BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for growing agricultural products, which comprises mixing a leaf surface absorption nutrient and an insect repellent.

[0002]

2. Description of the Related Art Conventionally, inorganic fertilizers containing nitrogen, phosphoric acid, potassium, etc. as main components are administered to soil to absorb nutrients from the roots of plants and combine them with carbohydrates which are carbon sources produced in the plant body. However, the long-term administration of inorganic fertilizers has caused acidification of the soil, which causes problems such as diseases of crops and a decrease in crop yield.

On the other hand, in recent years, it has been found that plants also absorb nutrients from the leaves, and foliar sprays have been developed which absorb nutrients from the leaves, most of which are water. It was a method of dissolving it in and spraying it with a sprayer. This is very labor intensive and the spreader is expensive and not easily available for purchase.

Therefore, the applicant of the present invention filed Japanese Utility Model Application No. 4-2987.
In No. 51, a method for growing agricultural products using a sublimable foliar absorption nutrient that can increase yield and greatly improve profitability by a low cost and simple method was disclosed.

[0005]

However, the foliar-absorption nutrients used in the above-described method for growing agricultural products are merely nutrients, and pest control indispensable for growing agricultural products is conventionally controlled by insect repellents and insecticides. It was necessary to spray a chemical solution such as a germicide.

That is, in terms of spraying the pest-controlling chemical with the chemical spraying machine, it has been unavoidable that both the cost reduction and the labor reduction are insufficient.

An object of the present invention is to provide a method for growing agricultural products which can solve the above problems.

[0008]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

(Embodiment 1) In FIG. 1, 1 is a vinyl greenhouse for agriculture, which has an area of about 600 m ² . The vinyl house 1 here also includes a greenhouse consisting of a glass chamber.

Numeral 2 is a cucumber seedling as an agricultural crop cultivated in the vinyl house 1.

In the method for growing agricultural products according to the present embodiment, the labor of spraying fertilizers and insecticides with a chemical solution is greatly reduced, and
In order to increase the yield of cucumber 2 without the need to purchase a chemical sprayer, etc., a leaf surface absorption nutrient having sublimability and an insect repellent are mixed or mixed to form a growth agent 3. , The same growth agent 3 is housed in a container, and the same container is hung or placed in the vinyl house 1 to vaporize and diffuse the growth agent 3 into the air, and from the leaf surface of the cucumber seedling 2. The nutrients are absorbed and pests and the like in the vinyl house 1 are simultaneously exterminated.

The growing agent 3 used in the present invention is prepared by mixing or mixing a leaf surface absorption nutrient and an insect repellent. As the leaf surface absorption nutrient, ammonium carbonate having sublimability, Ammonium bicarbonate, ammonium acetate and urea are preferable, and as the insect repellent, parachlorobenzene, camphor, and naphthalene, which also have subliming properties, are preferable, and they also have a bactericidal effect of pathogenic bacteria which are harmful to crops.

Most of the above leaf surface absorbing nutrients and insect repellents sublime at room temperature, so if suspended or placed inside a vinyl house 1 for growing agricultural products such as cucumber 2, The powdery solid is gradually sublimated to diffuse the nutrient and insect repellent components into the air.

The components of such nutrients are taken into the body directly from the leaves of the cucumber seedlings 2 and act as nutrients, and the insect repellents can also exterminate and sterilize harmful insects such as aphids and sea flies. . In particular, there is an effect that aphids lurking on the back surface of leaves can be easily removed.

Further, since each leaf surface absorption nutrient and insect repellent do not have a bad influence on the human body, there is no problem even if it is used for growing agricultural products in the vinyl house 1, and it can be safely used.

As described above, in the method for growing agricultural products according to the present invention, since the nutrient and the insect repellent are diffused in the air, no special equipment or management is required. It is possible to promote the growth of agricultural products by simple operations such as replenishment of crops and significantly improve the yield.

In the foliar absorption nutrient, urea has a sublimation temperature higher than room temperature, so it is necessary to continuously heat it to accelerate sublimation.
