Description

  The present invention relates to a technique for planting a seedling on a planned planting site such as a shoulder portion of an expressway or a general road.

  When planting seedlings for planting on the shoulder of an expressway, conventionally, a method of digging a hole in the shoulder and planting has been adopted. However, since cables such as optical communication cables are embedded in the planned planting site on the shoulder of the expressway, when implementing the conventional method of digging holes and planting, cables resulting from planting holes In order to avoid this damage, trial digging for confirming the cable burying position is required in advance. However, the labor and cost required for this test excavation work are a heavy burden.

  Then, the construction method which plants a seedling without digging a planting hole in the place to plant is proposed (for example, refer patent documents 1, 2, and 3).

  Patent Document 1 includes an impermeable single-sided sheet and an other-sided sheet, the peripheral part of the single-sided sheet is covered with the folded part of the other-sided sheet, and the peripheral part and the folded part are between the water-permeable gap and the soil. It is integrated while maintaining the filling path, and a planting hole opening is provided in one side sheet, the other side sheet consists of two or more other side pieces, both adjacent side pieces have overlapping portions, and the overlapping portions are connected. A “planting bag” having a structure in which a non-integrated portion excluding a portion is temporarily fixed with a biodegradable yarn is described.

  If the planting bag described in Patent Document 1 is filled with soil and cultivated seedlings, and the cultivated seedlings are installed together with the “planting bag” in the planned planting site, a planting hole is dug. There are no seedlings.

  Patent Document 2 discloses a trapezoid in which a front sheet and a back sheet are integrated in a state in which both sides and long sides of a trapezoidal front sheet are covered by a peripheral edge of a back sheet that is larger than the front sheet. Is impervious, has a planting hole opening for inserting a seedling, and has an opening on the long side in parallel to the long side at a position avoiding the planting hole on the surface. In addition, one or more bags that communicate with the space between the front and back sheets are formed, the back sheet is water-impermeable, and has a structure with a permeable root that opens after a lapse of time from the time of installation. It has a “pave-surface planting bag”.

  The “pavement planting bag” described in Patent Document 2 is filled with soil and fixed to the planned planting site, and then a seedling is planted in the “pile surface planting bag” Then, the work of digging a planting hole can be omitted.

  In Patent Document 3, soil is enclosed in each bag-like body of a composite bag-like body formed by connecting a plurality of flat bag-like bodies made of corrosive fibers in the lateral direction, and each bag-like shape is filled in this soil. A “planting unit” is described in which seedlings for planting are planted through holes opened on the surface of the body.

  The “planting unit” described in Patent Document 3 is fixed to the planned planting site in a state of being filled with culture soil, similarly to the “slope surface planting bag” described in Patent Document 2, If seedlings are planted during the cultivation of the “planting unit”, the operation of digging a planting hole can be omitted.
