Detailed Explanation of the Planting Methods and Cultivation Techniques of Adzuki Beans
Adzuki bean, commonly known as red rice bean, is an annual herbaceous plant of the Vigna genus. Many people always confuse adzuki beans with red beans because they are very similar in appearance, and their effects and functions are also largely the same as those of red beans. It is a plant used both as medicine and food, and is cultivated in all parts of our country. So, is there any difference between the planting methods of adzuki beans and red beans? And how is it planted? Let us understand specifically below.
1. Land preparation and bed making
Adzuki beans cannot be grown continuously on the same land, so the previous crop in the planting site cannot be a leguminous 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 rich, the drainage system must be complete, and it must also be favorable for irrigation; most importantly, there must be sufficient sunlight. Leguminous plants have very vigorous vitality, and during land preparation it is still necessary to clean up debris in the field, which can reduce the harm of pests and diseases. Next, level the ground, make water ditches, prepare the beds, and then you can wait for sowing.
2. Sowing methods
The sowing time of adzuki beans is greatly related to the climate of the planting site, but when planting adzuki beans in our country, sowing can generally be carried out from early April to May. The sowing methods for adzuki beans generally use 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, covered with soil, and buried for sowing. For hole sowing, holes are opened at intervals of 30 cm, then 4 to 5 seeds are scattered into each hole, and finally soil is covered to bury the seeds and wait for seedlings to emerge.
3. Field management
After sowing, we need to remove weeds in the field. 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 removed thoroughly, and manual weeding will still be needed later. In order to avoid lodging of adzuki beans and promote the rapid growth of adzuki bean seedlings, we need to carry out at least three rounds of intertillage and earthing up. 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, and in the later stage, apply potassium fertilizer, phosphorus 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 are rust disease, brown spot disease, atrophy 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 spiders, which can be killed respectively with imidacloprid water-dispersible granules and Zhongbao acaricide emulsifiable concentrate.
The above are the planting methods for adzuki beans. I believe everyone now has a certain understanding of adzuki bean planting. That is all for today's sharing by the editor. If you still have other questions, you can consult the editor.
