In production, cucumbers take advantage of pumpkin grafting. The reason is that pumpkin roots are well-developed and have strong water-absorption and absorption capacity. They have good resistance to disease and stress, can effectively increase the growth of cucumber vines, and enhance their ability to flower and sit, avoiding them. Plant premature aging. According to the reporter's understanding, at present, the two kinds of grafting methods, which are based on the connection method and the top connection method, are the most commonly used methods.
Since there are many benefits of cucumber grafting, then we must give full play to the advantages of grafting to ensure that cucumber grafted seedlings thrive, not because of improper management and rootstock pumpkin growth potential than the growth potential of cucumber, affecting the grafting effect. For cucumber seedlings, if the roots are continuously rooted or rooted and then rooted or rooted and dragged, they will have an impact on the scions and even lose the significance of grafting. For the top grafted seedlings, the growth point of the pumpkin is not completely removed, and even the growth point of the rootstock pumpkin exceeds the growth point of the scion cucumber to form a “vicious competitionâ€, which is not conducive to the cultivation of robust cucumber plants.
Therefore, to manage grafted cucumber seedlings, the roots should be cut off in time, and the growing point should be removed in time when the growth point is removed, so as to ensure that the scion cucumber grows. In production, in order to shorten the easing time, it is better to stick to the root before planting. If you do not grasp this opportunity, you need to take root after planting the seedlings. According to the growing trend of seedlings after planting, it is generally 5-7 days after planting. Its growing point begins to grow yellow and long leaves. When the roots start to lower, they can be cut off. The roots should be selected at about 4 o'clock in the afternoon on sunny days. After the break, it will help the seedlings. When the roots are cut off, the blade can be cut at 1 cm below the cucumber grafting interface and it must be completely removed. In addition, if the head of the pumpkin has a sprouting heart, it should be removed at the same time, it is best to break off from its base. For the top-jointed seedlings, a more thorough “pick-up†work should be carried out within 1 week after planting, in order to eliminate the growing point of the pumpkin and ensure the normal growth of the cucumber scion.
