Abstract

PROBLEM TO BE SOLVED: To provide a construction method for planting seedlings of ground covering plants, enabling to perform greening with ground covering plants replacing turf at a lower cost a similar construction cost to that for turf sodding than that for the conventional planting potted seedlings method. SOLUTION: The construction method for the planting seedlings of the ground covering plants saves a greening cost by using inexpensive cell-molded seedlings (molded seedlings) having nearly the middle-finger size, instead of using potted seedlings, and taking inexpensive and easy broadcast seedling and surface compaction instead of the conventional planting method for greening, wherein the surface compaction means a plating, which comprises vertically scattering root balls and burying them into soil by the loads of a roller.

Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for greening a place, such as a riverbed, a park, or a green belt, which was previously greened by lawns, using a ground cover plant. [0002] Conventionally, revegetation of riverbeds and the like has been performed mainly by sticking lawns. However, a lawn plant becomes robust only after human management such as lawn mowing. [0003] The current state of the management work on riverbeds and the like is that the management work is never satisfactory, such as lawn mowing about 1 to 3 times a year and fertilization about 1 to 2 times. In a few years, it will be an original wasteland covered with weeds. In addition, since burning in the field has been prohibited in recent years due to the problem of global warming and the like, the current situation is that it is troublesome to dispose of cut grass generated by lawn mowing. [0004] As an alternative to lawns having such a problem, it is conceivable to use plants called ground cover plants, such as Himeiwadaresou and sedum. This plant has the following characteristics: cutting is not required, cutting grass does not need to be disposed of during cutting, it requires only a small amount of fertilization, and it has a weed suppression effect that is not found in lawns, reducing the need for weeding. The vegetation can be maintained with extremely labor-saving management work. Also,
There are many types that are rich in dry resistance, heat resistance, cold resistance and disease resistance, and the coating speed is extremely fast. [0005] Why is there no large-scale utilization? There are other reasons such as resistance to treading, but this can be solved by using a type that is strong against treading, such as Himewadareso. The biggest reason for no large-scale utilization is cost. When planting pot seedlings of ground cover plants at a general rate, [Fig. 1]
As shown in the table above, there is a problem 1 that a difference in money amount is at least twice or more with respect to the pasting of the lawn. In addition, products grown in a mat shape are also sold, but when the products are used, the difference in the amount of money becomes more remarkable. [0006] In order to solve the problem 1 (to reduce the cost), it is considered to apply the technology in the agricultural field to the greening business. [0007] First, the seedlings are changed from expensive pot seedlings to extremely inexpensive middle finger-sized cell molded seedlings (named mold seedlings in the present invention to differentiate the quality of seedlings) [Fig. Pot 448 (14 rows x 32 columns = 448 holes) from Minoru Sangyo Co., Ltd. (Fig. 2), or pot 324 (12 rows x 27 columns) in a nursery tray for growing cell molded seedlings (mold seedlings) = 324 holes). [0008] In addition, the construction method is reduced from the conventional planting [Fig. 1m ²
The amount of cell molded seedlings (mold seedlings) used per unit is set at about 30 to 70 seedlings / m ² in accordance with the required covering period. [0009] The construction is very simple, as shown in [Fig. 4], the soil is softened by tilling, etc., and after leveling the soil, a predetermined amount of cell seedlings (mold seedlings) are scattered and pressed by rollers to complete. It becomes. The meaning of the roller compaction performed here is the act of embedding the root pots of seedlings scattered sideways into the soil with the load of the roller, in the sense of planting in a usual manner. When a planting test was actually carried out using lateral compaction, it showed growth that was no different from normal planting. As a method similar to the present construction method, a method by spraying is currently practiced, but the cost is not much different from the conventional planting due to materials to be mixed, spraying of soil, damage to a spraying machine, and the like. It is an expensive construction method. The reference design prices of this method are shown in the table of FIG. Embodiments of the present invention will be described below with reference to contents to be constructed. There are six kinds of cell-molded seedlings (mold seedlings) to be produced: Himewadareso, Ibuki-kusou-so, Mexico Mangusa, Tsurumanengusa, Matsubagiku, and Hanazurusou. [0015] The production method is a seedling raising tray (pot 324).
, And fill with a special soil for buds, and insert a bud of a ground cover plant with at least one node straight into the center of the hole to bud.
It takes about 30 to 50 days for the seedlings to grow into usable seedlings, and is irrigated twice in the morning and evening to promote rooting and growth. Immediately before shipment, in order to prevent troubles caused by root mortar collapse at the time of seedling extraction or roller compaction, a cell molding seedling (mold seedling) is used using a root mortar solidifying agent (such as TB-1 of Minoru Sangyo Co., Ltd.). The root mortar is solidified, packed in a special cardboard box and transported to the construction site. [0017] at the construction site, stripped in advance lush weeds present situation soil in 15cm thick, also leveled laid in 15cm thickness of the decomposed granite soil was purchased, 5kg / m 2 cow dung active compost Fumiraipu A as ^basal, slow-release fertilizer Mag amp K (N
6-P40-K6-Mg15) at a rate of 50 g / m ² and leveling. The cell molded seedlings (mold seedlings) arriving at the construction site are withdrawn from the seedling raising tray and distributed at a rate of 54 seedlings / m ² . The composition ratio of the seedlings to be scattered is set to 1: 1 (9 seedlings / m ² because there are six types in this construction). Then, rolling is performed with a roller, and when it is confirmed that the root pot of the seedling is sufficiently embedded in the soil, planting is completed. After the completion of planting, the slow-release fertilizer high-control 100-day type (N10-P1
8-K15) is sprayed on the surface at a rate of 50 g / m ² . During the initial growth period, irrigation is particularly emphasized, and 100
Appropriate irrigation and manual weeding of large weeds are performed until vegetation with% coverage is obtained. Although it depends on the construction time and the amount of seedling used,
In about 3 to 4 months, a 100% covered ground cover plant is completed. It requires much less labor to manage than lawns, and generally has a long flowering season, so it has an excellent landscape and is used for a long time as a place for local residents to relax. As described above, according to the present invention,
Industrially useful ground cover plants can be effectively used for greening projects. Since the material can be made extremely inexpensive and the work effort can be reduced, the cost can be greatly reduced, and this is the cheapest greening method using ground cover plants instead of lawns. As a result, it is thought that the greening of the labor-saving management with the excellent landscape can be spread nationwide by the Grand Cover Plants, and the contribution to society can be greatly contributed to, such as reduction of management costs and prevention of global warming by suppressing the occurrence of cutting grass.

Claims (1)

Claims 1. Unlike a lawn, a ground cover plant that can maintain vegetation with labor-saving management work. However, planting has traditionally been done by planting expensive pot seedlings,
The problem that the cost is higher than that of lawn has arisen, and its use on a large area has been shunned, despite being an industrially useful plant. Therefore, a ground cover plant seeding method is proposed below as an extremely inexpensive alternative to the conventional pot seedling planting. In this method, instead of pot seedlings,
Use extremely inexpensive middle finger-sized cell molded seedlings (mold seedlings) to reduce costs. In addition, the cost of construction is reduced from conventional planting to inexpensive and simple distribution and compaction. The procedure is as follows: first, the soil is softened by tilling, etc., and the ground is leveled. Then, a predetermined amount (about 30 to 70 seedlings / m ² ) of cell seedlings (mold seedlings) are scattered, and the compaction is performed using a roller. The planting is completed when it is confirmed that the root pot of the seedling is sufficiently embedded in the soil. The meaning of the compaction performed here is the act of embedding the root pots of seedlings scattered sideways into the soil with the load of a roller, in the sense of planting as usual.
