Planting method 1. Seed selection
Select the seeds with full grains, no pests, pick out moldy, damaged and shriveled seeds with high germination rate.
2. Seed soaking
Soak the seeds with 2~3% of the seed weight in water, soak the seeds for 10~16 hours in summer, and soak them in warm water at 65°C for 20~24 hours in winter.
3. Sowing
There is a layer of seedling paper in the seedling tray, and two seedling trays are covered with two layers of seedling paper to distribute the seeds evenly without leaving blanks or overlapping.
4. Germination
Stack 10 to 20 seedling trays on which the seeds are placed, and place two trays with two layers of seedling paper on each end. During the germination period, spray water 1~2 times a day. If you find rotten seeds, you should pick them out in time.
5. Management
When the seedlings are about 2 cm high, they can be put on the shelf. The temperature is high in summer, and the accumulated temperature generated by the seeds during the germination process is easy to cause rotten seeds. It can be put on the shelves earlier to reduce the rotten seeds. In winter, the temperature is low, and the accumulated temperature generated by the seeds during the germination process is conducive to growth. It can be put on the shelves later, as long as the seedlings are high Do not top the top plate.
Daily management: The suitable temperature for pea seedlings to grow is about 20°C. Under strong light, they can grow into large green leaf seedlings. Under no light conditions, they can grow into bright yellow dragon whisker seedlings. Under low light conditions, they can grow into tender green seedlings. . The relative humidity of the air is maintained at 70% to 80%. In addition, during the entire production process, attention should be paid to ventilation and dehumidification under the premise of ensuring the proper temperature for growth.
7. Harvest
When the seedlings grow to about 10 cm and the true leaves at the top have just unfolded, they can be harvested and cut from the root 2-3 cm.
