Many vegetable farmers used the method of cutting the upper leaves to achieve better results when planting green onions. According to local farmers, this method can significantly increase the rate of seedling easing, which is conducive to the growth and development of welsh onions and increases the output of welsh onions.
Compared with the traditional whole planting method, the leaf cutting method has many advantages.
First of all, cutting leaves to reduce the seedlings of the leaves, is conducive to post-shooting transplants, planting and other agricultural operations, not easy to plant damage, can speed up the rate of planting and improve work efficiency.
Secondly, cutting the leaves and planting can reduce the water and nutrient consumption of the seedlings, which is beneficial to the rapid seedlings of the onion seedlings. When the green onions were transplanted and transplanted, the roots were seriously injured, and the ability to absorb water and nutrients was in a stagnant state, which could not meet the water and nutrients consumed by the leaves after planting. In the case of plants unable to provide adequate nutrition, limited water and nutrients will preferentially supply the growth and development of new leaves. The leaves that grew up before colonization are often rapidly aged and yellow due to lack of water and nutrients, and it is difficult to exert the effects of the leaves. After the planting, we can see that we can see that the onion cultivars that finish the seedlings are mostly dry and yellow. They lose the effect of the leaves and rely on the newly grown leaves to grow quickly. In addition, when the green onions are colonized, the onion seedling leaves are severely damaged. After the planting, the leaves are affected by the wind, water flow, etc., and the plants are prone to lodging and other problems, which is not conducive to the growth and development of the onion. Therefore, it is entirely feasible to remove old leaves and large leaves when planting green onions, which is more conducive to plant seedlings and growth.
The specific practice of leaf cutting and planting is as follows: After the seedlings are pulled out, the seedlings are neatly tied into small bundles, and then the upper part of the leaves are cut off with a file, leaving only the lower part of the “light blue†and about 10 cm. Onion leaves. In this way, the onion leaves become shorter, smaller, easier to move, and less damaged, which is conducive to keep the onion sprouts robust. The rapid establishment of onion shoots also ensures that the plants stand upright, the leaves evaporate less, and the burden on the roots is light, which is conducive to the rapid emergence of new roots, new leaves, and slow seedlings.
