Pea seedlings alias pea tip. The tender shoots of peas are rich in nutrients, soft and sweet. Pea seedlings are green and leafy, with thick leaves, few fibers, and tender shoots. They are treasures in winter and spring vegetables. They are green vegetables with high nutritional values ​​and are pollution-free health-care vegetables. They have a promising future. The pea seedling planting is introduced as follows: Pea seedlings can be cultivated in spring, autumn and winter, and planted in spring from March to April and harvested from May to June. Commonly there are common Shanghai pea seedlings, Shangnong without pea seedlings, and Sichuan without bean tips. No. 1 and so on, of which the fastest harvest can be Sichuan without peas, half sprawl, 20 days after sowing can be harvested, even received 9-10 times, each time 1000 kg per mu. The output of pea seedlings mainly depends on the seedling number, with 13-15 kilograms of seeds per acre, 1500 kilograms of manure fertilizer before planting, 100 kilograms of plant ash, and 25 kilograms of superphosphate. After intensive cultivation, it is finished into a 1.3-meter-wide bunting, which is broadcast by 10-15 centimeters of space, and covers 1-2 centimeters after sowing. Qi seedlings were planted 7 days in early spring, and 1-2 cm of cover soil was applied 1-2 times after emergence. During the seedling stage, we must top-dress fertilizer and water in order to keep the soil dry and wet, and weeding before closing the line. When about 2 true leaves are to be treated in time, nitrogen fertilizer can be applied in a timely manner. Each time the dressing is applied one time, 4 kg of urea is diluted with water to 0.3%, and applied for 4-5 times, and 0.2% potassium dihydrogen phosphate is topdressed. During the period, it mainly controlled yellow tip disease, powdery mildew, aphids, and leaf miners that harmed the leaves. 20-30 days after sowing, seedlings grow 8-9 cm in time for a one-time harvest, through the planing root, bundle handle, removal of stem base root, washed after listing. For multiple harvests, when shoots are 15-20 centimeters tall and 7-8 true leaves are picked, young shoots are picked. When the stipules are not opened, the young shoots of the upper compound leaf are harvested, together with 1-2 unexpanded young leaves, harvested once every 7-10 days, each time can receive 1000-1500 kg, net income per mu can be achieved. Ten thousand yuan.
