Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a plant growth regulator comprising an aqueous solution of wax and a method for producing the same.

More specifically, the present invention relates to an aqueous plant growth regulator containing wax dispersed in water as fine particles so that it looks like a clear solution in appearance, and a method for producing the same.

Additionally, the present invention, by its nature, encompasses the use of the above-mentioned growth regulators.

An object of the present invention is to provide a drug that can regulate the growth of plants without adversely affecting them.

According to the present invention, plant wilt is prevented, vigor is maintained,
The survival rate at the time of transplantation can be increased, and growth can be accelerated by temporarily suppressing growth and subsequently enhancing it. In addition, another object of the present invention is to produce grains,
The purpose is to increase the harvest of fruits, greens, etc.

The outline of the present invention is to provide a plant growth regulator comprising an aqueous solution of a homogeneous mixture of wax and a surfactant capable of solubilizing the wax, and a plant growth regulator obtained by blending the wax and the surfactant capable of solubilizing the wax. This is a method for producing a plant growth regulator characterized by dissolving a homogeneous mixture in water.

The wax used in the present invention may be of mineral, vegetable or animal origin.

As the mineral wax, for example, petroleum wax or mosotan wax can be used.

Petroleum wax includes paraffin wax and microwax. Examples of vegetable waxes include carnauba wax and cotton wax.

Examples of animal waxes include beeswax and spermaceti.

It is generally preferable for the wax to have a higher melting point.

Waxes with melting points of 60° C. to 120 qo are often used.

These may be used alone or in combination of two or more as necessary.

The surfactant capable of solubilizing the wax used in the present invention is one that has compatibility with the wax to be blended, forms a homogeneous liquid when separated from the wax, and mixes the molten liquid with water. Sometimes those that are soluble in water are selected.

It can be screened by a simple preliminary test of mixing wax and surfactant and then mixing with water.
Such surfactants can be ionic or nonionic.

As the ionic surfactant, for example, an organic base salt of an acid having a higher lipophilic group such as an acidic sulfate ester of a higher fatty acid or a higher alcohol is preferably used.

Examples of the above-mentioned higher fatty acids include lauric acid, myristic acid, stearic acid, palmitic acid, oleic acid,
Examples include linoleic acid and linolenic acid, and examples of higher alcohols that form acidic sulfate esters include cetyl alcohol, oleyl alcohol, myristyl alcohol, lauryl alcohol, decyl alcohol, and octyl alcohol.

The number of carbon atoms in the lipophilic group of higher fatty acids and higher alcohols is generally preferably in the range of 15. However, when the organic base described below has a large number of carbon atoms, the number of carbon atoms may be slightly smaller than the above. The organic base to form a salt with these acids can be selected as appropriate as long as the purpose of the present invention can be achieved.
Considering toxicity, aliphatic amines are preferable to aromatic amines, such as mono(
Examples include di- or tri-)methyl (or ethyl) amine, ethylenediamine, cyclohexylamine, mono-(di- or tri)ethanolamine, and morpholine.

These are all examples that are easy to obtain. Amines with a larger number of carbon atoms can also be used if necessary. A salt is easily formed by bringing the above acid and base into contact in a suitable solvent, and the salt is separated by removing the solvent.
In the case of morpholine and the like, a salt can generally be formed by mixing it with an acid.

Nonionic surfactants are generally eg polyhydric alcohols.
or its partial anhydride, higher fatty acid esters, and polyoxyalkylene ethers of higher aliphatic monohydric alcohols.

Examples of the polyhydric alcohol include ethylene glycol, diethylene glycol, propylene glycol, glycerin, sucrose, sorbitol, and polyethylene glycol, and examples of its partial anhydride include sorbitan. Preferred examples of the nonionic surfactant include higher fatty acid esters of diethylene glycol, higher fatty acid esters of sorbitan, and polyoxyethylene ethers of higher aliphatic alcohols.

The amount of surfactant to be used depends on the type of wax and surfactant, but generally a fraction to several times the amount of wax is sufficient.

The plant growth regulator of the present invention is produced by melt-mixing a wax and a surfactant under heating if necessary, and then mixing and dissolving the resulting homogeneous mixture in water.

Miscibility with water is generally easier and gives better results with hot K. The growth regulator of the present invention is applied in the form of a dilute aqueous solution to the outer surface of the plant, avoiding the bran as much as possible, by applying operations such as spraying, misting, coating, and soaking.

Of course, depending on the purpose, it may be applied to local parts of the plant, such as the underside of leaves or fruits. The concentration of wax in the dilute aqueous solution is preferably about 0.6-5%. If it is thinner than this, it will have little effect, and if it is thicker than this, it will likely cause local damage to the plants. The timing of applying the growth regulator of the present invention to plants is as follows:
The young leaf stage after germination, before and after transplanting, and before flowering are preferred.
It may be applied at other times as needed. By applying the growth regulator of the present invention, the transpiration effect of plants is generally suppressed for about 10 days after application, and the transpiration effect remains active for 10 days or more thereafter, and the assimilation and respiration effects are reduced by 150%.
It shows a tendency to increase by ~200%. Although the reason for this is unknown, an extremely thin wax film (0.05 to 0.0
．． 2 microns or less). Therefore, it is generally desirable to apply the growth regulator of the present invention at intervals of about 20 days or more. By applying the growth regulator of the present invention, plant growth is promoted, flowering, fruiting, and harvest time are earlier, yields are increased, survival rate at the time of transplanting is dramatically improved, and summer withering and frost damage are prevented. Can be done.

Particularly, when the growth regulator of the present invention is applied to plants of the Phytaceae family, such as rice, the increase in plant height and plant weight is remarkable, and the increase in heading and
The period between flowering, fruiting, and harvesting is shortened, and the yield is 1-2.
increase by a percentage or more. As mentioned above, when the growth regulator of the present invention is applied to plants, transpiration, respiration and assimilation are significantly increased, and as a result, nutrients are accumulated significantly during fruiting, and the fruit becomes enlarged. , good fruits can be harvested early, and in the case of rice, for example, it is thought to result in a significant reduction in the amount of spores, an increase in effective tillering, and an increase in yield.

Particularly in rice cultivation in cold regions, by using the growth regulator of the present invention to advance the flowering period by at least 2 to 3 days, the harvest period can be accelerated and the undesirable effects of cold air in autumn can be avoided.

Furthermore, in the case of cuttings of cedar, cypress, etc., in the usual cultivation method, the cutting bed is covered with sun cover, but if the growth regulator of the present invention is used, there is no need for sun cover, which saves time and effort.

In addition, since there is no sun cover, carbon assimilation on the leaf surface of cuttings begins immediately after cutting, so the time required for rooting is shortened, rooting is improved, and healthy plants are easily obtained. In addition, in the case of fixed value of seedlings, since the seedlings treated with the growth regulator of the present invention do not wilt, the fixed value can be prepared the day before, which is advantageous when dealing with a large number of seedlings. Furthermore, if the growth regulator of the present invention is applied to citrus fruits on the tree without picking them, the period during which the fruits can be left on the tree will be extended while preventing the fruits from wilting or losing weight.

This is effective, for example, when growing mandarin oranges on a tree over the years, and has the advantage of spreading the labor required for fruit harvesting over a long period of time. Examples of the present invention are shown below, but the present invention is not limited to these examples.
