Description

Grass seed sheet {SHEET FOR LAWN SEED}

The present invention relates to a grass seed sheet that is resistant to moisture and maintains its construction state even in rainfall, and also combines manufacturing, handling, and construction safety.

Grass seed sheets, which are widely installed in the natural greenery of the ground where soil loss is concerned due to rainfall, such as incisions, slopes, and cover slopes, are naturally decayed and changed into manure over time as illustrated in FIGS. 1 and 2. The grass seed 3 is sealed in the form of a band or a dot between the upper and lower wrapping papers 1a and 1b or the upper and lower wrapping papers 1a and 1b reinforced with the net 2. Grass seed (3) is a cultured soil (4) to help germination is a placenta combination.

Natural perishable wrappers and nets are mostly natural pulp. In some cases, the upper and lower wrappers are made of foil.

It is particularly weak against moisture and has very low burst strength. Therefore, special care must be taken not to damage the wrapping paper during transportation, handling and construction as well as during the manufacturing process.

However, no matter how careful and careful you handle it, it is very likely that you will lose grass seeds if the packaging is broken or torn.

In addition, the paper wetted by dew or rainwater is easily released after construction and loses strength. The dimly mowed paper is extremely weak in the state of holding the grass seed, which is insufficient to prevent the grass seed from falling down due to the bite and the failure rate of construction is high.

If the grass seed is washed away by the rain or blown away due to the torn wrapping paper, the intended greening purpose will not be achieved.

Conventional foil pavement type grass seed sheet has low practicality because of this disadvantage. Due to the nature of the foil as described above, not only the manufacturing but also the transportation, handling, construction, etc., the whole process is difficult.

It is therefore an object of the present invention to provide a turf seed sheet which is improved in manufacturability, handling, construction and construction stability by increasing the rupture strength of the grass seed sheet made of a paper wrapper and a protective net.

The problem is that a grass seed sheet is packaged together with cultured soil in a strip or dot between the upper and lower wrapping papers, and a protection net is attached to the upper wrapping paper, wherein the bottom surface of the lower wrapping paper is resistant to moisture and has high burst strength. By attaching and reinforcing cardboard, construction stability can be secured so that it can withstand even after heavy rain, and it can be achieved as a sheet for grass seed that can contribute to improvement of manufacturability and handling.

Paperboard is widely used for large and small briefcases, corrugated cardboard, and plain paper packaging for powder or granules, and has a high burst strength and is very resistant to moisture. Yet moisturizing is good.

As these cardboards are attached to the bottom of the lower wrapping paper where the grass seeds are wrapped, the weak papers have been dampened so that even after greening, the grass seeds are swept away by rain and the greening of the grass is concentrated on the lower part of the construction site or the grass seeds are lost. The shortcomings of the grass seed sheet, which were concerned about the achievement of greening purposes, are also eliminated.

In addition, as safety against tearing and rupture of the lower pavement is increased, the manufacturability, handling, and workability of the grass seed sheet are also improved.

3 and 4, the grass seed 3 is packaged together with the culture soil 4 in the form of bands or dots between the upper and lower wrappers 1a and 1b of the paper, and a protective net 2 is attached to the upper wrapper 1a. In the grass seed sheet, the present invention is characterized in that the cardboard (5) is added to the bottom of the lower wrapper (1b).

Carton (5) is very resistant to moisture compared to foil, so strong that it is resistant to moisture and tough enough to be treated even if it is dewy or rainy, so that the packaging capacity for grass seeds persists even after the roots are fully rooted. Say excellent paper.

In addition, the cardboard (5) is advantageous in the case of drought with excellent moisturizing properties compared to the paper, there is also the ability to inhibit the growth or prevent growth of weeds.

Such cardboard is a recycled paper widely used as a large and small yellow paper bag, corrugated paper, yellow paper, and plain paper for packing powder or granules. This recycled paper has a significant comparative advantage over the foil of grass seed sheets.

The grass roots are directional, so after germination they naturally try to reach the ground. At this time, the tough cardboard (5) may be rather an obstacle to the rooting of the grass roots.

In consideration of this point, the root hole 6 is drilled longitudinally and horizontally in the cardboard 5. Root hole (6) after the grass is germinated its roots penetrate the cardboard (5), and the air permeability after root penetration is also secured to contribute to the early lubrication. The root hole 6 is a very small hole perforated with a perforator so that the grass seed 3 cannot escape.

As shown in Figure 5, the sheet for grass seed according to the present invention is sprayed on the grass seed (3) mixed with the culture soil (4) in the form of bands or dots on the lower wrapper (1b), the top wrapping paper (top) on the grass seed (3) Cover with 1a) and bond to lower wrapper 1b.

Subsequently, the protective net 2 is mounted on the upper wrapping paper 1a, and the cardboard 5 is attached to the bottom of the lower wrapping paper 1b. In the illustrated example, the cardboard 5 is shown to be attached over the bottom of the lower wrapper 1b, and according to a simple design change, the spreading width of the cardboard 5 along the spraying direction of the culture soil 4 mixed with the grass seed 3 is changed. It can also be attached on tape as much as it contains.

The cardboard 5 is attached to the bottom of the lower wrapper 1b, and then sprayed with the grass seed 3 mixed with the culture soil 4, the upper wrapper 1a is attached, the protective net 2 is attached, or the lower wrapper ( It is also possible to assume that the procedure proceeds in the order of attaching cardboard (5) to the bottom of 1b), spraying grass seed (3) mixed with culture soil (4), and joining the upper wrapper (1a) attached to the protective net (2) on the upper surface. have.

As the lower pavement supporting the packaged grass seeds is reinforced with tough and moisture-resistant cardboard, the lower pavement is weakly damped so that even after greening, the grass seeds are swept to the side and drove to one side or are lost. Disadvantages of turf seed sheets, which were seriously worrisome for fear of disruption, are expected to be resolved, and manufacturing and handling and construction properties of turf seed sheets are expected to be improved. In addition, the side effects of early sliding of grass caused by weed parasite suppression and breathability are also great.
