Description

Manufacturing method of soil restoration agent with complex function for solving the problem of salt accumulation in soil}

The present invention relates to a method for manufacturing a soil restoration agent having multiple functions for solving the problem of salt accumulation in soil, and more specifically, as a result of long-term supply of fertilizer components to soil, the soil surface layer is hardened by salt accumulation. It is an invention in the technical field to solve the problem that nutrients and moisture of crops cannot permeate into the soil and are lost to the outside, preventing normal growth and fruition of crops.

The causes of high concentration of salt in agricultural facilities can be factors such as cultivation of tabi, blocking of rainfall, and special environment.

In the case of fertility cultivation, since the facility is intensively cultivated, fertilization tends to occur. If fertilizer is applied excessively, salts such as calcium nitrate, calcium chloride, magnesium sulfate, and ammonia sulfate derived from fertilizer accumulate in the soil.

As a result of measuring the electrical conductivity (EC) of soils in agricultural facilities, it can be seen that it significantly increases during crop cultivation and decreases during non-cultivation period. Depending on the type of soil, high electrical conductivity in volcanic ash soil In addition, even in facility soil, it depends on the number of years of cultivation of crops, and as the number of years of cultivation increases, the electrical conductivity greatly increases.

In the case of rain interception, in general, a large part of the fertilizer applied to cultivated land is washed away with rainwater from the surface or leached underground by rainfall, but salts are not washed away because the facility soil is blocked from natural rain as a basic cover material. As the cultivation continues, salts accumulate more and more, increasing the salt concentration and blocking natural rainfall, so they almost depend on artificial irrigation. Even salts move to the topsoil and accumulate together with the upwardly moving water by capillary action. In this way, a lot of fertilizer is applied to the facility soil, and the applied fertilizer is not removed by rainwater, but rather moves close to the topsoil and accumulates, so the salt concentration continues. result in an increase.

In the case of a special environment, as described above, the environment such as temperature, light, moisture, and air is worse than that of the open field, and the growth of crops slows down and becomes weak in poor environments such as low temperature, weak light, and lack of carbon dioxide gas. The salt absorption rate in the ramen soil is low, the temperature higher than that of the open field promotes evapotranspiration, and the amount of irrigation is insufficient in the dry soil.

In this way, salt accumulation is described as a phenomenon in which salt accumulation in the surface layer occurs in dry or semi-arid regions where rainfall is low and evaporation is high. Such excessive salinization reduces the vitality of crops, inhibits the absorption of nutrients and water by salt osmosis, and causes urea deficiency in crops due to excessive and insufficient nutrients in the soil. This causes poor growth of crops, reduced productivity, lowered quality, and lowered awareness.

In a normally balanced soil, water and nutrients permeate into the soil and are well delivered to the roots, resulting in high yields of high-quality crops. In order to improve the productivity of farmhouses and grow high-quality crops in large quantities, due to the occurrence of problems that crops wither due to lack of moisture and are not supplied with nutrients, they cannot grow normally and produce high-quality fruits. A technical solution to solve the problem of salt accumulation is absolutely necessary.

So far, as a means to solve the problem of salt accumulation in the facility cultivation area, it has been implemented using methods such as reasonable fertilization method, strengthening of the holding capacity (retention capacity) of fertilizer components by soil improver, washing method of salt with water, culvert drainage facility method, etc. However, as the decontamination effect is not very high and a large amount of manpower and equipment are required, it has many limitations in order to solve the problem of salt accumulation in the soil at the economic level of the farmhouse.

Samples prepared in Comparative Examples 1 to 6 and Examples 1 to 6 were supplied during each crop cultivation process, and the yield of crops per unit area and the growth status of crops during the cultivation process and nutrients of crops including water permeated into the soil Penetration and electrical conductivity of the soil were confirmed. The evaluation of the crop yield, growth status, and penetration of water into the soil was evaluated by farmers who had been cultivating fruits and vegetables in greenhouses for 16 years. was measured, and the results are shown in Table 1.

As shown in Table 1, the average daily yield per 200 pyeong when the surfactant that can lower the surface tension of Comparatives 1 to 6 is not included in water and when the fertilizer component is included is 87 kg and 98 kg for strawberries, respectively. kg, and in the case of cucumbers, 154 kg and 188 kg, and in the case of red peppers, 15 kg and 27 kg, while the only surfactant for lowering the surface tension in the water of Examples 1 to 6 was used alone. The daily average yields per 200 pyeong when the water was included or when surfactants and fertilizers were included in water were 126 kg and 154 kg for strawberries, 196 kg and 264 kg for cucumbers, and 24 kg for peppers. and 36 kg. In this way, when crops are cultivated continuously for a long period of time in the facility cultivation area, the soil of the crop plantation area is firmly hardened due to salt accumulation, and the water or nutrients necessary for the growth process of the crop cannot permeate into the soil and are lost to other places, causing damage to repeated cropping. However, it was confirmed that when a surfactant capable of minimizing surface tension is supplied to the soil, nutrients from water and fertilizer easily penetrate into the soil and can be easily absorbed as nutrients by the roots of crops. In addition, the visual situation of the crop growth process, the crop yield of water supplied to the situation or ridge during the crop growth process, and the value of the soil conductivity showed a similar trend to the cause of soil salinization related to the increase or decrease in the daily average yield of the crop. indicates

Therefore, the present application can not only restore hardened soil due to salt accumulation during the process of continuous cropping of vegetables or fruits in facility cultivation for a long time, but also in the case of hardened soil by improving the permeability by minimizing the surface tension of water or fertilizer containing water. It is expected to greatly contribute to the normal growth of crops and high-quality, high-yield fruits while reducing damage to repeated cropping by providing water and fertilizer components to permeate well to the roots.
