Onion Seedlings Grasp the "Four Measures"
Choose the best Choose new seeds with fast growing speed, strong lodging resistance, light blue long, short growing period, not easy bifurcation, and good commercial quality, such as Zhangqiu Indus, Chinese giant onions and Hebei giant onions. The average block yields over 5,000 kilograms of fresh onions. Select fertilizer Nursery fields should be selected for deep, fertile, easy-flowing, loamy loam or sandy loam soil, and the former had not been planted with onion, garlic, leeks, and other liliaceous vegetable plots. Combining 6,000 kg of high-quality farmyard fertilizer and 30 kg of compound fertilizer in Mushi, the land is well-mixed and well-mixed to make 1-1.5-meter-wide and 10-meter-long rakes for field management. Timely sowing Scallion spring sowing seedlings, from sowing to planting time is short, so proper early sowing is essential, sowing in late March. The average sowing rate of 2.5-3 kilograms per mu can be planted on 6 acres of land. Spreading methods are used to sow pods before sowing. After the water is soaked, the seeds are mixed evenly with appropriate amount of ash or fine dry soil and repeatedly broadcasted several times to facilitate even distribution of the seeds and then covered with 0.5 cm thick fine soil. You can also sprinkle the seeds first. The iron rakes can be used several times. Both methods are finally covered with plastic film, which not only warms and moisturizes, but also emerges early. It usually emerges 6-7 days after sowing and emerges 1-2 days earlier. Field management When the onion sprouts halfway out, uncover the mulch to avoid burning the seedlings. After the seedlings were found, the spotted shoots on the onion seedlings were found to be seeded early to ensure that each onion seedling had roughly the same nutritional area. During the period of growth, a management method based on promotion is adopted, where small water is poured, less fertilizer is applied, and soil is kept moist to ensure nutrient supply. As the temperature rises, onion seedlings gradually grow, the demand for fertilizer and water increases, and the amount of watering and topdressing should also increase accordingly. Generally, each time watering 30-40 cubic meters/mu, topdressing urea 5 kg. During weeding, weeds should be carefully controlled and can be removed manually. Herbicides can also be used for removal. At the same time, pay attention to the control of mantle, reduce the rate of weak seedlings, ensure that the onion seedlings groups grow neatly and consistently, and the individuals are stout. One week before planting, stop watering and exercise the onion seedlings, which will help to rejuvenate the seedlings as soon as possible after planting.
