How to reduce the slow seedling time after onion transplanting?
The growth of onion requires roots to absorb nutrients and moisture. Whether it is planting in late autumn or planting in early spring, most of them are first cultivated and then replanted. This causes seedling transfer problems. How to improve the survival rate and enter the vegetative growth period as early as possible, there are the following methods for reference: 1, to ensure a certain soil temperature seedbed, sub-seedling within 3 to 5 days soil temperature can not be less than 18 °C. 2, seedlings should not be late as soon as possible, seedlings can be divided into seedlings when 1-2 true leaves, no more than 3 true leaves at the latest. 3. The seedling water should be poured the day before seedlings, which is convenient for raising seedlings, reducing root damage, and accelerating seedlings after seedling separation. Once the seedlings can not be too much, pay attention to shade, avoid seedlings too much water loss, combined with seedlings for seedling selection, requiring shallow planting, irrigation after planting, water should not be too large. 4, can use plant rooting agent, after the seedlings from the seedlings, the seedlings trapped together in the preparation of a good rooting agent mucus, so that the onion root and rooting agent full contact, which is conducive to early rooting of onions, but also to prevent onions Dead seedlings, rotten noodles and other phenomena. 5. The method of removing onion leaves from the seedbed can be adopted. This method is suitable for early spring colonization. Most of the seedlings planted in early spring are greenhouse nurseries in protected areas. The seedlings of these seedlings are not thick and long in length. They have a top-heavy, shallow-rooted feel. Two methods can be used to shorten the time for seedlings to grow slowly: One is to plant without the need for direct lifting from the seedlings. After the onion seedlings are graded, the upper leaves are cut with scissors at a height of one centimeter above the innermost heart. This will not only be beneficial to easing seedlings, but also conducive to rooting. To sum up, these methods can shorten the time for seedlings to be transplanted after transplanting onions and facilitate the early entry of onion into the vegetative growth period, which lays a solid foundation for high yield of onion.
