Red adzuki beans, as a nutritious and highly medicinal bean crop, have a long history of cultivation in China. Knowing the best time to sow adzuki beans is essential to improve their yield and quality. This article will detail the planting season and the best time to sow red beans.
1. The planting season of red adzuki beans
Adzuki beans like a warm environment, the suitable temperature for growth is 15 30, when the temperature is lower than 5, it is easy to be damaged by frost, and above 30, it will affect its normal flowering and poding. Therefore, the growing season of adzuki beans is mainly concentrated in spring and summer, when the climate is mild.
Spring planting: Spring is one of the main planting seasons for adzuki beans. In March and April, when the temperature gradually warms up, the soil temperature gradually stabilizes in the range suitable for the growth of adzuki beans, and sowing at this time is conducive to promoting seed germination and seedling growth.
Summer planting: Summer-sown adzuki beans are mainly sown in areas with high temperatures from late spring to summer. The suitable time for sowing is usually in May to July. The adzuki beans sown at this time are able to grow normally in the hot and rainy summer climates and obtain high yields.
Second, the best time to sow red beans
1.Timely early sowing: In the spring planting season, timely early sowing is beneficial to prolong the growth cycle of adzuki beans and promote their full growth. Early-sown adzuki beans are better able to adapt to lower temperatures and avoid adverse climatic conditions such as high temperatures and droughts. Depending on the climatic characteristics of different regions, the timing of early sowing is usually from mid-March to early April.
2.Reasonable dense planting: Reasonable dense planting is one of the key measures to increase the yield of adzuki beans. During the appropriate sowing period, the appropriate sowing density should be determined according to factors such as soil fertility and irrigation conditions. As a rule, the sowing amount per mu is 4 5 kg and the sowing depth is 3 4 cm. Planting too closely can lead to poor ventilation and lack of light, while too thinning can affect yield per unit area.
3.Water management: Adzuki beans have a high water requirement, especially at the seedling and grain drum stages, where the soil needs to be kept moist. In arid areas or during the dry season, irrigation should be carried out in time to meet the water required for the growth of adzuki beans. At the same time, attention should be paid to drainage and waterlogging prevention in the rainy season to avoid root rot caused by soil waterlogging.
4.Fertilization management: Adzuki bean is a crop that needs more fertilizer, and should be reasonably fertilized to meet its growth needs. The base fertilizer is mainly organic fertilizer, and phosphorus and potassium fertilizer are appropriately addedTop dressing is mainly nitrogen fertilizer, which is mainly applied at the flowering and podding stages. The amount and frequency of top dressing should be based on soil fertility and plant growth.
5.Pest control: Common pests and diseases of adzuki bean include rust, aphids, spotted loon flies, etc. The prevention and control of pests and diseases should follow the principle of "prevention first, comprehensive control", strengthen field management, and remove diseased residues and insect eggs in a timely manner. When pests and diseases occur, low-toxicity and high-efficiency pesticides should be selected for prevention and control, and attention should be paid to the safety interval and use methods of pesticides.
6.Harvesting and storage: The harvest period of adzuki beans is generally around September, when the pods turn yellow and the kernels become hard. After harvesting, it should be dried, threshed, and impurities removed in time to maintain the purity of the seeds. After drying, the seeds should be stored in a ventilated and dry place to prevent moisture, insects and rodents, etc., to ensure the quality and safe storage of seeds.
In conclusion, the planting season of adzuki beans is mainly concentrated in spring and summer, and the best sowing time should be determined according to the local climate characteristics. Timely early sowing, reasonable dense planting, scientific water and fertilization management, and pest control are the key measures to improve the yield and quality of adzuki beans. In the process of harvesting and storage, the purity of seeds should be maintained, and measures such as moisture-proof and insect-proof should be taken to ensure the quality and safe storage of seeds. By understanding and mastering these planting techniques, growers can better grow adzuki beans and obtain better economic and social benefits.
