"King of beans" black bean planting technology is explained in detail!

Black beans are the black seeds of leguminous plant soybeans. Black beans are high in protein and easy to digest. They are rich in vitamins, vitellin, melanin and lecithin. Black beans are also rich in trace elements. The following is a detailed explanation of the planting techniques of black beans, the king of beans!

I. seed selection and treatment

The quality of seeds determines the yield and quality, so it is very important to select varieties with strong growth, strong disease resistance and stable yield, and to remove diseased grains, insect seeds and mildew grains. Large seeds with spherical and oval shape and light white powder are selected for sowing. Before sowing, the seeds should be treated to improve the germination rate. When the weather is clear, spread the seeds on the ground and turn them over for 1-2 days. Sunning seeds and then mixing with zinc sulfate and borax diluent to eliminate the bacteria on the surface, you can sow seeds.

II. Soil preparation and fertilization

Select the flat land that requires loose soil and good drainage for planting, turn deeply 15-20cm before planting, rake the soil fine and flat after turning, and require fine broken soil without obvious soil and stone. Fertilize the land after sowing, apply farm manure 2000-3000kg per mu, or use organic fertilizer 400kg, with phosphate and potash fertilizer and other fertilizers. Farm manure is applied before soil preparation. And organic fertilizer and other fertilizers are applied when turning the soil.

3. Sowing and raising seedlings

Black beans can generally be sowed when the soil temperature is 10 degrees Celsius. Generally, hole sowing and strip sowing can be used from March to April. If they are not planted in the same land as other crops, strip sowing is generally used. Strip sowing should pay attention to the neatness and consistency of the soil cover, prevent differences in depth, and pay attention to sowing density, not too thick, generally leaving about 10,000 plants per mu. Sow 3-4 seeds per hole, cover soil with 3-4cm, and use 2-3kg per mu. Pay attention to the situation in the field after sowing, check in time after emergence, and replenish seedlings in time when missing seedlings are found. When compound leaves are grown, interseedlings can be removed to remove diseased seedlings, weak seedlings, miscellaneous seedlings and so on.

IV. Field management

Field management includes intertillage weeding, fertilizer and water management, topping chemical control and pest control, etc. Black beans have to carry out 3-4 times of intertillage and weeding from seedling emergence to flowering, the first time at seedling emergence, the second time at interseedling, the third time at seedling height 10cm, after black bean enters the flowering stage, after various growth stages, the base fertilizer has been consumed almost, so it is necessary to maintain nutrient supply by topdressing. Generally speaking, after topdressing urea with 5kg per mu, foliar fertilizer spraying and root spraying fertilizer can be carried out according to the growth status, timely watering should be carried out in the dry period, and attention should be paid to drainage and waterlogging prevention measures in the rainy season.

In order to make the plant start to bear fruit and inhibit the plant growth to be too dense, timely coring is necessary, when 5-6 leaves grow, make it grow horizontally, and when it grows 4-5 branches, remove the terminal bud in time to promote the growth of branches. Black bean planting main diseases are mosaic virus disease, bacterial spot disease, pests are aphids, heart borer, it is necessary to do a good job in their control.

The above is the introduction of black bean planting technology by Tuliu.com. Black beans are planted everywhere in China from south to north, and the richness of variety resources is the first in the world. Most of them are distributed in the Yellow River basin and are the main producing areas of small black beans.
