2. Description of the Related Art Environmental factors that influence the growth and development of sugar beet crops are classified into three major groups: climatic environment, soil environment, and biological environment. The climatic environment is related to light, temperature, moisture, and air, and the soil environment is
It is related to the environment created by roots and plant tissue in the soil. Biological environment means the environment that results from the use of sugar beet crops by humans, cultivation management work, and relationships with other organisms. For the growth of sugar beet crops, it is necessary to consider each of the above-mentioned environments, and it should be noted that each environment does not act individually but interacts with each other to affect the growth of crops. I won't.

Vegetable crops, together with their surrounding environment, make up the soil ecosystem. Among them, soil is a base on which plants grow, and its properties are closely related to plant growth. Therefore, a good understanding of soil is required to control crop cultivation. To this end, soil surveys must be conducted to analyze the physical, chemical, and biological properties of the soil to ascertain the appropriate environmental conditions for crop cultivation.

Soil conditioners are substances used to improve the physical and chemical properties of the soil so that the soil conditions are adapted to the growth of the crop in order to increase the yield of the crop. In particular, since most of the Korean soil is an agricultural land that exhibits acidity, alkaline substances that weaken or neutralize acidity (for example, lime and silicic acid) are mainly used as soil conditioners.

On the other hand, olivine is a hydrated silicate having a hardness of 2.5 to 4 and contains an extremely large amount of magnesium, and in addition to magnesium, it is absolutely necessary for soil such as iron and silicon. It is a mineral containing many useful components and is also known as olivine. However, olivine is mainly used as an architectural aggregate, and its use as a raw material of soluble phosphorus fertilizer has been extremely limited in crop cultivation.

[0006] Conventionally, as a research using olivine, an invention relating to a soil activator using serpentine is described in Japanese Patent Laid-Open No. 55-137186. The method is to use mycelium culture mixed with limestone, perlite, vermiculite and olivine powder to improve the physical and chemical properties of soil.

Up until now, no soil improver for promoting growth of sugar beet crops containing olivine in sugar beet crops has been disclosed, and a method of treating olivine for growing sugar beet crops under optimum conditions has been reported. There is no.

[0008]

DISCLOSURE OF THE INVENTION An object of the present invention is to provide a soil improving agent for promoting the growth of sugar beet crops.

[0009]

Means for Solving the Problems As a result of intensive studies to achieve the above-mentioned object, the present inventor found that olivine particles were granulated and mixed with the soil of a sugar beet crop, and the olivine had a growth promoting effect on the sugar beet crop. It was found that they had, and that the optimum mixing ratio could be determined. Furthermore, the present inventor sown seeds of sugar beet crops in the olivine dip, and by spreading the olivine-containing composition containing olivine as an active ingredient directly on the standard soil, olivine promotes growth of sugar beet crops. The present invention has been completed with the knowledge that it has an effect.

That is, the present invention has a particle size of 0.01-5.
A soil conditioner for promoting the growth of sugar beet crops, which comprises 0 mm of olivine as an active ingredient. Here, examples of the vegetable crop include daikon radish (young radish), turnip (turnip), chisha (garden), Chinese cabbage (white cabbage), green onion (daikon onion), and perilla (red sesame).

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described in detail below.

The soil improving agent for promoting the growth of sugar beet crops according to the present invention (hereinafter referred to as "the present soil improving agent") has a particle size of 0.01.
The present invention is based on the finding that olivine has a growth promoting effect and a germination promoting effect on sugar beet crops.

This soil conditioner has a particle size of 0.01 to 5.0 m.
It is not particularly limited as long as it contains m olivine, and for example, it is provided as a composition containing a mixture of sand and peat moss to which olivine is added, an olivine immersion liquid, and olivine as an active ingredient. For example, this soil conditioner
Finely powder-processed olivine can be made into a composition which is uniformly mixed with other components. Examples of other components include calcium oxide and zinc oxide.

The olivine contained in this soil conditioner has a particle size of 0.01 to 5.0 mm, preferably 0.15 to 2.0 mm, and a particle size of 90%. Is.

The soil improver is applied to the soil in which the vegetable crop is grown, the vegetable crop itself, and the like. For example, seeds of sugar beet crops are sowed in a mixture of sand and peat moss to which olivine is added; seeds of sugar beet crops are sowed in an olivine powder soaking solution; a composition containing olivine as an active ingredient is spread on standard soil. The present soil improver can be applied by sowing seeds of a vegetable crop in the soil.

The application amount of the present soil improver can be determined by confirming the germination and growth of the vegetable crop after the application of the present soil improver. For example, the present inventor confirmed in the following examples that a mixture of sand and peat moss added with olivine has the maximum effect when the ratio to sand is 10%.

In the present invention, the vegetable crop is not particularly limited as long as it is a herb (vegetable) cultivated for food, and examples thereof include Japanese radish, turnip, chisha, Chinese cabbage, green onion and perilla. Can be mentioned.

This soil improver is very useful for agriculture because it has excellent germination and growth promoting effects on various vegetable crops, and also has an acidity correcting effect in addition to the conventional simple soil improver function.

[0019]

EXAMPLES The present invention will be described in more detail below with reference to examples. However, the technical scope of the present invention is not limited to the following examples.

[0020] In the following examples, Japanese radish (Han River radish, Xing farming seedling product), turnip (Sodamu turnip, Agricultural friend bio product), Chisha (Blue hakama, Daiso seedling product), Chinese cabbage (Large agricultural exchange) Cultivated Chinese cabbage, large agricultural seeds), onion (Gumzanwe green onion, seed friend bio), and perilla (leaf sesame seeds, Dongyuan agricultural seeds) were used.

In the pot experiment, after sowing 50 seeds, the germination state and the degree of stem development from the above-ground part were measured every day from the 2nd day, and the root length was also investigated by selecting at random.

As the test soil, the soil of a greenhouse for cultivation within two years after the installation was used, which is a standard soil and is judged to have a relatively low salt accumulation in the suburbs of Gunpo City, Gyeonggi Province.

[Example 1] Growth promoting effect of sugar beet plants depending on the range of use of olivine A mixture of sand and peat moss at a ratio of 8: 2 (w / w) was used as an untreated control soil. Also, instead of sand, olivine (particle size 5 mm or less) is used in an amount of 5%, 10%, 2
Soil mixed at a ratio of 0% and 30% (v / v) was used. For each of these soils, Japanese radish, turnip,
The seeds of six sugar beet crops such as chisha, Chinese cabbage, onion and perilla were sown.

As in a general pot experiment, a diameter of 10c
The germination and growth conditions are as follows.
The growth chamber is supplied with a luminous intensity of about 10,000 lux for 18 hours a day, and the humidity is 75% or more and the temperature is 2
Maintained at 7 ± 1 ° C. 10 to 20 seeds were sown for each treatment group to supply sufficient water. Along with the initial germination rate,
Five stem lengths of the crops grown from the seeds after 6 days were randomly measured and calculated as an average value.

The results are shown in Table 1 below. In Table 1, 6
All the vegetable crops of the seeds showed the strongest growth at 10% of olivine. It can be seen that olivine has a remarkable effect on the early growth of Japanese radish, turnip, chisha, Chinese cabbage, onion and perilla. Therefore, it can be said that olivine exhibits the function as a soil conditioner and a plant growth promoter.

[Table 1]

[Example 2] Effect of olivine on seed germination and growth promotion of sugar beet crop (pot experiment) A mixture of sand and peat moss at a ratio of 8: 2 (w / w) was used as an untreated control soil. Also, instead of sand, olivine (particle size 5 mm or less) is used in an amount of 5%, 10%, 2
Soil mixed at a ratio of 0% and 30% (v / v) was used. Each of these soils was sown with Japanese radish seeds.

As in a general pot experiment, a diameter of 10c
The germination and growth conditions are as follows.
A luminosity of about 6,000 to 7,000 lux was supplied to the growth chamber for 18 hours a day, and the humidity was kept at 75% or more and the temperature was 27 ± 1 ° C. 10 to 20 seeds were sown for each treatment group to supply sufficient water. Along with the initial germination rate, the stem lengths of the crops growing from the seeds after 5 days were randomly measured and calculated as an average value.

As a result of the experiment as described above, it was found that the germination rate of Osana radish seeds was higher in the olivine-treated group than in the untreated group, and promotion of initial growth was promoted in the olivine-treated group than in the untreated group. Regarding the developmental condition of Japanese radish, it is 2.2 cm when olivine is not treated, and 4.2 cm and 10% when the olivine concentration is 5% (v / v).
7.1 cm for, 20% for 6.2 cm, 30
In the case of%, it was observed to be 5.0 cm. From this result, it was found that the growth state of the Japanese radish was the best when the olivine concentration was 10%.

From the results of this experiment, the low light intensity (6,000
It was confirmed that the initial growth of chisha in the olivine-treated area was significantly higher than that in the untreated area even after the olivine processing at ~ 7,000 lux). Therefore, it was found that olivine has a growth promoting effect on sugar beet crops even at low light intensity.

[Example 3] Oat growth effect of olivine and other soil improving agents A mixture of sand and peat moss at a ratio of 8: 2 (w / w) was used as an untreated control soil. Further, instead of sand, olivine, germanium, or barley stone (particle size: 5 mm or less) was mixed with the soil at a ratio of 10% (v / v) of the amount of sand. Seeds of Japanese radish, turnip and chisha were sown on each of these soils.

As in a general pot experiment, a diameter of 10c
The germination and growth conditions are as follows.
A luminosity of about 6,000 to 7,000 lux was supplied to the growth chamber for 18 hours a day, and the humidity was kept at 75% or more and the temperature was 27 ± 1 ° C. 10 to 20 seeds were sown for each treatment group to supply sufficient water. Along with the initial germination rate, the stem length of the crops growing from the seeds after 4 days was randomly measured and calculated as an average value of 5 stems.

The results are shown in Table 2. From these results, it can be seen that olivine is superior to the other existing soil improvers, bakuhanishi and germanium, in the growth promoting effect of sugar beet crops.

Also, a mixture of sand and peat moss in a ratio of 8: 2 was used as a non-treated control, and 10% (v / v) of the sand dose was mixed with olivine, germanium and barley stone instead of sand. . Seeds of Japanese red radish, turnip and chisha were sown in these soils respectively, and their growth and development levels were comparatively measured to compare their effects with existing soil conditioners. As a result, it was found that germanium and barley stone also have a growth promoting effect on sugar beet crops, but olivine is the best.
