Next, a method of spraying plant seedlings on a slope or the like using the spraying type planting greening apparatus having the above-described configuration will be described. The plant seedling is obtained by filling a growing tray 33 divided into cells shown in FIG. 6 with culture soil, and then directly cutting and rooting the vegetatively propagating plant. 35) is used.

The cell molded seedlings 35 are taken out of the growing tray 33 when they are appropriately enlarged, and are used. Therefore, rooted root mortars are formed and the soil is held on the roots, so that the roots can be stored for a long period of time. Yes, and especially good growth after spraying. In addition, mass production can be achieved in a short time as compared with conventional polypot cultivation seedlings. And cell molding seedling 35
In addition to the above, a manhole 2A is provided with a predetermined ratio of a fertilizer, a vegetation base material, a bonding material that can be more effectively attached to a slope, and the like.
And, if necessary, via the feed pump 28,
A predetermined amount of water is put into the tank 1.

In addition, since the present apparatus is provided with the stirring blade 4, a conventional lawn stem (a crawling stalk such as a sawgrass) or a seed can be applied to a slope or the like by the same operation as the conventional one. However, it is desirable that the rotation speed of the stirring blade 4 can be changed between the conventional lawn stem and the cell-molded seedling. Further, as the plant seedlings, pickled croaker, and cell molded seedlings grown on the growing tray 33 partitioned into cells, as an example, but depending on the plant seedlings,
Needless to say, it is not necessary to grow as a cell molding seedling. In addition, the rice chaff can be satisfactorily grown by mixing with the fertilizer or by mixing it alone and spraying with the present apparatus. In addition, it is desirable to use a bag filter or the like in order to remove dust more efficiently, instead of using a cyclone as a dust removing device.
