How to plant black bean sprouts How to plant black bean sprouts

Before planting black bean seedlings, the seeds must first be winnowed and rinsed in water to remove mechanically crushed, insect-eaten, moldy, and undersized seeds. When rinsing in water, the seeds must be gently rubbed repeatedly by hand, and impurities and inferior beans must be repeatedly skimmed off, and then the black beans must be sieved into a bamboo sieve to control the water.

Black bean seedling planting conditions

1. Moisture conditions

   Black bean seedlings require more water during the growth period, the least water is needed during the flowering and pod-setting period , and the water required during the pod swelling period is between the two .

2. Temperature conditions

   The planting temperature of black bean seedlings is very important. Black beans prefer warmth and need to be above 18 degrees to germinate , but it cannot exceed 25 degrees . The seedlings need to grow fast between 20-24 degrees .

Black bean seedling planting steps

1. Land preparation and fertilization

   When planting black bean seedlings, it is best to use agricultural machinery to deep plow the soil in the selected rice field to remove the roots and weeds left in the soil from the previous crop. Then apply 800 kilograms of organic fertilizer, 200 kilograms of urea, and 70 kilograms of calcium magnesium phosphate compound fertilizer per mu, and plow the soil again to turn the fertilizer into the ground.

2. Sowing time

   Black bean seedlings can be planted when the underground temperature rises to about 10 degrees in spring . Before sowing, wrap the seeds with seed coating to improve the immunity of the seedlings after germination.

3. Sowing method

   When sowing, first press the ridge board, then dig holes at a distance of 15 cm to 20 cm between each plant, and sow 3 to 4 black bean seedlings in each hole. After sowing, cover with 3 cm to 4 cm thick fine soil, press it lightly with a wooden board, and water it once.

Key points for high-yield management of black bean seedlings

1. Irrigation and drainage water management

   If you want the black bean seedlings to have a high yield, you must water them sufficiently when they enter the pod-forming stage , especially when there is continuous drought. If you do not water them in time, the fruits will easily fall.

2. Topdressing management

   When the black bean seedlings just enter the flowering period , 10-20 kg of urea should be applied per mu of field to promote the growth of black beans. After entering the peak flowering period , 80-90 kg of urea should be applied per mu of field to increase the number of pods.

3. Intertillage and weeding

   When the compound leaves of the black bean seedlings just grow out, shallow tillage should be carried out once , and all weeds in the field should be removed at the same time. When the black bean seedlings grow to 20 cm in height, intertillage and weeding should be carried out once, which can increase the yield of black beans at the time of harvest.
