Description

Soil cultivation method of ice plant {CULTURING METHOD OF ICE PLANT ON SOIL}

The present invention relates to a soil cultivation method of the ice plant, and more specifically, it is possible to mass-produce eco-friendly through soil cultivation of the ice plant, and to maintain the content of the functional material of the ice plant even under salt concentration control or salt-free. And a method for cultivating a large amount of high value-added ice plants in soil in a way that can be maximized and excellent in terms of palatability.

An ice plant is a salty / succulent plant belonging to the pomegranate family of Sukjukmok, which has a lot of Epidermal Bladder cells in its stem and leaves when stressed by temperature and other environmental factors. Formed, it can store NaCl and various nutrients. However, the ice plant is a plant with a unique physiology that stops growth by causing CAM (Crassulacean Acid Metabolism) when excessive stress is applied.

Iceplants are distributed in Europe and Africa, as well as the southern continent of Australia, to the north of Exmouth and to the west of the Australian coast. Because of its unique physiology and ability to accumulate salt, the plant has been used only to remove salt from salty areas.

In Korea, the seaweed is sold as a plant similar to an ice plant, but these products contain high concentrations of salt and heavy metals, which are harmful to the human body, and are therefore ignored by some consumers. Salty is very dangerous, especially for patients with high blood pressure and diabetes.

The ice plant also has a natural taste of salty, but according to the experiments by the present inventors have a variety of nutritional ingredients, it was confirmed that it is possible to control the salty taste (it can eliminate the low concentration and salty itself) is excellent in terms of palatability In the future, many demands are expected as raw materials for processed foods.

However, there are no techniques for controlling the saltiness at the same time as it is possible to cultivate large quantities without loss of nutrients through the soil cultivation method for the ice plant. New methods of cultivation that can be fused with other industries (cosmetics, diet product groups, etc.) through the extraction and maximization of various functional substances present.

It includes.

Hereinafter, the content of the present invention will be described in more detail step by step.

The soil cultivation method of the ice plant according to the present invention is due to the characteristic of storing all ionic components absorbed into the roots in the epidermal bladder cell (hereinafter abbreviated as EBC) due to the characteristics of the ice plant, preferably harmful to humans such as heavy metals. It is required to prepare soil without urea. Preferably, artificial soil (pit moss, pearlite, vermiculite, etc.) capable of preventing the spread of pathogens may be used together with the treated soil. At this time, the ratio of the artificial soil and the top soil is 1: 5 ~ 5: 1, preferably a ratio of about 4: 4.

(1) Sowing process

In the present invention, two to three seeds of the ice plant is planted in the germination plug and then covered with a thin layer of soil. At this time, preferably about 1 to 2mm in the seed so that the seed is hidden to cover the soil thinly.

Then spray water carefully using sprayer immediately after sowing. Germination takes place about one week after sowing, and in case of two or more germinations, the germination is carried out before planting. The germination temperature is 20 ~ 30 ℃, humidity is 50% or more, preferably 60 ~ 80% is the optimal environment. The light conditions for germination can be both cancer germination and photo germination, but photo germination is more preferable in terms of high germination rate.

(2) seedling transplanting and cultivation / harvesting

After germination, the leaves of the ice plant is 2-5 pieces, preferably 3-4 pieces, and after about 15-20 days after sowing, when the total size becomes about 2cm, the planting is performed at intervals of 50-60cm. At this time, since the root of the ice plant is thin, care should be taken not to cut.

About 5-20 days, preferably 10-15 days after the meal, 0.01-2.0% (w / w), preferably to increase the content of functional substances and other nutrients according to the increase of EBC of the ice plant Make less than 0.5 ~ 2% (w / w) salt water and sprinkle it on the root side. If less than 0.01% (w / w), it is difficult to expect the effect of stress due to salinity, if more than 2% (w / w) CAM will occur, and there is a fear that harvesting will be difficult because flowering begins There is.

In addition, when the salt treatment is too young, the rate of death due to physiological disorders is increased, so it is preferable to do it after about 30 days after germination.

However, when the purpose is to increase the functional material that is not reproductive, it is also possible to perform a higher concentration of salt treatment than in the case of reproductive cultivation. This is due to the salinity stress, an increase in the functional substance in the ice plant at high concentrations of salinity is noticeable. In other words, if CAM progresses, it cannot be used for food, but it can be applied as an application product using the substance by increasing the functional substance. At this time, the treatment method is to treat the salt concentration of the desired target from the beginning, but if the purpose of increasing the yield is preferred to treat the salinity sequentially in a short period of time rather than treating a high concentration of salt at once.

In the case of treatment by dividing the salt concentration by growth, for example, if the treatment is gradually increased to increase the concentration according to the development, it is preferable to reduce the probability of occurrence of physiological disorders due to the resistance to stress. It is also possible to adjust the concentration for salty taste by using this method. Examples of salt concentration control in the present invention are as shown in Table 1 below.

Harvest purpose division Sowing and germination Seedling Formally harvesting Salinity
(weight%) 0 0 to 0.5 0.5-1.5 1.5 ~ 2.0 Processing date About 10 days 10-15 days 50-65 days About 7 days

Purpose of increasing functional substance division Sowing and germination Seedling Formally harvesting Salinity
(weight%) 0 0.5-1.0 1.0-2.0 2.0 ~ Processing date About 10 days 10-15 days 50-65 days About 7 days

In addition, if only for the growth of the ice plant, it is also possible to cultivate by supplying only water to the nutrient compound soil without adding salt water. In this case, it is required to adjust the temperature and humidity, according to the present invention, the temperature is 20 to 28 degrees humidity 50% or more, preferably 50 to 80%. As such, by adjusting the temperature and humidity without adding salt water, there is an advantage of being able to harvest about 10 days ahead of the salt water. However, EBC cells in ice plants are markedly smaller than when stress is generated by brine, and leaf growth is more prominent than stem growth.

When selling ice plants for reproductive purposes, this growth can be a factor in value depreciation. The leaves are small, the stems are thick and long, and many EBCs can be valued as a commodity, so it is more preferable to incubate with salt stress.

Thus, to increase the value of the product of the ice plant it is desirable to continue to give the stress caused by salt, but excessive stress to promote the flowering, so the stress must be well controlled. This is because, with salt concentration, growth slows (weight loss), CAM phenomenon begins to appear, stems and leaves begin to wither, and all nutrients are used as energy sources for flowering.

According to the present invention, the harvest of the ice plant is possible after about 80 days after sowing, the average weight is about 200g ~ 250g. The tasting part is about 90 ~ 100g, because the size of the leaves in the ice plant is large because the weight of the stem and young leaves that can actually eat.

If the nutrient growth stops for about 90 days, the flowers begin to bloom, and during flowering, it is important to harvest before flowering because there is no spot to eat.

Hereinafter, the content of the present invention will be described in more detail with reference to Examples. However, these examples are only presented to understand the content of the present invention, and the scope of the present invention should not be construed as being limited to these embodiments.

Example 1 Cultivation of Ice Plant by Salt Concentration Control

After preparing the germination plug and planting one or two seeds of the ice plant, they were covered with a thin layer of about 1-2 mm from the seed so that the seeds were hidden. Then, after sowing, water was carefully sprayed using a sprayer.

Germination took place one week after sowing, and if more than two germinated, germination was performed before planting. The germination temperature was 24 ℃, humidity was maintained at 50%.

When the leaves became 3 to 4 sheets, and the total size became about 2 cm after 20 days after sowing, the planting was performed at 50 cm intervals. Fifteen days after the establishment, less than 0.5 ~ 2% (w / w) of salt water was prepared by concentration and sprinkled on the root side.

As shown in Table 3 below, salts were added to the roots at different concentrations for the ice plant 100 individuals, and the CAMization according to the salt concentration was measured 30 days after sowing, and the weight of the ice plant 80 days after sowing was measured. The measurement results are shown in Tables 3 and 4, respectively.

In the embodiment of the present invention harvesting was carried out after 80 days after sowing, the average weight was about 200g ~ 250g. The tasting part was about 90-100 g.

Example 2 Cultivation of Ice Plant Under Salt-Free

In order to increase the content of the functional material of the ice plant, it is necessary to stress within a range that does not occur CAM. According to this embodiment, as in Example 1, it was confirmed that the content of the functional substance may be increased by giving stress by environmental factors other than stress through salt control.

In this example, the component analysis was performed on the content of the functional substance by adjusting the temperature factor of the ice plant. Experiments on the temperature conditions were carried out for each growth stage, and the contents of the functional materials were investigated and the results are shown in Tables 5 and 6 below.

Table 5 is a result of analyzing the content of the functional material proceed to the conditions of the existing cultivation environment 20 ~ 25 ℃, Table 6 is a result of analyzing the content of the functional material proceeds to the conditions of 26 ~ 34 ℃. At this time, the salinity and humidity during the cultivation, the culture was carried out under the same conditions. In addition, the experiment was carried out under the temperature conditions of Table 7 in consideration of the fact that the daytime temperature of the desert is usually 32 ~ 42 ℃, the maximum temperature of about 54 ℃ to confirm the CAM phenomena.

* Normal state: N (normal), CAMization: C

As can be seen from the above cultivation results, the cultivation at a higher temperature than the existing temperature was found to increase the content of the functional material. If CAMization occurs during cultivation at high temperature, it is important to set the temperature within the normal range for 1 ~ 2 days to eliminate CAMization. In particular, the CAM phenomenon is prominent above 34 ° C., and therefore, it is not suitable for cultivation for food.

As described above, it has been described with reference to a preferred embodiment of the present invention, but those skilled in the art various modifications and changes of the present invention without departing from the spirit and scope of the invention described in the claims below I can understand that you can.
