Choose a place with deep soil and good drainage as the planting site, before planting, the soil should be turned over once, and then start to make the bed, after doing a good job in the bed into the appropriate amount of manure and calcium superphosphate; soak the seeds for a period of time, and then put them in the environment of 25-28 ° C to promote the germination of the seeds, after 1-2 days after the seeds are sown into the bed; the seeds after the emergence of seedlings should be transplanted in a timely manner, and after transplanting, timely check the seedlings and replenish seedlings. The seeds should be transplanted in a timely manner, and the seedlings should be checked and replenished in a timely manner after transplanting.
A, land preparation
1, choose a deep, fertile, well-drained soil as a planting site, and then turn the soil over once, after the soil is sun white began to do beds, the height of the bed to 30 cm or so, the width of 1.5 meters or so appropriate.
2, in the borders of the furrow fertilization, generally can mu 1500-2000 kg livestock manure, 20 kg calcium superphosphate.
Second, soak the seeds
1, soak the bean seeds in 50-55?C warm water for 15-30 minutes, during which time it should be constantly stirred, and wait until the temperature of the water is reduced to 30 ° C and then soaked in water for another 3 hours or so.
2. Fish out the seeds and wash the mucus on their surface, then wrap them in clean, wet gauze and place them in an environment with a temperature of 25-28?C to germinate, and then start sowing after 1-2 days.
3, sowing
1, the plot of watering, and then in the way of open-air broadcasting the seeds into the soil, sowing the seeds should be placed flat in the soil pit (each pit can generally put 2 seeds), and then cover the soil.
2. The plant spacing for spring sowing is usually 15-20 cm, and the plant spacing for spring sowing is usually 12-20 cm, and the mu seed amount is about 1-1.5 kg.
Four, transplanting
When the seed and seedling height of about 10 centimeters (the first pair of true leaves just unfolded) can be transplanted, transplanting should be watered with the right amount of water, after 5-7 days in a timely manner to check the seedling, replenish the seedling.
