Technical Field
[0001] This utility model relates to the field of rodent-proof devices, and in particular to a temporary rodent-proof device for seedling cultivation. Background Technology
[0002] During the sowing of hybrid fruit tree germplasm resources, rootstock seed sowing, and seedling grafting, research or production bases face a thorny problem: the roots and stems of seedlings or grafted seedlings after germination are easily gnawed by rats, leading to plant death. Since the resources sown are mostly obtained the previous year through hybridization and pollination, these germplasm resources are hard-won, and it is a great pity that they are easily damaged by rats. Currently, rat control in bases or farms mainly relies on baiting the surrounding area or setting rat traps and sticky boards. However, these methods cannot completely prevent rat damage and are not very effective. To protect important germplasm materials, rat-proof netting greenhouses can be built, but setting up dedicated rat-proof greenhouses is costly, has little effect during non-rat-prone periods, and is inconvenient for daily maintenance.
[0003] Therefore, how to provide a temporary rodent-proof device for seedling cultivation that is suitable for greenhouses or open-air locations, easy to install and reusable, can be installed during the critical period of seedling growth and removed when the seedlings have grown thicker and are less susceptible to rodent damage; and does not interfere with normal watering and spraying during use is a problem that urgently needs to be solved by those skilled in the art.
