(In Formula 1, n is 3-12.)

The coco peat is an organic fertilizer component such as peat moss, and is an organic material made by grinding and processing the coconut dust portion from which the fiber has been removed from the coconut shell. Coco peat is a pure natural organic material that is environmentally friendly, has excellent drainage and breathability, is resistant to microbial penetration, has stable oxidation conditions, and contains significant organic nutrients and trace elements. Unlike compost, coco peat has the property of not decomposing for a long period of time, so it ensures that nutrients, moisture and oxygen are smoothly supplied to the roots of plants grown in the initial seedling medium. In addition, because coco peat decomposes over a long period of time, it allows the condition of the topsoil to be maintained at a constant level. The water retention capacity of coco peat is extremely high, at 6 to 9 times the weight of the dried material, and the void content is over 90%, preventing the soil from solidifying and maintaining breathability.

Unlike coco peat, the coconut cake refers to the residue (coconut oil cake) left after extracting the oil from the inside of the coconut (white), and contains protein (16%0, fat (8%), fiber (12%), moisture ( 10%), etc., so it is used as pig feed. In the present invention, it is used as a soil conditioner.

When bentonite is immersed in hydrochloric acid and activated with acid, calcium hydroxide is generated as a reaction product. This is a substance that interferes with surface modification, and the calcium hydroxide generated in the previous step can be removed by mixing the calcium oxide with distilled water and stirring it at medium temperature.

The poly(potassium acrylate-acrylamide) copolymer is a functional polymer that combines hydrophilicity and water insolubility. It has a large absorption capacity ranging from hundreds to thousands of times its own weight, and has the characteristic of not releasing water even when external pressure is applied. . And it has numerous hydrophilic groups, so it absorbs ammonia and improves its holding power. Additionally, high-absorbency polymers absorb solvents to form a swollen gel, which improves breathability by widening the pores between soils.

The compound represented by Formula 1 is a silicone-based compound containing an anthraquinone-2-carboxamide functional group at both ends, and contains an anthraquinone derivative structure, which is effective for plant growth and has synergy in soil improvement. Adds effect. In Formula 2, n is more preferably 6-10.

To confirm the effect of the soil conditioner according to the present invention on improving nitrogen fixation, an experiment was conducted using soybean seeds as follows.

First, soybean seeds were treated with 70% ethanol (1 minute) and 2% sodium hypochlorite (NaOCl) (1 minute) to sterilize the surface, then washed with sterilized distilled water and placed in a small plastic pot (36㎠) containing sterilized culture soil. were sown and grown in a greenhouse for 2 weeks.

The soybean seedlings grown in this way were transplanted into pots (15 cm in diameter) containing 500 g of the soil conditioner of Example 1 and Comparative Example 1 and 1 kg of sterilized soil, respectively, mixed well and grown in a plant incubator at 23-28°C. The control group used only 1.5 kg of sterilized soil without using any soil conditioner. Then, after another 2-3 weeks of cultivation, the degree of nodule formation was observed on the soybean roots.

Five experts observed root nodules on soybean roots and scored them from 1 to 5 (1 point: almost no nodules observed, 2 points: very few nodules observed, 3 points: some root nodules observed, 4 points : A large number of root nodules are observed, 5 points: A large number of root nodules are observed, and root nodules of a certain size or larger are observed. The average of the scores evaluated is shown in Table 1.

Example 1 Comparative Example 1 control group Degree of root nodule formation 4.6 3.9 1.1

As shown in Table 1 above, the effect of the soil conditioner according to the present invention was confirmed.

<Experimental Example 2> Crop growth analysis

In order to confirm the effect of promoting crop growth according to the soil improvement method according to the present invention, an experiment was conducted using pepper seeds as follows.

Pepper seeds were surface sterilized using 70% ethanol (1 minute) and 1% sodium hypochlorite (NaOCl) (3 minutes) and then washed several times with sterilized distilled water. 500 g of the soil conditioner prepared in Example 1 and Comparative Example 1 was mixed well with 1 kg of sterilized soil, and pots (15 cm in diameter) were prepared and planted with pepper seedlings grown for 2 weeks. The control group used only 1.5 kg of sterilized soil without using any soil conditioner.

In addition, 500 g of the soil conditioner prepared in Example 1 and 500 g of water were mixed well with 1 kg of sterilized soil, then 500 g of the auxiliary conditioner prepared in Example 2 was added, and a pot containing this (15 cm in diameter) was added. was prepared and the pepper seedlings grown for two weeks were planted and cultivated.

Twenty plants were used for each of Example 1, Example 2, Comparative Example 1, and the control group, and harvesting was performed after two weeks of cultivation.

The stem length and root length of each harvested Example, Comparative Example, and Control plant were measured, and the average over 20 weeks was calculated and shown in Table 2.

Example 1 Example 2 Comparative Example 1 control group Stem length (cm) 39.2 41.4 33.7 15.0 Root length (cm) 30.4 32.8 25.0 12.1

As shown in Table 2 above, the effect of the soil improvement method according to the present invention was confirmed.
