There is a problem that the necessary moisture cannot be obtained. Techniques such as those disclosed in Patent Documents 1 to 9 have been proposed to solve such problems. However, even in these techniques, it is difficult to say that the growth of planted plants is sufficiently secured.
For example, construction methods using climbing plants are often used in retaining walls, factories, warehouses, multi-level parking lots, etc., but it takes a long period of several years to complete the greening, resulting in a decrease in the amount of greenery on the lower part of the wall and an upper part of the wall. Excessive growth of vegetation and deviation of plants from the walls where greening is to be applied are often observed.
In addition, the wall base type construction method, in which a base planted with plants is attached to the wall of a building, is used in buildings with many users, such as stations and commercial facilities. There are problems such as securing the required period, poor growth due to insufficient capacity of the base, insufficient greening in the upper part of the green base due to uneven water supply, excessive growth in the lower part of the green base, and withering due to malfunction of the watering system.

[Reference test example] Examination of water retention in various materials Based on the knowledge that sphagnum moss has better water retention than fiber medium A, a test was conducted to select a material having higher water retention than sphagnum moss. Hydrophilicity was also investigated.
● <Materials and test methods>
(1) Water retention test (i) Fiber medium A, fiber granules B, and fiber medium C (fiber medium A: fiber granules B = mixed in a predetermined volume ratio ranging from 40: 60 to 60: 40 medium) was prepared.
(ii) 1 L of each of the above three culture media was weighed, filled into a non-woven fabric bag, and then weighed (referred to as "weight before treatment a").
(iii) Each medium was immersed in a bucket filled with tap water, and pulled out when the water was sufficiently spread.
(iv) Each culture medium pulled up was suspended from a hook, and the weight after immersion for 65 hours (referred to as "post-treatment weight b") was measured.
(v) From the weight of a (g) and b (g), calculate the post-treatment moisture content (ba) (g) and weight-based moisture content [(ba) / b × 100 (%)], used as an index.

(2) Hydrophilicity test (i') (1) Prepared by the same procedure as (i) and (ii) in the water retention test. The weight before treatment in the hydrophilicity test is defined as c.
(ii') Each culture medium was immersed in a bucket containing tap water, quickly taken out, and weighed (referred to as "post-treatment weight d").
(iii') From the weights of c(g) and d(g), the post-treatment moisture content (dc) (g) and the weight-based moisture content [(dc)/d x 100 (%)] were calculated.

● <Results>
(1) Water retention test The water content (ba) after treatment and the weight-based water content [(ba)/b × 100] were higher in the order of fiber granules B, fiber medium C, and fiber medium A (Table 1). Fiber grain B, which showed the largest value, has extremely high water retention in the fiber itself. Therefore, it is considered that the fiber medium C mixed with the fiber granules B has clearly improved water retention as compared with the fiber medium A.
(2) Hydrophilicity test Similar to the results of the water retention test, the water content and weight-based water content after treatment were higher in the order of fiber grain B, fiber medium C, and fiber medium A (Table 2). Since the fiber grains B exhibited high hydrophilicity, it is considered that the hydrophilicity of the fiber medium C mixed with the fiber grains B was clearly improved.
Excessive moisture in the medium of plants causes root rot and the generation of anaerobic bacteria, so a suitable air layer (gas phase) is required in the medium. It was suggested that the fiber medium C is the optimal mixed medium that meets the plant's water and gas phase requirements.

[Example 1]
A planting material for wall greening of the present invention was produced in the following manner.
That is, fiber grains (fiber grains B) made of core-sheath type composite fibers in which polyethylene terephthalate is coated with polyethylene are added to the fiber medium A in a predetermined volume ratio in the range of 40:60 to 60:40. Then, artificial zeolite, charcoal, and perlite were mixed as fertilizer preservatives in amounts that would produce the desired effects in the present invention, to obtain the above-mentioned fiber medium C. The fiber medium A was used in a volume ratio larger than that of the fiber granules composed of core-sheath type composite fibers coated with polyethylene terephthalate.

[Example 2]
A base material for wall greening of the present invention was produced in the following manner.
One type of non-woven fabric bag forming a rectangular parallelepiped, three types of reinforcing materials (needle punch mats), and two types of water-conducting mats (semi-synthetic fibers made of pulp) were prepared and assembled (Fig. 3), as shown in Fig. 2. A base material for wall greening was produced as a rectangular parallelepiped having a rectangular surface approximately flat with a height of 54 cm×a width of 54 cm and a thickness of 9 cm.
Fiber medium C was used as a planting material for wall greening. The blending amount of fiber medium A and fiber grains B in fiber medium C is more than fiber medium A, and the amount (volume) of fiber medium A does not exceed 60% of the total volume of fiber medium A and fiber grains B. A fiber medium C was made up in the specified amounts.

The presence or absence of a vegetation mat (reinforcing material) and a water-conducting mat in the plant material and base material used were as follows (Table 3). The base material for wall greening was manufactured by the same method as shown in Example 2 (Figs. 2 and 3).

In each plot, seedlings of the plants shown in Table 4 below were planted in the following amounts per base material, and the growth of the seedlings of each plant was investigated under normal watering management. The test was conducted in a single series.

For each test plot, the plant soundness was periodically visually evaluated on a 6-point scale from 0 (completely dead) to 5 (healthy).

● <Results>
The planting materials for wall greening of the present invention (Examples 1 to 4) maintained plant growth even after 14 months (Fig. 5).
