In an interview with Baocheng Subdistrict in Changle County, the reporter saw that when many vegetable farmers cultivated the summer pepper seedlings, in order to prevent the pepper seedlings from becoming too large during planting, they used the method of frequently moving plugs to control the growth of the seedlings, which was easy for the pepper seedlings. The growth has caused many adverse effects. The first is serious injury. Because of the limited space available for the use of plugs, when the roots grow to a certain extent, the roots of the pepper grow out of the permeated holes at the bottom of the tray and grow rooted in the soil of the nursery bed. When the vegetable growers frequently move the plug, they will put the bottom of the pepper seedlings. All of the roots are cut off, making it impossible for the root system to absorb enough water and fertilizer for a short period of time. At the same time, the root system of capsicum is underdeveloped and its regenerative ability is weak. After the root system is injured, new roots grow slowly. The depth of the reentry bar is also limited, resulting in low resistance to the pepper. The wounds formed when the roots of the seedlings are transplanted are also susceptible to pathogens. If the peppers are infected with root diseases, especially the diseases such as Phytophthora root rot, it will cause a large area of ​​dead trees after the colonization of peppers. Followed by the easy formation of young old seedlings. The seedling period of pepper is too long, the stems of seedling seedlings appear woody, the leaves turn yellow, the root growth rate is slow, and the ability to germinate new roots becomes weaker, which will lead to slow seedlings slowing when planting, and the growing tendency of the peppers becomes weaker. Again, poor flower bud differentiation. When the pepper seedlings grow from 3-4 true leaves, flower bud differentiation begins. If the seedlings are frequently moved, the roots will be seriously damaged and the nutrient supply will be insufficient to cause poor flower bud differentiation. After the planting, there will be many malformed fruits. The output is low. Therefore, pepper cannot be frequently moved during the seedling raising of peppers. If the seedlings grow too early due to premature nursery, they can be moved to larger nutrition cups. This can reduce the number of moving plugs and avoid them. Move the plug to injure the root and affect flower bud differentiation. When the pepper seedlings reach 5-8 leaves, they can be planted.
