Planting techniques of pea seedlings

Pea seedling alias pea tip, edible pea tender tip, rich nutrition, tender texture, sweet fragrance. Pea seedlings have green leaves, thick mesophyll, less fiber and tender shoots and leaves. they are the treasures of winter and spring vegetables and pollution-free health vegetables with high nutritional value. Here is an introduction to the cultivation of pea seedlings:

Pea seedlings can be cultivated in spring, autumn and winter, sown in March-April in spring, and harvested in May-June. Generally, there are pea seedlings in Shanghai, Shangnong needless pea seedlings, Sichuan Wuduojian No. 1, etc., of which the fastest harvest is pea-free and semi-trailing in Sichuan. It can be harvested 20 days after sowing, harvesting 910 times and yielding 1000 kg per mu. The yield of pea seedlings mainly depends on the seedling base, with 135kg of seeds per mu, 1500 kg of farm manure, 100kg of plant ash and 25kg of calcium superphosphate before sowing. After intensive cultivation, it was arranged into a 1.3-meter-wide flat bed, and the direct seeding was carried out according to the row spacing of 10 Mel 15 cm. After sowing, the soil was covered with 1 Mel 2 cm. All the seedlings emerged in 7 days in early spring, and the seedlings were covered with soil 2 times and 3 cm after emergence. In the seedling stage, it is necessary to topdressing and watering in time, keep the soil dry and wet, and weed before closing. About 2 true leaves should be timely applied quick-acting nitrogen fertilizer, one time for each harvest, 4 kg of urea to water to 0.3%, a total of 4 Mel 5 times, and 0.2% potassium dihydrogen phosphate. During this period, it is mainly to control yellow top disease, powdery mildew, aphids and leaf miners that harm leaves.

30 days after sowing, the seedlings were harvested at one time when the seedlings were 8ml / 9cm in length, and the roots were planed, bundled, cut off the basal roots of the stem, washed and listed on the market. When the seedlings were harvested many times, the shoots were picked when the seedlings were 20 cm high and 7 Mel had 8 true leaves. When the stipules are not opened, the tender shoots of the upper compound leaves are harvested, together with two undeveloped young leaves, which can be harvested once every 10 days, and the net income per mu can reach 10,000 yuan.
