Planting time and method of black adzuki bean

Planting time: adzuki bean is usually planted in the middle of may, and the maturity period is about 70 days. Planting method: select high-quality varieties, adopt trenching sowing method for planting, apply proper amount of soil fertilizer, diammonium phosphate and potassium sulfate as base fertilizer, thin seedlings when black adzuki bean grows two true leaves, apply proper amount of soil fertilizer in later stage, and use methyl isofenoxal, diethoate and other pesticides to control diseases and insect pests.

1. Black bean planting time

The planting time of adzuki bean is mid-May, and the maturity period of adzuki bean is generally more than two months, about 70 days.

II. Cultivation methods of black beans

1. Select improved varieties

Can choose big sheep eye black adzuki bean to carry on planting, this breed thousand grain weight is high, resistant disease and insect pest, can choose to rush stubble after wheat harvest sowing.

2. Appropriate planting period

Black adzuki bean can be planted by ditching and sowing method. Generally, 2 meters is a planting belt, which can be planted in 6 rows. The suitable row spacing is 30cm, the suitable plant spacing is 12.5 cm, the seed amount is 4-5 kg per 1/15 hectare, and 17,000 seedlings can be reserved.

3. Formula fertilization

Due to the large consumption of soil nutrients by the previous crop wheat, it is necessary to increase the basal fertilizer appropriately. Generally, every 1/15 hectare, 2500 kg of soil fertilizer, 15 kg of diammonium phosphate and 10 kg of potassium sulfate can be applied. During this period, deep application can be carried out in combination with trenching and loosening.

4. Field management

When black adzuki bean grows two true leaves, it is necessary to thin seedlings in time, during which impurities can be removed and inferior seedlings can be removed. When seedlings grow neatly, they should be tilled and stubble cleaned in time, and 2000 kg of soil and miscellaneous fertilizer should be applied. The flowering period should be watered properly.

5. Prevention and control of pests and diseases

Generally, 50% isofenoxal methyl 50ml can be used every 1/15 hectare, and then 50- 70kg of water can be added for control. In the middle and late stages, aphids, bridge-making insects, pod borers and bean moths can be mainly controlled. 25% dichlorid 1500 - 2000 times solution or omethoate 1500-2000 times solution can be used for spray control.

6. Timely harvest

When harvesting adzuki beans, the beans can be picked by stages. Under the premise of not affecting autumn sowing, the harvesting time can be appropriately extended, which is conducive to promoting post-ripening and improving yield.

Third, what is the difference between black beans and black beans

1. Different taste

The taste of black beans is similar to soybeans, so it needs to be stewed for a long time. The stewed black beans taste more powdery and are more suitable for children and the elderly.
