Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a turfgrass cell division / growth promoting material which activates renewal of turfgrass used for lawn.

[0002]

2. Description of the Related Art A lawn is a plant that needs to be constantly renewed and grown because a person rides on it and is stepped on it, is pruned low, and is a perennial plant. Lawn managers use machines to make holes in the soil, scratch them, and make cuts to aerate the soil to maintain and improve the activity of turfgrass. In order to spray an activator such as, or to create a soil layer where turf grass grows,
Sprinkle with soil.

[0003] In addition, it is common to use sand for the soil and floor soil of lawn to prevent the soil from solidifying.
It is an optimal material for maintaining good water permeability and air permeability of soil, but on the other hand, fertilizer nutrients and water loss are severe.
It has drawbacks such as low soil microorganisms and lack of soluble minerals, and it can be said that the soil has the soil's fertility.
As the soil was being renewed, it had almost no significant turf grass regeneration capacity. The above-mentioned fertilizers and activators are sprayed from the surface to compensate for the lack of regeneration power, but as mentioned above, it can be said that it is effectively exerting an effect on turfgrass due to severe runoff. It wasn't the case.

On the other hand, the applicant of the present invention has proposed, as a bed soil for raising seedlings of rice, Japanese Patent No. 1285578 (Japanese Patent Publication No. 59-44011) based on granulated slag produced as a by-product from a cupola furnace.
No.) as a soil for cultivating gravel for gardening, Japanese Patent No. 145872
No. 0 (Japanese Examined Patent Publication No. 63-3566) was previously announced, but these were inventions used as floor soil for rice and gardening.

[0005]

The regeneration ability of turfgrass is the ability to improve the cell division and proliferation of turfgrass, and experiments were repeated and studied for the purpose of solving the problem of this shortage. The present invention was completed based on the finding that granulated slag, which is a by-product, has the ability to regenerate turfgrass, that is, the ability to improve division and proliferation of turfgrass cells. That is,
An object of the present invention is to provide on the market a material for promoting cell division / growth of turfgrass, which is important for renewal of turfgrass and which improves the regeneration ability of turfgrass.

[0006]

The present invention is a granulated slag that is produced as a by-product from a cupola furnace during the production of cast iron, and is characterized in that the content R of CaO / SiO ₂ is R ≦ 1. It is used as a material for promoting cell division and growth of turfgrass. The chemical composition of granulated slag by-produced from this cupola furnace is as shown in Table 1, and the chemical analysis based on the Fertilizer Control Law is shown in Table 2.
The characteristic is that the component gradually elutes little by little over a long period of time.

EXAMPLES The present invention will be specifically described below with reference to examples. Example 1 In bento turf green (about 500 m ² ) at a golf course in the suburbs of Tokyo, a zone in which 800 g / m ² of the present invention was sprayed from the surface in the middle of March and a non-scattering zone were provided, and the beginning of September (scattering) Six months after), the soil with turf was extracted from both plots, and the turf thickness was cut to 2 cm below the surface of the earth. Regenerative power of (turf grass cell division,
In order to investigate (proliferation ability), the plant was installed in a pot and the growth condition by fresh water cultivation for 46 days was investigated. In addition, in order to check the result of fresh water cultivation, in mid-October (approx.
In the first month, we investigated the growth situation at the golf course.

As a result, in the fresh water cultivation of the picked product, the roots grew more than twice in the spraying area, and 46 times after the start.
On the day, the roots of the non-dispersed plots were brownish and stopped growing, but the roots of the sprayed plots were white and continued to grow. Regarding the leaf color, the green color was slightly darker on the 22nd day after the start of the application, but on the 46th day after the start of the application, the application color of the leaf became lighter, and the turfgrass cell division / proliferation was caused by the nutrients of the present invention by the present invention. It has been found that it is effectively used for The growth rate at the golf course is 45% in the scattered area compared to the non-dispersed area.
The result was similar to that of fresh water cultivation at the golf course.

Example 2 At a lawn cultivating field (bent turf nursery) of a golf course in Chiba prefecture, the product of the present invention was mixed with 20% of soil and 10
% Soil mixed zone and non-mixed zone (20m ^{2 for} each zone) are set up, and two grass soils are collected from each grass for 18 months after planting bent grass, and the turf thickness is below the surface. 2c
In order to investigate the regeneration ability of turfgrass (cell division / proliferation ability of turfgrass), which is cut by m and grown only by the nutrients in the turf body accumulated up to that point and the remaining nutrients in turf in the field, It was placed in a pot and the growth status of fresh water cultivation for 76 days was investigated.

[0013] As a result, in the non-mixed group, almost no stalks were found, whereas in the mixed section, the growth of the stalks (runners), which is the growth function of bent grass, was strong, and the growth stage was advanced. The growth rate was 37% in the 20% mixed group and 41% higher in the 10% mixed group than in the non-mixed group. Regarding the leaf color, on the 76th day after the start, the mixed color of the leaf color became pale as in Example 1, and the nutrients in the turf were efficiently utilized for cell division and proliferation of turfgrass by the present invention. Was found.

Example 3 As with the golf course green, in order to examine the regeneration power of bent grass (cell division / proliferation power of grass grass) under control, the pot of the present invention was mixed with a pot soil (two consecutive tests). Control, that is, using 2 pots common to each ward) was carried out, and the change with time of the surface coverage of turfgrass and the number of leaves per pot at the end (4th month) were investigated. The section is a 20% mixed section, a 10% mixed section, a non-mixed section as a control and a zeolite (hard) 20% mixed section, and the unmixed section is a soil of 80% sand and 20% beet moss (volume ratio). In the plot, each test material was mixed in each% in the soil, and 7.5 g of the chemical fertilizer (N8, P12, K8) was simultaneously mixed as a base fertilizer per pot, and the bentgrass cut into a diameter of 1.5 cm were planted. The test period was from the beginning of July to the beginning of November, during which the cutting height was always 1 cm, and the foliage protruding from the outer diameter of the pot was cut at the same time. In addition, additional fertilization was carried out once a month after the start of fertilization with 100-fold solution of Hyponex (N5, P10, K5) 100 times in each pot. Further, in the end of September, 1 mm thick sand in each pot was applied. (Pot capacity 1 liter, inner diameter 11.
5 cm, depth 9.5 cm, outer diameter 15 cm)

As a result, as shown in Table 3, the surface coverage of the mixed section spread faster and improved. Regarding the number (density) of turfgrass leaves at the 4th month, the mixed plot had a larger number of leaves than the non-mixed plot and the zeolite plot, and many thin leaves were growing. This result is a result of growing in an area of a pot having an outer diameter of 15 cm, and the fact that the surface coverage was improved and the number of leaves was increased by the present invention was due to the strong regenerating ability of bent grass and the limitation. This is the result of repeated vigorous cell division and proliferation within the given area.

[0003] In addition, it is common to use sand for the soil and floor soil of lawns to prevent the soil from solidifying, and in order to maintain good water permeability and air permeability of the soil. Sand is the most suitable material, but on the other hand, it has drawbacks such as severe loss of fertilizer nutrients and water, less soil microorganisms, and lack of soluble minerals. As a result, the soil is in a state where there is almost no regeneration of important turfgrass. The above-mentioned fertilizers and activators are sprayed from the surface to compensate for the lack of regeneration power, but as mentioned above, it can be said that it is effectively exerting an effect on turfgrass due to severe runoff.
