2. Pea seedlings generally refer to pea seedlings, small pea seedlings with seeds themselves, including planting methods of picking pea stems and leaves repeatedly. It can be cultivated without soil or in the open field. The first pea seedling can be harvested 20 days after sowing, and then harvested every 3-5 days. The maximum harvest is 9- 10 times, and the yield per mu is 1000- 1500 kg.
3. Planting time. The suitable temperature for indoor cultivation is 20℃, and the suitable time for outdoor cultivation is selected according to the natural conditions in various places. The northern region can be planted all the time as long as the temperature is suitable from March, and the southern region can be planted all year round. But most of them are planted in September-165438+10 in autumn, and the temperature conditions are suitable and easy to manage.
4. Seed soaking treatment. Soak the seeds in warm water before sowing, and start sowing after swelling, which can be seedling tray or open field cultivation.
5. Plant pea seedlings on the seedling tray. Disinfect with bactericide such as Junjunqing, spray water 1-2 times a day, and change the position of seedling tray, and then carry out routine management when pea seedlings grow to 2-3 cm. There should be some light every day, but not too strong, avoid too much cellulose, pay attention to ventilation and water spraying, and adjust the temperature to avoid rotten seedlings. Collect once every 3-5 days and once every 2-3 times.
6. Cultivate pea seedlings in the open space. Before sowing, apply 65,438+0,500 kg of decomposed farmyard manure, 65,438+000 kg of plant ash and 25 kg of calcium superphosphate, and then cultivate in a flat bed. Each mu needs seeds 13- 15 kg, cover soil 1-2 cm, and keep the soil dry and wet after emergence. Spraying 0.3% urea solution on two real leaves, spraying 0.3% urea solution and 0.2% potassium dihydrogen phosphate after picking.
7. harvest. If it is a one-time harvest, it is usually carried out when the seedling height is 8-9 cm. Usually it is harvested many times. When the seedlings grow to 15-20cm or 7-8 true leaves, pick the upper shoots.
