Soilless cultivation of pea sprouts
First, the choice of species. Use varieties with high germination rate, strong disease resistance, no pods, high yield, low fiber content, and good quality, such as small peas, hemp peas, and long bean peas. Second, soaking. After drying and cleaning the seeds, the seeds are first washed with clean water for 2 to 3 times, washed clean and soaked in warm water at 55° C. for about 15 minutes, and soaked in warm water for 6 to 8 hours. Third, sowing. Clean the seedling tray in advance and spread the substrate. The size of the seedling tray is 60 cm, 25 cm, and 5 cm. It is advisable to use sterile pearls, fine sand, and non-woven fabrics. First spread a layer of substrate and then spread the soaked seeds evenly and levelly. The seeding rate is 450 to 500 grams per plate. Then spread a thin layer of substrate, cover the seeds, and then spray the warm water at 20°C. The dish is placed on a nursery stand, where each pot is placed at a height of about 10 plates. The top dish is covered with a light-shielding insulation material such as a wet cloth. Fourth, the seedlings after the shelf management. After the seedlings are put on shelves, they are covered with a clean black plastic film or cultured in a dark room to promote the growth of buds in the dark. Every 4 to 6 hours, the plastic film was sprayed with water at 20°C for one time. When the water was sprayed, germination was checked at the same time to eliminate the rotten spoilage seeds. Seedling height can reach 15 to 16 centimeters from 8 to 10 days. The cotyledon has just started. The shade should be removed immediately when it is used. It can gradually adapt to strong light conditions. The shade can be completely removed after two days so that the buds will be exposed to natural light. Continue to grow, so that buds turn from yellow to green. Generally after 12 to 15 days of cultivation, timely harvesting can be conducted according to market demand. The entire plate can be sold or neatly coded for sale in a plastic box plastic bag.
