Description

Method for cultivating dandelion using mixed media of cocopeat and perlite in plastic house}

The present invention relates to a cultivation method of dandelion, characterized in that it is cultivated using a mixture of cocopeat and perlite (perlite), the dandelion cultivated by the method of the present invention growth such as leaf area and underground live weight Can improve.

Dandelion is a herbaceous plant, and is a perennial plant of Asteraceae. The whole plant, including roots, leaves, flowers, and flower stalks, is used for medicinal purposes, and about 2,000 species are distributed throughout the world including Korea. In Korea, there are mainly Taraxacum mongolicum , T. hallaisanense , ( T. ohwianum ), T. coreanum , and T. officinale and T. laevigatum two naturalized species.

Dandelion is rich in vitamins and minerals, low in fat content and low in calories, suitable as a well-being food, and contains taraxin, inulin, caraxenoids, taraxathin, Vitamin A, vitamin C, tocopherol, calcium (Ca), catecholamine (catechol), and triterpene (taraxerol), taraxasterol, ), Iron (Fe), potassium (K) and so on.

Dandelion hydrothermal and ethanol extracts have antioxidant activity (Shahidi et al., 1992), hydroxyl radical scavenging activity (Kang, 2001), and antimicrobial activity against food poisoning bacteria (Kim et al., 2000), but there is no such effect on useful kimchi fermentation strains (Kim et al., 2000), although there is antimicrobial activity against the staphylococcus causing inflammation and inhibition against skin fungi . (Baba et al., 1981) and have strong anticancer activity against sarcoma 180 solid tumors (Kim, 1995). In addition, it is known that it has an effect of improving the body's lipid metabolism (Cho et al., 2000) and anti-inflammatory effect (Kim, 1991) Fermented beverages, and so on.

In addition, Ho et al. (1998) reported that the desacetylmatricarin component of the ethanol fraction of the dandelion fraction had anti-allergic activity Respectively.

In order to make dandelion practical for plant cultivation, the growth reaction of dandelion according to the degree of shading and the nutrient solution with different conservative, fertilizing and breathability is expected to be different. Indeed, shading is not only the effect of lowering the brightness, but also the geothermal and plant temperature (Brand, 1997), but under excessive shading conditions, the decrease in net photosynthesis results in a decrease in nutrient growth, grass length, geodetic index, leaf length, leaf area and dry weight. It is reported to adversely affect the yield (Son & Chae, 2003; Brand, 1997; Hong et al., 1996). Lee et al. (1998) found that the changes in the composition and essential oil components of Deodeok by shading treatment decreased crude protein and crude fat as the degree of shading increased, whereas trans- 2-hexanol, which is a fragrance component, was 3.2 times higher than that of no shading. Reported loss. However, there have been no studies on the growth and content of bioactive substance or its activity by the degree of shading.

Korean Laid-Open Patent Publication No. 2007-0004339 discloses a fertilizer composition for leaf vegetable hydroponic cultivation and a method of using the same, and Korean Laid-open Patent No. 2008-0069792 discloses a method for producing a herbal nutrient for vegetable cultivation and a vegetable cultivation method using the nutrient. However, it is different from the cultivation method of dandelion using the mixed cocoite and pearlite medium of the present invention.

The present invention has been devised by the above-mentioned demands, and in the related art, suitable medium and environmental conditions for cultivating nutrient solution for dandelion have not been established. It is to develop a method of cultivating dandelion using the condition and using it.

In order to solve the above problems, the present invention provides a cultivation method of dandelion, characterized in that the cultivation using a mixture of cocopeat and perlite (perlite).

Dandelion cultivated in the medium and environmental conditions of the present invention can increase the leaf area and underground live weight, thereby improving the growth, thereby reducing the cost as well as increasing the productivity has the effect of improving the farm income.

The nutrient solution composed of the composition ratios as shown in Table 1 was supplied at a rate of 1/2 times (EC, 1.1 dSm ^-1 ) at the beginning of growth, and adjusted to a standard concentration (EC, 2.2 dSm ^-1 ) after the middle of growth.

Dandelion seeds were sown at intervals of 15 cm x 20 cm in July 2009, and the test zones were placed in three repeats of the random placement method. Water was supplied for one week after sowing, and nutrient solution was supplied from the second week. 100 mL of each plant was acyclic for 15 minutes from 10 am to 4 pm using a timer based on the standard nutrient solution from the Japanese Horticultural Testing Laboratory. Supplied. During the test period, the average daily light intensity (PAR) in the house was 134.7 μmol photons m ^-2 s ^-1 , which was lower than the external average brightness of 963.9 μmol photons m ^-2 s ^-1 . Medicinal plant cultivation practices were followed.

Example  1: Determination of Chemical Properties of Medium

The chemistry of the medium was pH (superelectrode method), EC (electrical conductivity), organic content (Tyurin method), P ₂ O ₅ (Lancaster method) and potassium (K), calcium (Ca), magnesium (Mg), sodium (Na ), And the cation substitution capacities (CECs), which represent macroelements, cation content, and fertility, were analyzed according to the soil chemical analysis method (Rural Agricultural Research Institute, 1989).

* The same alphabet in the column means no statistical significance.

As can be seen in Table 5, leaf area was the highest in the medium mixed with cocoite and pearlite 50:50 and 70:30. However, chlorophyll content did not show a significant difference by medium. In addition, according to the degree of shading, cultivation without shading showed the highest chlorophyll content and leaf area significantly (FIGS. 3 and 4).

* The same alphabet in the column means no statistical significance.

As can be seen in Table 6, the above-ground live weight was the lowest in the cocoite alone medium, and was high in the medium mixed with cocoite and pearlite at 50:50 and 70:30. Underground biomass also showed similar trends. In addition, according to the degree of shading, the shade-free cultivation showed a significantly higher ground and underground live weight (FIGS. 5 and 6).

This tendency resulted in different conservatism, binding, and breathability for each media combination. Especially, the difference in the composition of the medium caused the growth of dandelion due to the highest growth in the medium mixed with cocoite and pearlite at 50:50 and 70:30. It was found that it is reflected in the reaction as it is. As the growth of dandelion grown in the light-shielding condition in the shading condition is improved, it can be seen that it is preferable to cultivate without shading when growing dandelion.
