It is formed with a transparent or translucent polyester resin sheet (A-PET sheet). Moreover, you may color in the arbitrary colors suitable for the growth of the seedling C.

  Moreover, it is as follows when an example of each part dimension (refer FIG. 2) of the seedling protection cover 1 at the time of completion of an assembly in a taper cylinder shape is shown. The diameter D1 of the upper end side opening 4 of the seedling protection cover 1 is set to about 250 mmπ, the diameter D2 of the lower end side opening 3 is set to about 350 mmπ, and the total height H of the seedling protection cover 1 is set to about 450 mm. However, it is not limited to the above numerical values, and can be changed to an arbitrary size corresponding to the type of seedling C and the like.

  In addition, a mark serving as a guide for the embedding position in the soil A may be provided in advance on the lower end side outer wall portion embedded in the soil A of the seedling protection cover 1. For example, if a mark is previously provided at an upper position (a position of about 100 mm) separated from the lower end of the seedling protective cover 1 by a predetermined dimension, the lower end of the seedling protective cover 1 is embedded in the soil A up to the position of the mark. Thus, it is possible to accurately embed only a predetermined embedding size. Further, instead of the mark, for example, a concave part or a convex part may be formed, or a scale may be printed.

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

  First, as shown in FIG. 6, the tip of the digging tool B having a substantially semicircular shape or a substantially circular shape is pushed substantially vertically from above with respect to the planting surface of the soil A that has been leveled, such as a field. After forming the substantially circular groove part Aa in which the lower end part of the seedling protection cover 1 having the tapered cylindrical shape shown in FIG. 7 is allowed to be inserted on the planting surface of the soil A, as shown in FIG. Plant eggplant seedling C. The digging tool B may be rotated while being pushed into the planting surface of the soil A to form the groove Aa.

  In addition, it is as follows when an example of each part dimension (refer FIG. 6) of groove part Aa formed with the said digging tool B is shown. The groove width W1 at the upper end of the groove portion Aa is formed at about 20 mm, the groove width W2 at the lower end of the groove portion Aa is formed at about 10 mm, and the groove depth W3 is formed at about 100 mm. Alternatively, the size may be changed to an arbitrary size corresponding to the size of the seedling protection cover 1.

  Next, after the seedling protection cover 1 folded into a substantially flat state shown in FIG. 5 is spread and assembled into a tapered cylindrical form shown in FIG. 1, each bent portion formed at the lower end of the seedling protection cover 1 6 are bent toward the outside (or inside) along the folding ruled line E by approximately 90 degrees, and then the lower end portion of the seedling protective cover 1 is viewed from above with respect to the groove portion Aa of the soil A as shown in FIG. Insert it almost vertically and push it in by a predetermined embedding dimension.

  Next, as shown in FIG. 9, the soil A around the groove portion Aa is put in the gap between the lower end side outer wall portion of the seedling protection cover 1 and the groove portion Aa, and the soil A on the lower end side outer periphery portion of the seedling protection cover 1 is placed. Step on. Alternatively, the seedling protective cover 1 may be pressed into a gap between the lower end side inner wall portion and the groove portion Aa and pressed. The seedling is removed when it has grown to some extent and protection by the seedling protection cover 1 is no longer necessary.

  Moreover, since the lower end side opening part 3 embedded in the soil A of the seedling protective cover 1 is wider and the bent parts 6... Bent to the outside of the lower end part are locked in the soil A, the removal direction It is possible to prevent the seedling protection cover 1 from falling out of the soil A or tilting during strong winds.

Then, the upper end side opening 4 is adjusted to a desired size, or closed in a sealed state, and adjusted to a temperature suitable for the growth of the seedling C, ventilation, and the like.

  Further, if the seedling C becomes a little larger, the upper end side walls 1a, 1a of the seedling protection cover 1 are raised outward, and the upper end side opening 4 is opened in a fully open state. The part 4 can be easily adjusted to a size suitable for the growth of the seedling C in consideration of the temperature, weather, seedling growth conditions, and the like.

  As a result of using the seedling protective cover 1 to protect the eggplant seedling C, for example, when a storm with a wind speed of about 10 m to 15 m is applied for about 2.5 hours, the seedling protection cover 1 and the eggplant seedling C are applied. There were no breaks, damage or pain.

  In addition, when the growth state of the seedling C protected by the seedling protection cover 1 and the seedling C not protected by the seedling protection cover 1 are compared, when about 40 days have passed since the seedling C was planted, the seedling protection cover The seedlings C protected by 1 showed an average growth of 15%, but the seedlings C that were not protected by the seedling protection cover 1 grew poorly. In addition, the seedling C protected by the seedling protection cover 1 was not damaged by pests and was zero. However, about six seedlings C that were not protected by the seedling protection cover 1 were confirmed to be damaged by pests.

  It is clear from the above experimental results, and if the seedling C is protected by the seedling protection cover 1, the result that good protection and good growth of the seedling C can be achieved.

  As described above, the tapered cylindrical seedling protective cover 1 in which the opposite end portions of the resin sheet 2 are integrally bonded is embedded in the soil A to protect the seedling C surrounded by the protective cover 1. Therefore, there is no gap or breakage in the joint part of the seedling protective cover 1, and there is little breakage, damage, pain, etc. of the seedling C even in the wind and rain, and pest damage to leaves, stems, etc. There are few, and the heat retention effect at the time of low temperature can be acquired.

  Moreover, since the upper end side opening 4 of the seedling protective cover 1 is opened, there is no sudden temperature rise in the seedling protective cover 1 even in fine weather, and good protection and good growth of the seedling C can be achieved. it can.

  In addition, the taper-shaped seedling protective cover 1 is folded in a substantially flat state along each of the two folding ruled lines D and D, so that the joint portion is not damaged during assembly and folding, and can be used any number of times. Can be cheap. In addition, when a plurality of seedling protective covers folded in a substantially flat state are stacked when not in use, the storage space can be reduced, and handling and management can be performed easily.
