What are the precautions for growing black beans? A detailed explanation of the latest key growing points

Black beans are a black variety of soybean, with a protein content of 36%, and they are easy to digest, making them one of the main foods for supplementing the human body's protein. Black beans are also very rich in trace elements, and they have very good effects on regulating bodily functions and supplying the trace elements needed by the brain. So today let me introduce the precautions for growing black beans.

1. Choosing varieties

The quality of the black bean variety directly affects the yield and quality of black beans. Some studies have found that if black beans are not purified, after two to three years the beans will become smaller. Therefore, when choosing seeds, you should select plump seeds of roughly similar size for planting, so as to increase the yield.

2. Sunning and treating seeds

On a sunny day, spread the seeds evenly on flat ground and turn them to dry evenly for about two days to increase the germination rate. After the seeds have been sunned and treated, for each kilogram of seeds, mix evenly with a 0.1% zinc sulfate dilution, a 0.5% borax dilution, and a 2% ammonium molybdate dilution.

3. Land preparation and fertilizing

If crops were previously grown on the land where black beans are to be planted, the land should be plowed once, with a plowing depth of about 0.2 m. After plowing, the soil should be tamped firm to maintain good drainage between the soil, and the plot should be made into a structure that is loose on top and firm below. Before cultivation, apply 2500 kg of farmyard manure per mu to supplement fertilizer.

4. Sowing

Sowing generally begins after late spring, depending on the situation. Dig the land into rows of trenches. When sowing, bury the beans with the eye facing the soil, with the condition that the bean seeds cannot be seen, and after covering with soil, press the soil firm. If mixed planting is used, hole sowing can be adopted, with two to three seeds per hole, and about 3 kg of seeds needed per mu.

5. Field management

After the seeds emerge, immediately check the emergence situation, and if there is a shortage of seedlings, replant at once. From the emergence stage to the flowering stage, weed at least 3 times, then apply urea as a top dressing. If drought occurs, irrigate promptly to replenish water for the black beans, and in the rainy season drain the water promptly. When the seedlings grow taller than 30 cm, remember to pinch off the growing tips to slow the growth at the top and control their horizontal development.

6. Disease control

Although black beans have strong disease resistance and there are not many pests and diseases that can harm them, some diseases can still occur if management is improper. For example, viral diseases, aphids, and so on. Pay close attention to the condition of the stems and leaves of the seedlings, and treat according to the symptoms based on changes in the stems and leaves.

The above are the precautions to note when growing black beans. Although the points to note for each crop are similar, the environments suitable for each crop are different. Like black beans, when selecting seeds in the early stage, be sure not to choose small, shriveled seeds, as this has a great impact on yield and quality.
