What precautions are there for growing black soybeans? Key points explained in detail

Black soybean is the black-seeded form of soybean. Its protein content reaches 36%, and it is easy to digest, making it one of the main foods for supplementing human protein. Black soybeans are also very rich in trace elements, and have very good effects on regulating human body functions and supplying the trace elements needed by the brain. So today I will introduce to you the precautions for growing black soybeans

1. Choosing varieties

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

2. Sunning and seed dressing

On a sunny day, spread the seeds evenly on flat ground and turn them evenly to sun them for about two days to increase the germination rate of the seeds. After the seeds are sunned and processed, for each kilogram of seeds, use a 0.1% zinc sulfate diluted solution, a 0.5% borax diluted solution, and a 2% ammonium molybdate diluted solution, and stir them evenly.

3. Land preparation and fertilization

If the land for growing black soybeans has previously grown crops, the land should be plowed once, with a plowing depth of about 0.2 m. After plowing, the soil should be tamped down to keep good drainage between the soil, and the plot should be formed 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

Generally, sowing begins after late spring, depending on the situation. Dig the land into furrows arranged in rows. When sowing, bury the beans with the eye side 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. If there is a shortage of seedlings, replant immediately. From the emergence stage to the flowering stage, weed at least 3 times, then apply urea as a top dressing. If drought occurs, irrigate in time to replenish water for the black soybeans, and in the rainy season drain the water in time. 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 soybeans 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 prescribe the right treatment according to the changes in the stems and leaves.

The above are the precautions to note when growing black soybeans. Although the points to note for each crop are roughly similar, the environment suitable for each crop is different. Like black soybeans, when choosing seeds in the early stage, you must be careful not to choose small, shriveled seeds, as this has a great impact on yield and quality.
