Key Points of Green Onion Transplanting Techniques
Site preparation before green onion planting: Choose plots with convenient irrigation and drainage, thick tillage, and no green onions, onions, garlic, and leeks in 3 years. Ditching in the north-south direction with a distance of 80 cm, and a depth and width of 30-35 cm. , The bottom of the ditch is evenly sprinkled with soil and miscellaneous fertilizers, 20 kg of urea, 20 kg of diammonium phosphate, and 10 kg of potassium sulfate are applied per mu. There is a loose soil layer with a width of 15 cm and a depth of 25 cm at the bottom of the ditch for planting. Beat the ridge back to pieces to make it easier to stand still when transplanting. The best transplanting period is mid-June, but the planting should be finished in the latter half of the year.
Before the emergence of seedlings, pour small water in the seedling box, take care of the seedlings to prevent damage to the fibrous roots, remove the residual seedlings with diseases and insect pests, select strong seedlings with typical characteristics of this species, grade them in size, and plant them as they emerge. Generally, 16,000-18,000 seedlings are planted per acre, that is, 80 cm furrow spacing, single ridge planting, plant spacing 5 cm, and the nutrient area per plant is 0.04 square meters. Each acre of green onion seedlings can be planted in 4-6 acres of field. After the seedlings are transplanted, spraying with a new high-lipid film can effectively prevent the surface water from not evaporating, prevent diseases and insect pests in the seedling stage, shorten the slow seedling period, quickly adapt to the new environment, and grow healthily. After spreading the ditch manure to loosen the bottom of the ditch, use a two-tooth hook or a small hoe to level the bottom of the ditch to drain the water. After the water seeps down, insert the green onion with a branch of onion that is 40 cm long, 1.5 cm in diameter, and forked at the top. When the onion branch is pulled out of the ditch, a hole flashes out, namely the onion eye, which should be retained to facilitate the root system and the white onion to ventilate. Allow it to blow in the sun, which is called the onion eye. The planting depth should be at least 8 cm from the center leaf of the onion seedling to the surface of the ditch.
