Before the planting of large green onions: the use of irrigation and drainage is convenient, and the thickness of cultivation is thick. In the past 3 years, no onions, onions, garlic, and leeks have been planted. The north and south are open to the ditch. The distance between the trenches is 80 cm, and the depth and width of the ditch are 30-35 cm. , Spread the earth at the bottom of the ditch with mixed fertilizer, Mushi urea 20 kg, 20 kg of diammonium phosphate, potassium sulfate 10 kg, the bottom of the trench has a width of 15 cm, a depth of 25 cm of loose soil preparation. The ridgebacks will be patted to make it easier to stand people when transplanting. The best transplanting period is in mid-June, but it will be completed in the end of the year. Before the seedlings were raised, they were poured with small water and carefully raised to prevent injury to fibrous roots. The residual seedlings with disease and insect pests were removed, and the strong seedlings with the typical characteristics of the variety were selected, sizing and grading, and planting with the seedlings. Generally 1.6 to 18,000 plants per acre are planted, that is, 80 centimeters in distance, planted in a single ridge, with a plant spacing of 5 centimeters, and a single plant nutrient area of ​​0.04 square meters. Each acre of green onions can be planted 4-6 acres of field. After the seedlings are transplanted, spraying a new high-fat membrane can effectively prevent surface water from evaporating, plant diseases and pests, and shorten the period of seedling sowing, quickly adapt to the new environment, and grow healthily. After the submerged ditch is ditched and the bottom of the ditch is loosened, the water can be drained by using a two-tooth hook or a small rake to the bottom of the earth. After the water is soaked, the green onion scorpion with a length of 40 cm, a diameter of 1.5 cm, and a split end is inserted into the onion. When inserting green onion seedlings and inserting green onion dumplings to pull out from the ditch, one hole, ie, onion eyes, is flashed, which is to be preserved, which is conducive to the ventilation and ventilation of the roots and light blues. Depth of planting: It is advisable to use the onion sprouts and leaves at a distance of 8 cm above the ditch surface.
