The area planted with onions in our country is also very large now, and the cultivation techniques are relatively mature. However, when growing onions, seedling raising and transplanting are usually the main approach. Seedling raising and transplanting can improve the growth ability of the seedlings, increase yield and improve quality. So below, the editor brings you the onion seedling-raising techniques. Let's take a look together!</p> <p></p> <p><strong>1. Choose a superior variety</strong></p> <p>Before raising seedlings, you must first choose an excellent onion variety. A superior variety has a very big relationship with the later growth and yield of the onion. Therefore, the choice of variety is very important. When planting, we should pay attention to choosing varieties with strong growth, high yield and strong disease resistance. The main varieties on the market now are purple-skinned onions such as Ziyu and New Red Star. The yields of these onions are all relatively high. Under normal planting management, their yield can reach 5000 kg/mu, and on some high-quality plots the yield will be even higher.</p> <p></p> <p><strong>2. Seedbed preparation</strong></p> <p>Before raising seedlings, prepare the seedbed. The seedbed soil must be ensured to have sufficient fertility, be deep and loose, and have strong water and fertilizer retention, and it must not have grown crops of the same family for at least two years. Control the area of the seedling bed well, then prepare the land by deep plowing, with the deep plowing depth controlled at about 25-30 cm. Then apply sufficient base fertilizer in coordination, with the base fertilizer mainly being fully decomposed farmyard manure, along with compound fertilizer. Mix the fertilizer and soil thoroughly to improve fertilizer utilization. Finally, make beds and water them, then wait for sowing.</p> <p></p> <p><strong>3. Sow at the right time</strong></p> <p>The sowing time is closely related to the growth of the seedlings and will directly affect the yield and quality of the onions. If sown too early, it will prolong the growth period of the seedlings, causing excessive nutrient consumption and excessive uptake, making the seedlings prone to bolting. If sown too late, the resistance of the seedlings will decline and their cold tolerance will be insufficient, making them prone to freezing damage and dead seedlings during overwintering. Therefore, when sowing, pay attention to the sowing time. The specific sowing time is determined by various factors such as the planting region, variety and weather changes. For example, in the central-south region, sowing is generally done about 3 days after White Dew. After sowing, cover with fine soil, then use an appropriate amount of herbicide and do a good job of weed control.</p> <p></p> <p><strong>4. Seedling-stage management</strong></p> <p>After sowing, cover with rice straw to improve the soil's moisture and heat retention capacity and provide appropriate rain protection, then keep the soil moist before the seedlings emerge from the soil. When about 65% of the seedlings have emerged, the rice straw can be uncovered, then water appropriately according to weather changes to prevent soil crusting from affecting seedling growth. Then apply topdressing reasonably, and cultivate the seedlings through water and fertilizer management. When managing the seedlings, it is necessary both to prevent the seedlings from growing too large and causing early bolting, and to prevent the seedlings from being too weak and reducing their resistance. Then, when the seedlings have grown about 4 true leaves and the plants are about 22 cm, they can be transplanted.</p> <p></p> <p>The above is a brief introduction to the key points of onion seedling-raising techniques. Onion seedling raising is a relatively important part of the onion planting process. We should try to avoid using the open-field direct seeding method, enhance the growth ability of the seedlings, increase yield and expand the economic benefits of planting. That is all for today's introduction. This article is for reference only. Thank you everyone for reading and supporting.</p>
