Moreover, you may combine the method of press-molding the convex-shaped or concave embedded line 7, and the method of printing or apply | coating.

  As shown in FIG. 3, the insect-proof cover 9 is formed in such a size and shape that the upper end side opening 2 b of the cover body 2 is covered with a material such as a non-woven fabric having air permeability and flexibility. After being cut into a circle, a rubber string 9a having elasticity is sewed along the outer peripheral edge of the nonwoven fabric, and finished in a hair cap shape as shown in FIGS. Thus, the cover main body 2 is provided so as to be freely expanded and contracted according to the size and shape of the upper end side peripheral surface. The rubber string 9a may be bonded along the outer peripheral edge of a circular nonwoven fabric. Further, at the time of papermaking, a non-woven fabric having a circular shape may be made.

  The illustrated embodiment is configured as described above, and a method for embedding the plant cultivation cover 1 will be described below.

  First, as shown in FIG. 4, each retaining piece 4... Of the plant cultivation cover 1 is radially bent toward the outside and protrudes outward from the outer peripheral surface of the side portion of the plant cultivation cover 1. 1 is held in a posture in which the upper end side opening 2b of the plant cultivation cover 1 is directed upward and the lower end side opening 2a is directed downward.

  Next, as shown in FIG. 5, after piercing the tip of the excavation protrusion 3 formed on the lower end side of the plant cultivation cover 1 perpendicularly from above to the planting surface of the soil A that has been leveled such as a field, The plant cultivation cover 1 held by hand is horizontally rotated around the axis C of the cover body 2 in the right direction or the left direction. Alternatively, the soil A where the plant B is planted by the excavation protrusion 3 of the plant cultivation cover 1 is centered on the axis C of the cover body 2 by rotating forward and backward alternately in both the right direction and the left direction. As drilling into a circle.

  While excavating the soil A where the plant B is planted, the entire plant cultivation cover 1 is pushed down in the direction in which the lower end side of the plant cultivation cover 1 is embedded in the soil A, and the plant cultivation cover 1 The desired depth is embedded in the soil A where the plant B is planted (see FIG. 6). Thereby, the excavation work for excavating the soil A where the plant cultivation cover 1 is embedded and the operation for embedding the plant cultivation cover 1 at a desired depth with respect to the soil A can be easily and easily performed. 1 can be securely embedded and fixed in soil A. Moreover, since the plant cultivation cover 1 is embedded and fixed to the soil A without using an excavating tool such as a scoop, the work and labor required for embedding and fixing the plant cultivation cover 1 can be saved, and workability can be improved. be able to.

  Moreover, as shown in FIG. 6, the embedded line 7 is hidden in the soil A at the lower end side of the plant cultivation cover 1 or is embedded at a depth matching the surface of the soil A, and then the embedded line 7 is hidden. The soil inside and outside the plant cultivation cover 1 is replenished, the soil outside the plant cultivation cover 1 is stepped on, and the soil inside is moderately solidified with a hand or a stick. Thereby, the plant cultivation cover 1 can be accurately and reliably embedded at a depth at which the lower end side of the embedded line 7 is submerged in the soil A. In addition, the soil A containing compost, fertilizer, etc. is put inside the plant cultivation cover 1.

  When the operation of embedding and fixing the plant cultivation cover 1 in the soil A is completed, the plant B is inserted from the upper end side opening 2b of the plant cultivation cover 1 and surrounded by the plant cultivation cover 1 as shown in FIG. Planted in the center of the soil A. Thereafter, water is supplied to the soil A inside and outside the plant cultivation cover 1.
