Description

Technical Field

[0001] The present invention relates to plants (including flower seedlings) molded into a sheet shape for use in mass planting.

Background Art

[0002] In mass planting, there is a technique of combining rooted plants (especially flower seedlings) like a bouquet. Specifically, from an aggregate of rooted plant seedlings, each seedling is separated as a unit, the soil is carefully removed, and a plurality of units are combined and planted together. Therefore, plants used for such mass planting may be stored as a sheet in a state where the seedlings are planted in a soil layer of about 10 to 30 mm so that they can be easily separated into units.

[0003] <{ As a technique for cultivating plants in such a sheet shape, for example, Patent Document 1 can be cited.

Summary of the Invention

Problems to be Solved by the Invention

[0005] [[ID=

[39] ]In Patent Document 1, by previously embedding plant seeds in the fluff part, the seeds are supported by the fluff part and the positions of the seeds are fixed, so that the sowing operation becomes unnecessary and a plant cultivation sheet that can facilitate plant cultivation is described.

[0006] According to the plant cultivation sheet described in Patent Document 1, although the sowing operation becomes unnecessary, nothing is mentioned about reducing the number of watering times and the handling properties such as carrying the plants.

[0007] Therefore, the objective of this invention is to provide a planting sheet that allows for a reduction in the frequency of watering, while also enabling plants to grow stronger, becoming less prone to wilting, thus making plant cultivation easier, and offering excellent handling advantages such as ease of transporting plants. [Means for solving the problem]

[0008] The present invention is as follows: [1] A planting sheet comprising a layer made of sponge material and a soil layer in which plants are grown. [2] The planting sheet according to [1], wherein the sponge material is a foamed synthetic resin. [3] The planting sheet according to [1], wherein the sponge material is AquaCell (registered trademark). [4] The planting sheet described in [1], wherein the plant comprises one or more species selected from baby's tears, thyme, pratia, clover, dwarf rock weed, moss, ivy, wire plant, sedum, veronica, dichondra, mint, glechoma, lysimachia, mondo grass, fern, and grass. [Effects of the Invention]

[0009] According to this invention, by retaining water in a layer made of sponge material, the plant grows by allowing its roots to penetrate the sponge layer. As a result, the plant absorbs the appropriate amount of water necessary for its growth at the right time. Consequently, the plant grows stronger, becomes less prone to wilting, and the frequency of watering can be reduced. Furthermore, because a layer of sponge material is provided beneath the soil layer, handling such as transporting plants becomes easier. [Brief explanation of the drawing]

[0010] [Figure 1] This is a perspective view of the planting sheet of the present invention. [Modes for carrying out the invention]

[0011] The embodiments of the present invention will be described below with reference to Figure 1. However, the present invention is not limited to these embodiments.

[0012] Figure 1 shows a planting sheet 10 according to the present invention. The planting sheet 10 includes a layer 1 made of sponge material and a soil layer 2 on which plants 3 are grown. More specifically, it is preferable that the planting sheet 10 includes a soil layer 2 on which plants 3 are grown and a layer 1 made of sponge material which is laminated below the soil layer 2 (on the side opposite to the side on which plants 3 are grown).

[0013] This configuration allows the roots of the plant being grown (3) to penetrate the sponge material layer (1). By placing a certain amount of water in a tray or similar container and immersing the sponge material layer (1) in it, the sponge material layer (1) retains water, and the roots that have penetrated the sponge material layer (1) are able to properly absorb the water necessary for their growth. As a result, even without frequent watering, a suitable growing environment for the plant can be maintained, leading to better plant growth, stronger plants, and reduced susceptibility to wilting.

[0014] Frequent watering can expose plants to excessive moisture. Excessive moisture can cause oxygen deprivation in the roots, leading to root rot. Furthermore, excessive moisture can hinder nutrient absorption, resulting in poor growth, such as yellowing or spotting of leaves. Using the planting sheet 10 with this configuration can prevent the above problems.

[0015] Furthermore, since layer 1, made of sponge material, supports the soil layer 2, handling such as transporting plants becomes easier, resulting in superior convenience.

[0016] The layer 1, which consists of sponge material, is preferably formed of a foamed synthetic resin with excellent water absorption and water retention properties. Examples of foamed synthetic resins include foamed urethane resin. From the viewpoint of being able to retain a sufficient amount of moisture and extend the watering period for the plant 3, the water absorption rate of the foamed urethane resin is preferably 50% or more, more preferably 90% or more.

[0017] In this embodiment, the sponge material layer 1 is preferably formed from AquaCell (registered trademark, manufactured by Hakusan Co., Ltd.) provided by Tokyo Flowerport Co., Ltd. With this configuration, it is possible to absorb more than three times, preferably about six times, the amount of water compared to, for example, a general foamed urethane resin. The layer 1 formed from AquaCell can preferably absorb more than 50% of its volume of water, more preferably more than 90%.

[0018] The water absorption rate of foamed urethane resin is calculated by weighing a sample of foamed urethane resin cut into 2cm x 2cm pieces (original weight) using an electronic balance, immersing it in 100g of deionized water at 25°C, retrieving the sample with tweezers after 1 hour, removing any moisture adhering to the surface, and then measuring the weight again (weight after immersion) using the following formula. Water absorption rate (%) = 100 × (Weight after immersion - Original weight) / Original weight

[0019] The thickness b of layer 1, which is made of sponge material, is not particularly limited, but for example, the thickness b is preferably 2 to 20 mm, more preferably 5 to 10 mm. The width c and depth d of layer 1 are not particularly limited, but for example, the width c is preferably 50 to 1000 mm, more preferably 100 to 500 mm, and the depth d is preferably 50 to 1000 mm, more preferably 100 to 500 mm.

[0020] The soil layer 2 is formed by spreading soil. The soil is composed of culture soil, lightweight soil, sawdust, etc. As the culture soil in this embodiment, basic soil commonly used for plant cultivation (such as red jade soil, black soil, river sand, etc.), improvement soil (such as leaf mold, peat moss, etc.), and adjustment soil (such as vermiculite, perlite, chaff con, zeolite, silicate clay, lime, plant ash, etc.) can be adopted, and natural soil or artificial soil can be used alone or in combination. Also, as the lightweight soil, inorganic artificial soil obtained from fired products of rocks such as perlite-based perlite, recycled ceramics, volcanic gravel, etc., organic artificial soil obtained by processing the bark of slow-decomposing coniferous trees (such as cedar and cypress), peat moss, grass peat, etc., or organic-inorganic mixed artificial soil obtained by mixing and processing organic materials with lightweight inorganic aggregates can be used. By using this lightweight soil, water retention and water permeability are improved. Furthermore, by using sawdust generated in a woodworking factory, etc., it can be used as a fertilizer for effective utilization of resources and growth promotion.

[0021] The thickness a, width c, and depth d of the soil layer 2 are not particularly limited. For example, the thickness a is preferably 5 - 50 mm, more preferably 10 - 30 mm, and the width c and depth d are the same as those of layer 1.

[0022] The plant 3 is not particularly limited as long as it is suitable for grouped planting. For example, baby tears, thyme, pratia, clover, baby fern, moss, ivy, wire plants, sedum, veronica, dichondra, mint, glecoma, lysimachia, jade dragon, fern, turf, etc. are preferable. By combining one or more of these plants, the appearance of the grouped plants can be improved.

[0023] The sheet for grouped planting according to the present invention can be used not only for grouped planting but also for various applications.
