Description

TECHNICAL FIELD The present invention relates to a composition for preventing plant growth, and a method for protecting plants from wind,

The present invention relates to a composition for inhibiting the transpiration of plants and a method for protecting plants using the same, and more particularly, to a plant which can prevent damages due to typhoons and winds (wind accompanied by salinity) And a method for protecting plants from wind-induced damage using the same.

Crops are damaged by winds, such as water shortages and typhoons, throughout their growth. In particular, the rice cultivated in farmland near the coast of Korea is suffering from severe wind and sea waters between June and September when typhoons are flooded.

Symptoms caused by winds are leaf blight, inexperienced leaf, white mackerel (unglazed grains), and browning lips. Among these symptoms, whitening and browning formations lead to loss of rice yield and quality deterioration.

The extent to which typhoons damage rice depends on the growth of rice, the level of fertilizer, and the presence of pests and diseases. The largest damage is seen after 3 to 5 days after heading, which is considered to be the result of increased infertility rate, and when the maximum maturity is reached after 17 days of heading, typhoons are reported to be reduced in rice weathering (National Institute of Crop Science, 2004, Government publication no. 11-1390625-000007-01).

On the other hand, techniques for maximizing the conservation of plants by coating the surface of plants include a technique of treating cut flowers as a preservative and a temporary inhibition of plant growth by treating plant hormones such as abscisic acid to suppress the opening and closing of pores And Korean Patent Laid-Open Publication No. 2013-0057811 discloses a method for protecting trees from chloride-based snow removing agents by using arabinose (C ₅ H ₁₀ O ₅ ), galactose (C ₆ H ₁₂ O ₆ ), Glucuronic acid (CH ₂ OH), rhamnose (C ₆ H ₁₂ O ₅ ), and the like have been disclosed.

However, there are no studies on the protection of plants from wind - induced damage by inhibiting the activity of the plants.

As a result of intensive efforts to solve the above problems, the inventors of the present invention have found that when a plant is coated with a plant growth inhibition composition containing a plant oil or a polymer compound having the ability to inhibit the hyperproliferative action of a plant, The present inventors have found that it is possible to prevent the damage caused by typhoons and winds (wind accompanied by salt) by reducing the moisture stress.

It is an object of the present invention to provide a plant growth inhibition composition capable of preventing damage to plants caused by rapid evaporation by high temperature and dry wind.

It is another object of the present invention to provide a method for protecting plants from typhoons and storms.

In order to achieve the above object, the present invention provides a plant inhibiting composition for plant growth comprising a vegetable oil or a polymer compound having the ability to inhibit the hyperproliferative action of a plant.

In the present invention, the vegetable oil is at least one selected from the group consisting of apricot seed oil, olive oil, jojoba oil, linseed oil and soybean oil.

In the present invention, the polymer compound is characterized by being at least one selected from the group consisting of guar gum, PE-635 (paraffin wax 38%, emulsifier 2%, water 60%), liquid paraffin and wax.

In the present invention, the plant transpiration inhibiting composition further comprises an electrodeposition agent.

In the present invention, the plant is an agricultural product selected from the group consisting of crops, fruit, root vegetables, special crops, flower, landscape garden and grass.

The present invention also provides a method for protecting plants from aquatic waters, which comprises treating a plant with a plant growth inhibition inhibitor composition to inhibit the plant's hyperproliferative activity.

In the present invention, the concentration of the vegetable oil or the polymer compound contained in the plant transpiration inhibition composition is 0.01 to 5% by weight.

When the plant growth inhibition composition according to the present invention is used, it is possible to prevent plants from being rapidly evaporated due to typhoons or storm, thereby preventing the loss of the production amount and the quality of agricultural produce.

1 is a schematic view of a cobalt chloride cobalt-based color reaction test for measurement of waterproofing rate (inhibition of vaporization) according to the present invention.
2 is a graph showing the results of suppressing the transpiration effect of the vaporization inhibiting composition treated with corn leaves.

In the present invention, when a vegetation oil-inhibiting composition containing a vegetable oil or a polymer compound having the ability to inhibit the transpiration of a plant is applied to a plant, it is possible to reduce the water stress by temporarily suppressing the vaporizing action caused by the pores of the leaf, To prevent the damage caused by it.

In the present invention, it is predicted that the plant has the ability to inhibit the hyperproliferative action. Examples thereof include polymer compounds such as wax and paraffin; Vegetable oils (or essential oils); The electrodeposition agent and the surfactant were selected and the waterproofing rate and the inhibitory effect of the plant on the evaporation of cobalt chloride were investigated. As a result, it was confirmed that the vegetable oil or the polymer compound is excellent in the waterproofing ratio due to the reaction of generation of cobalt chloride and temporarily inhibits the outflow of water from the plant by the action of the vaporization.

Accordingly, the present invention relates, in one aspect, to a plant inhibiting composition for the inhibition of plant growth, comprising a vegetable oil or a polymer compound having the ability to inhibit the hyperproliferative action of a plant.

The vegetable oil is selected from the group consisting of apricot seed oil, olive oil, hohoba oil, linseed oil and soybean oil. Or more.

The polymer compound may be at least one selected from the group consisting of guargum, PE-635 (paraffin wax 38%, emulsifier 2%, water 60%), liquid paraffin and beeswax do.

The formulation of the plant growth inhibition inhibitor composition can be used without any particular limitation, such as an oil agent containing a vegetable oil or a polymer compound, a wetting agent, a liquid wettable powder, a granular wettable powder, a liquid agent, It is preferable to be emulsion.

In the present invention, the plant is not particularly limited, but it is preferably agricultural produce. Examples of agricultural produce include crops, fruit, root vegetables, special crops, flower, landscape garden, grass and the like. Particularly, rice is more preferable as a target plant because it is vulnerable to damage by evaporation when a strong, high-temperature drying wind such as a typhoon occurs.

The vegetable oil or the polymer compound constituting the composition for inhibiting the transpiration of the plant exhibits a somewhat different effect of inhibiting the evaporation depending on the inherent evaporation mechanism of the plant or the nature of the physiological regulation mechanism of water in the body, do.

Meanwhile, in the present invention, it was predicted that the use of an electrodeposition agent together with the vegetable oil or the polymer compound could enhance the ability of plants to inhibit the hyperproliferative action.

In another embodiment of the present invention, the rice was treated with a mixture of an electrodeposited film (Neuss membrane, silhouette, eastern cover) and soybean oil. As a result, it was confirmed that the effect of inhibiting the rate of transpiration was enhanced when a combination of an electrodepositive agent and soybean oil was used, compared to when soybean oil alone was treated.

Therefore, the plant transpiration inhibiting composition is characterized by further comprising an electrodeposition agent. The electrodeposition agent allows the vegetable oil or the polymer compound to adhere well to the plant, and a commonly used electrodeposit agent can be used without particular limitation if it spreads evenly.

The concentration of the electrodeposition agent is not particularly limited, but it is preferably contained in the composition at a concentration of 0.01 to 5 wt% in order to improve the potency of the plant to suppress the transpiration effect more effectively.

In another aspect, the present invention relates to a method for protecting plants from aquatic waters, which comprises treating plants with the composition for inhibiting the transpiration of plants, thereby inhibiting the plant's evaporation.

In the present invention, the vegetation-inhibiting composition for plants to be treated with a plant preferably contains a vegetable oil or a polymer compound in a concentration of 0.01 to 5% by weight. If the concentration is less than 0.01% by weight or exceeds 5% by weight, the effect of inhibiting the evaporation may be low, or the concentration may be weak.

That is, when the plant growth inhibition composition according to the present invention is sprayed on the plant 1 to 2 days before the blowing of the high-temperature high-temperature dry wind, a thin coating film is formed on the surface of the leaf or the conductor to suppress the rapid- , It is effective to prevent the leaf from being frayed or the seed to be non-fused, and to maintain the physiological function normally.
