Description

Seedling transplanting protection device for municipal greening

technical field

The invention belongs to the technical field of seedling transplanting, in particular to a seedling transplanting protection device for municipal greening.

Background technique

Municipal departments often need to transplant seedlings to designated ground in urban greening projects. The root system of the newly transplanted seedlings has not yet taken root in the soil layer of the newly transplanted site, so it is necessary to support and protect the transplanted seedlings to avoid tilting and toppling under the action of wind load.

In the prior art, wooden stakes or metal pipes are generally used to support the seedling trunks, which is inconvenient for installation. Moreover, the bark of the trunk of the newly transplanted seedlings is prone to dryness, cracking, and bursting. In severe cases, it will rot and grow white bacteria. If left unattended, the area will become larger and the growth of the seedlings will become weaker. Severe death occurs. This situation is mainly due to the short transplanting time of seedlings, the root system is not fully developed, absorbs and transmits water, the nutrients are not sufficient, the body is in a slow seedling state, and the resistance is relatively weak. At this time, after sunlight Direct sunlight will cause serious water loss on the west or south side of the trunk, dehydrating the bark, and then shrivelling, cracking, and bursting of the bark. Symptoms of wood rot such as white or gray bacteria will appear after being soaked in rain and eroded by pathogens. To solve such problems, use a fungicide to spray the trunk and wounds to kill the white bacteria. But, when carrying out supporting protection to nursery stock with protective device, it is inconvenient to spray fungicide to transplanted nursery stock trunk. Just there is above-mentioned technical problem as the patent document of CN218184377U as authorized announcement number.
