Abrus precatorius). These are three types of plants in the same family but different genera. Below, let us learn about the differences between adzuki beans and red beans, as well as the seedling raising methods for adzuki beans.

1. How to select adzuki beans? What is the difference between adzuki beans and red beans?

1. Different effects

Adzuki beans contain vitamin B2, niacin, calcium, iron and other nutrients, and have the function of reducing fat and aiding weight loss. Red beans have the functions of clearing heat and detoxifying, strengthening the spleen and benefiting the stomach, promoting urination and reducing swelling, and relieving qi stagnation and irritability; they can treat conditions such as difficult urination, edema due to spleen deficiency, and athlete's foot.

2. Different appearance

Adzuki beans are slender and slightly flat. After cooking, red beans will become soft, but adzuki beans, even after being soaked and then cooked, still cannot be cooked soft and taste rather hard.

2. Adzuki bean seedling raising methods

1. Land preparation and making beds

Adzuki beans cannot be planted in continuous cropping, so the previous crop in the planting site cannot be a legume crop. It is best to use farmland that has previously grown crops such as wheat, corn or sorghum. The soil fertility of the planting site does not need to be too high, the drainage system must be well developed, and at the same time it must be conducive to irrigation; most importantly, there must be sufficient sunlight. Leguminous plants all have very vigorous vitality. When preparing the land, it is still necessary to clean up debris in the field, which can reduce the harm of pests and diseases. Next, level the ground, dig water furrows, make the beds properly, and then you can wait to sow.

2. Sowing methods

Adzuki beans are generally sown by drilling or hole sowing. For drilling, the distance between each row is generally about 35 cm, and then seeds are evenly scattered at intervals of 25 cm, then covered with soil to bury the seeds. For hole sowing, holes are opened at intervals of 30 cm, then 4 to 5 seeds are sown into each hole, and finally the soil is covered to bury the seeds and wait for emergence.

3. Field management

After sowing, weeds in the field need to be removed. Generally, sethoxydim can be mixed with water and sprayed on the weeds in the field. At this time, the weeds are generally about 10 cm; otherwise, they cannot be completely removed, and manual weeding will still be needed later. In order to prevent adzuki beans from lodging and to promote the rapid growth of adzuki bean seedlings, we need to carry out at least three rounds of intertillage and hilling. During the growth period of adzuki beans, the water requirement is relatively large, so we should irrigate reasonably to avoid affecting yield and quality. Finally, we should apply topdressing scientifically and must not apply nitrogen fertilizer in a one-sided way. In the early stage, apply a small amount of nitrogen fertilizer to promote seedling growth; in the later stage, apply potassium fertilizer, phosphate fertilizer, boron fertilizer and the like. In order to avoid excessive vegetative growth of the plants, we also need to spray paclobutrazol to inhibit growth and increase the pod-setting rate.

4. Pest and disease control

The most common diseases of adzuki beans include rust disease, brown spot disease, dwarf disease and lodging disease. We can use mancozeb solution and carbendazim respectively for control, and at the same time enhance the immunity of the plants through chemical regulation methods. The main insect pests of adzuki beans are aphids and red spider mites, which can be killed respectively with imidacloprid water-dispersible granules and Zhongbao acaricide emulsifiable concentrate.
