Conventional seeding for seed germination of crops, which may be said to be the first step in the cultivation of crops, is a primitive method in which a person directly sows in soil using a machine or a machine, and the nutrients of the crops Have been supplied with fertilizers and nutrients or sprayed with herbicides to remove weeds.

In addition, since the conventional seeding method, especially direct seeding method in which rice seed is directly sown on the cultivated land such as rice paddies, does not provide the optimal environment for germinating the seed, the germination rate of the seed is low, Because it is difficult to work, it requires a lot of manpower. Therefore, it is difficult to plant seeds in large quantities at once. It is uneconomical and inefficient. In order to remove weeds, it is necessary to spray herbicide or remove weeds every time. Therefore, it is difficult to control weeds by manpower. There is a problem in growth such as exposure to tidal water and exposure to unevenness in planting distance,

Especially, in the rural realities where the labor shortage due to aging and the decline of agricultural labor force is deepening, the technology of simplifying seeding for coping with the shortage of manpower and the technology for creating the optimum environment for germinating seeds It is possible to reduce the labor and cost of seeding by facilitating sowing of seeds and to increase the germination rate of seeds, so that it is possible to avoid the inconvenience of additional sowing and to prevent the propagation of weeds and pests.

[0005] In order to solve the above-described problems of the seeding of the prior art, various technologies such as a seed sheet or a seed tape have been developed.

Conventional techniques are mere functional seeding sheets having seeds only between substrates such as non-woven fabric, such as a non-woven fabric, which is required to be completely decomposed within the growing period, although it exhibits a mulching effect so that a plurality of seeds can be planted at one time. Such as a seeding sheet coated with either a fertilizer, a nutrient or a herbicide necessary for growth of the seed, a nonwoven fabric in which the release of the active ingredient such as fertilizer is not controlled or a seed or a fertilizer is received in a natural state It can not be decomposed and it needs to separate collection work after use or pollution of soil and water quality. So it is necessary to simplify sowing so that a large number of seeds can be sowed at once, and release it uniformly at an appropriate time so as to promote germination Of multi-functional seeding sheets This was not a problem.

SUMMARY OF THE INVENTION Accordingly, the present inventors have made efforts to solve the above problems of the conventional art,

It is difficult to properly supply fertilizer, nutrients, and herbicides required for growth of crops within the cultivation period of crops in a suitable period of time, so that the crops do not grow properly and are not decomposed to cause secondary pollution, Function By replacing seeding sheets with simple-function seeds that sow seeds in general-purpose vinyl mulch materials or crops,

It is decomposed in the natural state, it does not need separate collection work, there is no pollution of soil and water quality, and it is possible to plant a number of uniform seeds at once even if it is laid on the desired seeding place conveniently. The present invention relates to a method for seeding direct-seeding of seeds according to the present invention, which enables seeding with additional fertilizers and nutrients and manufacturing agents per growth stage required by crops, simplifying planting and promoting germination uniformly at a proper elution rate Friendly multi-function seeding sheet.

As described above, the seeding sheet of the prior art has various technical problems,

In the present invention, it is possible to replace the seeding sheet with the seed of the simple function that sows the seed of the general purpose vinyl mulching material or the crop,

Eco-friendly multi-functional seeding sheet All.

In the eco-friendly multi-functional seeding sheet 100 for seeded direct wave according to the present invention, the multi-functional biodegradable sheet 100 may be prepared by mixing porous biodegradable Korean paper with PLA (polylactic acid, PLA) A porous, breathable biodegradable sheet obtained by mixing and kneading together octane and biotite as a nonwoven fabric,

It is biodegradable after a certain period of time. It does not cause environmental pollution due to disposal. It has not only antibacterial ability but also has excellent water absorption and maintenance ability. It has advantages of environmentally friendly PLA (polylactic acid, PLA) Duck pulp, a Korean paper-based duck pulp which has good cushioning properties, warmth and hygroscopicity but weak in water and easy to tear, has a growth effect, but it is difficult to solidify the properties basically. When it is dry, it hardly cracks and easily decomposes in water.

In particular, the composite-function seeding sheet of the present invention is improved in physical strength, mechanical strength, and physical properties of an active active ingredient by compressing and piling each constituent component into a single sheet, which is conventionally heat resistant and is widely regarded as a biodegradable natural material of a low- However, PLA resin having disadvantages of being decomposed into moisture, dough pulp, loess, biotite powder and other functional materials can not be obtained by the functional sheet of the composition alone or simply mixed. By supplementing weak durability and water resistance, which is a fatal weak point, it is not completely decomposed at the early stage of crop growth but gradually degraded to the harvesting stage. Thus, the coating effect of the seed or medicament covering layer is maintained, And also functions as an insulating cover The yellow earth and milling the okbun, biotite minutes and the pulp is shut be a far infrared ray radiation surface area acting on the seed increases, since the integrated mixing equator far-infrared radiation efficiency is maximized

The PLA (polylactic acid, PLA) resin as the main material of the environmentally-friendly, multi-functional seeding sheet 100 for seeded direct wave according to the present invention is prepared by polymerizing lactic acid produced by the fermentation of polylactic acid, Because it is a thermoplastic material with biodegradable properties, it can be completely biodegraded by water, carbon dioxide or water and methane gas by natural microorganisms such as bacteria, algae and fungi, As the main raw material.

The addition of duck pulp as an additive material as a feedstock of the multifunctional seeding sheet described above is characterized by a long, soft, strong tensile force and excellent fiber characteristics, and the matt bark bark fiber material has high viscosity and strong cohesion, It is equipped with both loess and far-infrared radiation functional mineral as well as biotite and fine powder to reinforce bonding force between grains, so that there is no drying shrinkage, cracking and peeling phenomenon, and it is natural, aesthetic, soft, soft, The multi-functional sowing sheet with improved water resistance and durability is formed. The nails and biotite contents added to the sheet are filled with gaps and gaps between the respective constituent materials to improve the physical properties such as density and whiteness of the functional sheet. Acts as a binding agent It is good.

As is well known, far-infrared rays have been proved by modern science, and many products around life have been developed and released by using high-efficiency far-infrared radiation material existing in nature in the past, such as loess, oak, elvan, and germanium biotite In addition, various uses are being discovered.

Hwangto is a living organism called loess because it emits a large amount of far infrared ray which is essential for the growth of plants. It is reported that plants irradiated with far infrared ray have a good germination power and can cultivate properties.

Jade, which contains a large amount of beneficial minerals such as calcium, iron, and magnesium, has a beneficial effect on the human body and crops because of the radiant energy of the far-

The detoxifying germanium biotite is composed of germanium. It emits a large amount of far infrared rays, acts as an antibacterial, antifungal, antifungal and noxious gas adsorbent, emits a large amount of anion, activates water molecules and promotes growth. Results It has been found that germanium acts as an oxygen catalyst to assist in the efficient utilization of oxygen.

In the present invention, the functional material may be selected from a variety of equivalents of physical properties that emit far-infrared rays and anions, and may be mixed with one or more.

The rosin emits a fragrance and has a property (tensile force) that strengthens paper as a sizing material. Therefore, it plays a role of strengthening the strength of the paper by strongly forming a coating of paper of weak resistance to moisture after drying, The reason why the particle size of the biotite and biotite is 320 mesh or more is because when the particle size is 320 mesh or less, the particle size is large and the adhesion is weak.

The functional sheet constituting the multifunctional seeding sheet of the present invention is a natural substance component and is decomposed naturally without being collected separately after harvesting. Thus, the functional sheet is converted into an organic material, thereby preventing the acidification of the soil, and the higher the temperature of the solar heat, As the temperature increases due to the heat applied, the effect of germanium in the soil promotes the growth of the crops.
