Description

Method of Adapting Non-Halophytes to Halophytes using Soil Amelioration Composition}

The present invention relates to a method for improving non-saline plants into saline plants.

In Korea, three sides are surrounded by the sea, and most of them are composed of coasts, and there are many salt spots. The salt salts are mainly distributed on the southwest coast, and some areas have been used as salt fields since the 1900s. As a result of the development, many tidal flats were created by reclaiming tidal flats.

However, with the recent increase in environmental awareness, they have been showing interest in environmental restoration projects for salt farms. As salt concentration increases due to salt invasion or evaporation of soil water, it is a land where plants are obstructed by growth, and most of them are coastal sand dunes, sandy areas, and reclaimed land where seawater has been invaded. In particular, reclaimed land has a very large area, many of which have been matured to increase the yield of rice, but relatively new land where reclamation projects have been completed recently, and responsiveness is difficult when irrigation water is insufficient. It is often damaged.

Some coastal and tidal flat areas have recently been widely used as ecological experience sites and educational sites. Especially, the beach area is important as a resting place or a habitat for native beach plants, and the dyed plants forming beautiful colonies are unique to the beach. It becomes the important scenery element constituting the scenery of the city. However, beach plants are gradually disappearing due to the development of coastal areas.

As such, the necessity for the development of the seashore area and salt field can preserve the native salt plants and at the same time form the landscape of the seashore area, and provide the user with a resting place and a place for education, and at the same time give the conservation of the ecosystem.

Salinity refers to the number of grams of total solids contained in 1 kg of seawater. The unit is expressed as ‰ and is also referred to as salinity and salinity. The salinity of the world's oceans averages 35 ‰, and the salt concentrations vary slightly from region to region.

About 96.5% of seawater is pure water, and about 3.5% is salts. In addition, it contains almost all elements of the earth, such as dissolved gas and insoluble mixture particles. Among these, inorganic salts are the most important component of seawater, and are distributed in seawater while interacting closely with land and the atmosphere. Inorganic salts are mostly dissolved in seawater in ionic state, mainly chlorine and sodium ions accounting for 85%, and sulfate ions, magnesium ions, calcium ions and potassium ions account for most of the rest.

Plants are hampered by growth of salts due to salt invasion or evaporation of soil water. Plants are hampered by salt growth at salt salt grounds. Secondly, the soil's physicochemical properties are poor. 3) Neutral or weakly alkaline soils are suitable for plant growth, but salty soils are strongly alkaline, and 4) plants other than salt plants This is because an obstacle occurs.

The first plants to grow in salt fields are "trees," which are directly affected by salty sea breezes on the coast and that can reliably grow in areas with very low salt levels. These trees have a lustrous, rust-resistant form with the development of cuticles on the leaves, and the stems or branches are bent inland by the action of excellent sea breezes, and the leaves or branches above are artificially cut. It is as flat as it is.

In the warm coastal areas of southern Korea, evergreen broad-leaved trees such as Gomsol, Camellia, Sasslepi, Ileum, Cypress, Thick, Oyster, Prunus, Hex, Prunus, Sendal and True Trees are distributed. Jindo iris trees, Geoje island palm trees, and Mt.

The second is a 'herb' plant that grows in salty land. On the beach and inland there are salt lakes and salt plants growing in salt rock. Salt plants are often fleshy stems and leaves and classified into dry salt plants and wet salt plants, depending on the moisture content of the growing area, but both salts are contained in the cells, resulting in high osmotic pressure. Because of this, the soil can absorb water even when the infiltration rate is high. Most of the salt plants in Korea are distributed along the coast, and most of them are planted with over 40% of the salt plants of rice and chrysanthemums, and most of them grow and form colonies. Reed, mud grass, pug grass, buckwheat, squirrel, turkey herb, namunjae, seaweed greens, rosemary, cedar mugwort, disappointed herb, large twig dung, bark, sanjo grass, moss moon, clam barley, mezagi, zombie sedge, It is a natural plant that grows wild dogs, mussels, clans, horseradish, panaxanthus, bergamot, goblin needles, and persimmon bark. This grows. In addition, due to the strong propagation power of naturalized plants, habitats are spreading around areas where mound construction and artificial interference occur.

In recent years, the vast west coast tidal flat has been made into reclaimed land and turned into agricultural land, and the vast salt marsh vegetation is gradually disappearing due to reclamation for the construction of new cities, new airports and new ports. The salt marshes are also rapidly being destroyed, so it will be difficult to preserve the salt vegetation communities without protecting the vegetation of salt flats such as tidal flats, salt marshes and coastal sand dunes.

In addition, harvesting salt plants from the salt plant community of salt farms is not possible in terms of environmental protection. Therefore, non-salt plants have to be planted directly in salt farms, but most of them die due to high salt concentration. . Thus, in order to increase the population of salt plants currently distributed in salt ponds, it is necessary to breed the salt plants by breeding non-salt plants so that they can be grown at high salt concentrations. However, to date, there are no examples of brine plants by breeding non-salt plants.

Accordingly, the present inventors have conducted research to improve non-saline plants to grow at high salt concentrations, such as saline plants currently growing in salt sea salt, for the purpose of preserving the salt seaweed colony of salt sea salt. The soil improver developed by the inventors is mixed with the soil of salted salt to grow non-salted plants to improve varieties of non-salted plants. The present invention was completed by confirming that it was possible to form a colony.

Accordingly, it is an object of the present invention to provide a method for improving non-saline plants into saline plants using soil improving agents.

In addition, another object of the present invention to provide a soil improving agent for the production of salt plants.

Other objects and advantages of the present invention will become apparent from the following detailed description and claims.

According to one aspect of the invention, the present invention comprises the steps of (a) pre-treatment of non-saline plants in a charcoal and zeolite mixture for 20 to 30 hours;

(b) pre-cultivating non-saline plants on a vegetation-based vegetation-based mat containing 5 to 40% of a soil modifier in a sandy soil having a salt concentration of 10 to 35 ‰. It provides a method to improve the salt to plant.

In addition, according to another aspect of the present invention, there is provided a soil improver for use in improving non-saline plants to saline plants.

As used herein, the term 'salt plant' refers to a land containing salt, that is, a plant that can grow in salt fields. Salt damage has the effects of high osmotic pressure of the surrounding soil containing salts and physiological adverse effects of high concentrations of salts in the plant body. However, salt plants are resistant to salts, that is, they are resistant to high concentrations of salts and are therefore capable of growing in salt ponds.

On the other hand, as used herein, the term “non-saline plants” refers to plants that are difficult to grow in salt fields, unlike salt plants, which are slow to grow and difficult to grow on land containing salts.

The reason why the non-chlorinated plants are used in the method of the present invention is to prohibit the use of the salt plants that inhabit salt spots in order to protect the environment. In other words, the context of the present application is to adapt non-saline plants to high concentrations of salts, and to select salt-tolerant plants with saline toleration and plant them in salted sea salts, whereby they can grow and form colonies in salted sea water. .

Non-chlorinated plants usable in the improved method of the present invention are seeds and seedlings of non-chlorinated plants.

As a non-inflammatory plant, various plants of the family Asteraceae, Asteraceae, Burdock, Asteraceae, Magnolia, Forageaceae, Cruciferaceae, Legumes, Needle flower, Buddha, and Sukki, may be used. Species of plants are available.

(xi) buddha family: Lythrum salicaria ; And

(xii) Caryophyllaceae: Silene armeria and Dianthus chinensis .

In the method for improving the non-chlorinated plants of the present invention to salt plants, it is preferable to perform a pretreatment step before germinating seeds of the non-chlorinated plants to increase the germination rate. The pretreatment step is a step in which seeds are buried in 1-2 mm granular charcoal and zeolite mixture for 20 to 30 hours, and the pretreatment step is preferably treated for 24 hours. Seeds pretreated in charcoal and zeolite mixtures have a uniform germination, improved germination rate, and good lubrication compared to seeds not subjected to this pretreatment step. Charcoal or zeolites have high ion exchange capacity and can detoxify toxic substances by attracting these ions of toxic substances with hydrogen or other cationic functional groups to make them electrically mainstream. In addition, char or zeolite can significantly inhibit the activity of anaerobic bacteria by supplying oxygen having strong oxidizing power in exchange with water in water.

Soil modifiers used to improve non-chlorinated plants in the improved method of the present invention and soil modifiers for improving non-chlorinated plants to salt plants are 25-35% organic matter, 1-2% nitrogen, 0.1-0.5% kali, 0.1 phosphoric acid It is preferred to comprise 30-80% by weight of organic fertilizer containing -1.0% and 2.5% of calcium and 0.001-10.0% by weight of zeolite.

In the improved method of the present invention, the non-salting plant can be adapted to the salt by using a culture soil containing 5 to 40% of the soil improving agent in the sandy soil having a salt concentration of 10 to 35 ‰. It is preferably blended at 30%, most preferably at 30%.

(1) organic fertilizer

As an organic fertilizer, it is preferable to use fecal soil which is an organic substance which an earthworm fermented the phosphorus excreted by man. Fecal soil contains 25 kinds of antagonistic microorganisms discharged from the earthworm body, organic persistent enzyme and inorganic components. The fecal soil is free of gas and stable, and its physical and chemical properties are similar to ripening compost as it passes through the earthworm body, and does not cause any damage to the plant even if it is directly in contact with the root of the plant or excessively used. In addition, the inside of the fecal soil has a lot of pores and the specific surface is very large, it is excellent in the cation substitution capacity (EC) and the binding force, and reduces the salt disturbance of the soil.

<Components and Chemical Properties in Fecal Soil>

ingredient Organic matter 30% nitrogen 1.4% Carly 0.3% Phosphoric Acid 0.7% calcium 3.5% Chemical properties C / N 21% EC 0.9% pH 7.3

Fecal soil having the ingredients and chemical properties as shown in the table ① ① improve the water retention, absorbency and breathability is excellent root promoting effect, ② contains the active substances, antibiotics of plants to promote growth, ③ prevent soil acidification ④ As a mature yeast improver in the yeast state, oxygen deficiency and heat are not generated at all due to the ammonia nitrogen, which is common in the process of maturation. ⑥ It is easy to use as granule-shaped particles ⑥.

(2) zeolite

Zeolite is a part of green tuff that has been changed deeply under high pressure and temperature in the deep underground, and has been transformed into a completely new mineral. It is used as a fertilizer additive and pesticide extender in addition to the soil improver in agricultural and landscape materials.

The biggest characteristic of zeolite as soil improving agent is cation substitution capacity (capacity to adsorb and store cations), so-called CEC is very large, and is excellent in adsorbing and storing cations. Although the CEC of Korean soil is about 20 meq / 100g, the CEC in sandy lands such as coastal sand dunes is very low, less than 5 meq / 100g. However, zeolite's CEC is 150-200 meq / 100g, about twice the size of montmorillonite-based bentite 80-100 meq / 100g.

<Components and Properties of Zeolites>

division Zeolite Bentnight ingredient Silicate (Si ₂ O ₂ ) 66.2% 69.5% Alumina (Al ₂ O ₃ ) 11.5% 15.4% Iron (Fe ₂ O ₃ ) 1.67% 1.87% Magnesium (MgO) 0.66% 3.75% Calcium (CaO) 2.10% 1.87% Potassium (K ₂ O) 4.30% 0.18% Sodium (Na ₂ O) 1.04% 0.40%    CEC (meq / 100g) 155 81    Major mineral Clinoptilolite Montmorillonite

In addition, as shown in the following table, the zeolite is not merely a large CEC, but because the effect is continuous, the soil improvement effect is better.

division CEC according to ripening period 0 days 1 week 1 month Zeolite 68.3 (100) 69.7 (102) 69.3 (101) Bentnight 56.3 (100) 48.2 (86) 47.0 (84)

The numerical value in the parenthesis of the said table | surface is the index (meq / 100g) which made 0 the day 100.

In addition, the zeolite selectively adsorbs ammonium and potassium, and does not adsorb phosphoric acid, thereby suppressing the loss of ammonium ions and replaceable bases, promoting inefficiency of nitrogen, phosphoric acid and kali, and suppressing volatilization of ammonia gas, Like fertilizer, it is not directly absorbed and used for the growth of crops, but it is a soil improver that indirectly increases or improves the quality of the crops by improving the soil properties.

The improved method of the present invention is implemented through the following steps:

(a) preparing a cultured soil by mixing 10-40% of the soil improving agent of the present invention to the salt of the salted salt or the soil having a salt concentration of 10-35 ‰ equal to the salted salt; And

(b) seeding or growing seedlings or seedlings of the non-inflammatory plants of the present invention on the flat vegetation-based mat of Figure 1 or the uneven vegetation-based mat of Figure 2 containing the culture soil prepared in step (a) step.

In the improved method of the present invention, the culture soil of step (a) preferably contains 10 to 40%, more preferably 10 to 30% of the soil improving agent of the present invention. According to a preferred embodiment of the present invention, the growth degree when the non-saline plants are grown in the culture soil containing 30% of the soil improving agent of the present invention is the best.

In the step (b), the growth of the non-saline plant is possible through any method of culturing using a pot or a vegetation-based mat (Korean Patent Application No. 2004-108935) designed by the present inventors. In the case of pot culture, it can be carried out using a conventional pot culture method known in the art.

The vegetation-based mat of FIG. 1 may be used for germination of seeds and growth of germinated seedlings as flat plates. The vegetation-based mat of FIG. 2 may be used for germination of seeds and growth of germinated seedlings as irregularities.

In the flat vegetation-based mat 10 of FIG. 1, the mesh members 11 and 12 are stacked up and down, and the insertion portions 20 are formed between the mesh members by sewing at regular intervals. The mesh members 11 and 12 are sewn in the width direction (y) rather than the length (x) direction, for example, the (x) direction is 1,000 cm and the (y) direction is 100 cm. Here, the mesh members 11 and 12 have the same width so that both sides 13 and 14 are formed flat after sewing. Here, the sewing interval is suitably about 6.0cm to 8.0cm, the lamination thickness of the mesh members (11, 12) is suitable for 1.5cm to about 2.0cm. Meanwhile, the mesh members 11 and 12 are woven with any one of coconut fiber, jute and rice straw. Among these, the mesh members 11 and 12 are most preferably woven from coconut fiber, which is relatively high in tensile strength, inexpensive, and readily available. For example, the weaving spacing is suitable for about 0.1cm to 1.0cm.

In the present invention, since the mesh members 11 and 12 are made of natural organic material yarns such as coconut fiber, jute yarn, and rice straw, there is no environmental pollution even after construction, and it is excellent in breathability, water holding capacity, and bobbin power to improve plant growth. . On the other hand, the mesh member (11, 12) is sewn to the edge so that the opening is formed on one side or both sides of the insertion portion (20). By sewing the edge of the mesh member, while using the vegetation-based mat 10 there is an advantage that the vegetation primitives 60 inserted into the inserting portion 20 does not spill or flow to the outside.

The flat vegetation-based mat of Figure 1 can be carried out by simultaneously inserting the seed directly into the insert portion to germinate and grow, and improved by installing a flat vegetation-based mat including the grown plants in salted ground This makes it easy to adapt the salt plant to salt salt.

The uneven vegetation-based mat 10 'of FIG. 2 has a larger width of any one of the mesh members 11' and 12 ', so that one surface 13' has a bone 15 shape after sewing. ') Is formed flat. In particular, the ratio of the large mesh member 11 'and the small mesh member 12' is about 1.3: 1, and the sewing interval is about 9.0cm to about 10.0cm, and the mesh members 11 'and 12 are suitable. The lamination thickness of ') is suitable for 4.0cm to 5.0cm.

The uneven vegetation-based mat of FIG. 2 has an uneven shape, and allows seed to be grown by directly planting seeds in the insertion part and then grown or germinated seed.

In the growth stage of the non-saline plant of the present invention, it is preferable to include 7-8% of ammonium phosphate (NH ₄ ) H ₂ PO ₄ in the culture solution, preferably water, during the growth, and add the same to the plant. Phosphate ammonium (NH ₄₎ H ₂ PO ₄ is a compound exhibiting an acid, including 12% of nitrogen and phosphoric acid _{P 2 O 5 61%, NH} 4 + ions OH ^- and neutralize the soil in combination with the ionic phosphate P ₂ Increases the O ₅ content to play an effective role in vegetation. That is, by adding ammonium phosphate to neutralize the acidity of the soil, the remaining phosphoric acid plays an effective role.

Through the improved method of the present invention, non-saline plants become resistant to salts, and growth is possible without high death even at high salt concentrations such as salt salts (see FIG. 3). That is, through the improved method of the present invention, the non-saline plants are improved to the saline plants having salt resistance. According to a preferred embodiment of the present invention, by adapting the soil improving agent to the salt of the salted salt to adapt the non-salt plants to be resistant to salt and then planting it directly in the salted salt, Compared to the plants grown in the soil, the growth rate and growth rate are excellent, as well as the formation of colonies.

Hereinafter, the present invention will be described in more detail with reference to Examples. These examples are only for illustrating the present invention in more detail, it will be apparent to those skilled in the art that the scope of the present invention is not limited by these examples in accordance with the gist of the present invention. .

Example 1: germination experiment of seeds according to salt concentration

For the seed germination experiment according to the salinity concentration, four kinds of wild seed of five kinds of introduced wild flowers and the seeds of dianthus, bee stinger, cucurbita and bee yellow Used.

The nine kinds of seeds were placed in a chalet, and the salinity of the cultured soil was varied from 2 to 12 ‰, and germinated at an average temperature of 80 to 85% and a humidity of 25 to 30 ° C. The germination rate according to the salinity concentration is shown in Table 1.

division River water Salinity Concentration Salinity Concentration Salinity Concentration Introduced species Gold cock 73% 70% 46% 31% Ludvecchia 74% 71% 51% 34% Shasta Daisy 66% 61% 40% 28% Sticky Sprouts 78% 73% 56% 42% Local species Dianthus 72% 42% 31% 22% Hummingbird 75% 36% 28% 18% A worm 55% 33% 27% 15% Yellow 71% 58% 34% 21%

The germinated seeds were grown in an incubator for 15 days under the same conditions as the germination conditions, and then the degree of growth of the plants was observed and the results are shown in Table 2 below.

division Wild Flower Growth Rate Native Wildflower Growth Rate River water Relatively early growth Relatively early growth Salinity 2-3 ‰ Early growth is good, but growth is slow Early growth is good but slow growth Salinity Concentration 4-6 ‰ About 10% of deaths due to salt disorder About 30% of deaths due to disorders related to salt Salinity Concentration 8-12 ‰ Difficulty in growing more than 30% Difficulties in growing more than 50%

As shown in Table 1, the germination of the seeds appeared to be relatively stronger to salt than the introduced species wildflowers, and among the native species, dianthus and bee-yellow was relatively resistant to salt. In addition, as shown in Table 2, the growth of the germinated plants also showed that the introduced species wildflowers are relatively resistant to salt rather than native species.

Example 2: growth test of seedling according to salinity concentration

As a coastal sand column with high salt concentration and wetland, sand was collected from the coastal sand column of Taean Legality, Chungnam, and experimented in a plastic house. Experimental varieties were used five introduced species wildflowers and native species wildflowers used in Example 1. The seedlings of the nine varieties were planted in pots and grown as 10 pots for each plant. Seedling growth conditions are as follows.

(a) experimental soil

In the comparison group, the experiment was conducted using only the coastal sand, and the experimental group was mixed with 10-30% of the soil improver in the coastal sand. Soil modifier was a mixture of 50% fermented organic fertilizer and 2% zeolite.

(b) experimental conditions

After removing the soil soil of each pot in each pot, the roots were planted in a good state. After planting, the plants were grown for 20 days with a humidity of 80-85% at a temperature of 25-30 ° C.

Growth status of seedlings is shown in Table 3-5.

Growth day Growth Soil improver 5-10% + Coastal sand sand Coastal sand sandy soil with salinity of 20-23 ‰ 10 days Excellent early growth Initial 20% death (injury to salt) 20 days Slow growth due to salt Slow growth or about 55% mortality

Growth day Growth 10-15% Soil Improving Sand Sand Coastal sand sandy soil with salinity of 20-23 ‰ 10 days Excellent early growth Initial 10% death (disruption of salt) 20 days Low growth disorders for salt Slow growth or dead about 30%

Growth day Growth 30% Soil Improving Agent + Coastal Sand Sand Coastal sand sandy soil with salinity of 20-23 ‰ 10 days There is no problem in early growth Rooting is good and symptoms of salt appear 20 days There is no obstacle to growth like early growth Slow growth or hinder growth

As shown in Table 3-5, when the seedlings are directly planted in the sandy soil of salted salt, relatively early growth is possible, but it can be seen that over time the disorder for salt appears. However, when the seedlings were planted by mixing the soil modifier with the proper amount in the sandy soil of salted salt, it was shown that there are less obstacles to salt than those planted in the sand of coastal sand.

Therefore, it can be seen that the growth state is much better than the case of planting the plants directly in the salted salt when the plants are grown in the salted salt after cultivating the plants by properly mixing the soil improving agent in the salted sand.

Example 3: Salt Hedge Plant Experiment of Plants Adapted to Salts

Planting experiments of salt-adapted plants at the salt beach were carried out on the coastal line of Taean Legality, Chungnam. In the same manner as in the experimental method of Example 2, in the culture soil containing 10-15% and 30% of soil modifiers in the sandy soil of coastal sand, the reeds, strings, and parts were grown to adapt to salt, and then planted in the salted ground. The experiment was performed.

First, the residual salinity concentration within 30cm of the topsoil of the test subject area was measured, and the plants identified as having salt tolerance in the measured salinity concentration range of ± 5 ‰ were used as the experimental group. Reeds, buds, and strings were used to grow and mix. Reed species, reeds, and strings were used only for salted sand soil.

The salt concentration of the coastal keys of Taean Legal District, Chungnam, was 20-23 ‰. Each seedling (4 pots) is a salt growing adaptation experiment group 30 weeks, the growth of the mouth more than 30cm in the root stem and salt-tolerant, and the growth of the root stem is a vigorous state without any loss of soil when the pot is removed Was used.

Salted vegetation results of plants grown to have salt resistance in coastal sand dunes mixed with 10-15% soil improver are shown in Tables 6 and 7 below, and salt tolerant in coastal dune sand mixed with 30% soil modifier. The salt vegetation results of the plants grown to stand are shown in Tables 8 and 9 below.

Adaptation to salt was achieved and growth was excellent.

division Growth Status of Plants Grown in Coastal Sands  Growth status of plants grown in sandy soil with 10-15% soil improver Growth  Adaptation to salt was excellent, but root stem development and mouth growth grew slowly at first.  The growth rate was similar or slightly better than that of plants grown in planting soils, but the growth rate of plants was about 10% higher.

Taken together, if the plants grown in coastal sands were planted in coastal sands, 10-15% and 30% of soil modifiers were grown in coastal sands. The degree of growth, growth rate and growth were excellent. In other words, when seedlings were planted in the salt ponds, relatively early growth was possible, but it was judged that the disturbance of salts appeared over time.

As described in detail above, the present invention provides a method for improving a non-chlorinated plant to a salt plant and a soil improving agent for use in the method. Plant improvement method of the present invention by mixing the soil improving agent of the present invention in the salted soil to grow non-salt plants can be improved to grow at high salt concentration, so the improved plants are grown in salt fields like salt plants It can be usefully used to preserve the environment of salt ponds.

Having described the specific part of the present invention in detail, it is apparent to those skilled in the art that the specific technology is merely a preferred embodiment, and the scope of the present invention is not limited thereto. Thus, the substantial scope of the present invention will be defined by the appended claims and equivalents thereof.
