Onion autumn seedlings generally sowed in early September, early spring and easy convulsions, too late to be frozen to death; winter before the seedlings with 2-3 leaves, plant height of 10 cm, false stem base 0.5 cm or less. Seed treatment: soak the seeds in clean water for 10 minutes, remove the seeds and remove the impurities, and then put the seeds into hot water at about 65 degrees for 20-30 minutes and stir continuously. Seed soaking can be unearthed 1-2 days in advance. Sowing with fresh seeds of the same year, sowing rate of 3-4 kilograms per acre, can be planted 6-8 acres of land; if you use the last year of Chen seeds should be more than double the amount of seed, more than two years of seed can not be reused. When sowing can be spread and drilled. The seedbed is filled with bottom water and evenly sowed, then covered with fine soil about 1 cm. Drilling is carried out in a shallow groove with a depth of 1.5-2 cm at a distance of 12 centimeters within the raft. The seeds are sown in the ravine and the raking is done. Before and after the management of scallions to maintain seedlings wet to ensure the normal emergence of seedlings. After emergence, until the winter, generally no drought or water, according to the use of base fertilizer and growth of seedlings watering fertilizer. Pour frozen water before freezing. When the average temperature rose to 13.5 degrees on the same day when the onion returned to green, the water began to return to Qingshui, and green manure was applied at the same time; thereafter, the seedlings, cultivators, water control, and seedlings were planted for 12-15 days. After the seedlings, the onion pods will enter the vigorous growth period, and 2-3 times of watering top dressing will be carried out during this period. Apply 20-30 kg urea per acre. The seedlings between the seedlings are generally divided into two stages; the autumn seedlings are planted in the slow seedling stage after the second year of pouring and returning to Qingshui. The seedling distance is maintained at 2-3 cm; the second time is when the seedling height is about 20 cm. About 140,000 acres of actual seedlings. The drilled seedlings can meet the above requirements and reduce the distance between the plants to maintain sufficient nutrient area per plant.
