Some people say that green onions grow faster when they are cut before transplanting, is that right?
Planting time: In Yantai, our peninsula, sowing is usually done after the first year of the autumnal equinox. At the end of May next year, we are busy sowing before and after the wheat harvest until the onion seedlings grow to about 20 cm. After energy storage in winter and differentiation in spring, onion seedlings will quickly enter the reproductive growth period after transplanting. The following farmers share with you the method of transplanting green onions by our farmers. When transplanting onion seedlings, we should first select the seedlings and classify the thickness of onion seedlings, which is convenient for unified management after planting. After the saplings are sorted, cut three or four centimeters of leaves from the center of the onion. Then, the question comes, why do you want to cut onion seedlings when transplanting green onions?
One reason is that the root system of Welsh onion seedlings is seriously injured when bolting, and the ability to absorb water and nutrients is stagnant, which can not meet the water and nutrients consumed by leaves after dinner. Therefore, if plants can't provide enough nutrition, limited water and nutrients will give priority to the growth and development of new leaves. At this time, the leaves that grow before dinner often quickly age, wither and turn yellow due to lack of water and nutrition, and it is difficult to play the role of leaf photosynthesis. Plants must carry out photosynthetic transformation on newly grown leaves before they can develop into green onions. Therefore, in order to make the transplanted onion seedlings survive as soon as possible, some hairy leaves should be cut off to reduce the evaporation of water on the leaves, and then cultivated. This is beneficial to the rapid seedling formation and growth of plants.
The advantage of cutting some leaves before transplanting green onion seedlings is that it can improve planting efficiency. By reducing the leaves of onion seedlings, it is not easy to damage the plants during transportation after pulling out the seedlings, thus improving the planting speed and working efficiency. Therefore, when transplanting scallion, partially cutting off the leaves of scallion seedlings will not only affect the growth of scallion seedlings, but also be more conducive to the rapid growth of scallion seedlings.
In order to ensure the yield and quality of green onions, the selection of planting sites is very important. When stopping selection, we should first pay attention to avoid planting green onions on plots or stumps of the same crop to avoid the harm of underground pests and diseases of the same crop to green onions. Welsh onion has strong adaptability to the environment, and the requirements for field planting are not strict. However, due to the excellent yield and quality of green onions, it is best to choose sandy soil with sufficient sunshine, convenient irrigation, fertile soil, good air permeability and rich organic matter when planting.
