Afforestation disc and its producing method and construction method

Abstract

The invention provides a greening base capable of stably transplanting a plant without collapsing the root shape of a seedling of the plant and promoting the growth on rooting the plant artificially on a concrete surface of a roof top, or the like, and also to provide a method for producing the greening base without attaching materials to a mold on producing the same, and a method for installing the same. The greening base having water permeability and obtained by solidifying particle materials as layers with an adhesive curing material is provided by forming a plurality of planting holes positioned at prescribed intervals of a penetrating shape for approximately fitting to the root shapes of the planted seedlings so that the root shape of the seedlings grown in a seedling growing container is not collapsed, the lower end part of the root part shape attaches to a rooting layer of the greening base from the beginning of transplantation in the planting hole so that the plant is rooted in the planting hole in a state of maintaining the root part shape.

Description

technical field [0001] The present invention relates to a greening tray for artificially causing plants such as ground cover plants to take root and propagate on the roof of a concrete building, and its manufacturing method and construction method. Background technique [0002] In recent years, in cities and the like, lawns, ground cover plants, etc. have been planted on the roofs of concrete buildings, various concrete surfaces, etc., in order to secure a green area. [0003] In order to green such a concrete surface, there are problems such as water supply and water retention or ensuring nutrients when the concrete surface is dry, and various greening disks have been developed for this purpose. [0004] As an existing green disk, such as Figure 19 As shown in (a) and (b), the water-retaining layer 22 is set under the permeable greening plate 21 and placed on the concrete surface C. [0005] On such existing greening disc 21, as Figure 19 As shown in (a), the plant pit 2...

AI Technical Summary

Problems solved by technology

Generally, since the depth of the plant pit 23 is shallower than the root shape 10 of the seedling 9, there are problems as follows: Figure 19 As shown in (b), when such a root shape 10 is accommodated in the plant pit 23, the root shape 10 is destroyed, the root inside is cut off, and it takes a long time for the recovery of the root to grow. , the roots were blown away by strong winds before resuming growth

[0007] like Figure 19 Shown in (b), the seedling 9 that is accommodated in the plant pit 23 stretches the root due to growth, and its root mainly reaches the water retention layer 22 by the through hole 24 of the plant pit 23. However, in the existing greening disc, due to The through hole 24 of the plant pit 23 has a small diameter, and the fine-grained pumice layer constituting the water-retaining layer 22 has many gaps, and even if the water retention is good, the nutrient retention is also lacking. Therefore, the amount of roots 25 reaching the water-retaining layer 22 is small, slow plant growth

[0008] As the manufacturing method of the above-mentioned greening disc, when the stirring mixture of granular materials such as expanded styrene and the adhesive hardening material is filled into the mold box for layered solidification, there is the following problem: when the adhesive hardening material is solidified Finally, when the molded product is taken out of the mold box, the adhesive hardened material adheres to the mold box, stains the mold box, and it is troublesome to remove and clean.
