Description

[Detailed Description of the Invention] This invention is a method for cultivating Ashitaba, which is characterized by sowing seeds between trees having root nodules and collecting Ashitaba, which contains large amounts of vitamin B group and vitamin E, by the action of the root nodules. It is related to.

The Ashitaba of this invention mainly grows naturally in the southern part of the Izu Peninsula, Oshima Island, Hejo Island, etc. Eating its leaves and stems is said to be beneficial for health, and the local people eat them for food. Its cultivation is said to be extremely difficult, and cultivation on a commercial scale has never been attempted.

Trees with root nodules used in the present invention, such as alder, are known as land improvement trees for cultivating soil, sandy soil, barren soil, etc., as they are useful for maintaining and increasing soil fertility. has not yet been fully elucidated.

This invention is based on the above-mentioned knowledge and conducted various research on the relationship between trees with root-knot roots and Ashitaba, and found that when seeds are sown between trees with root-knot roots and grown, they contain significant amounts of vitamin B group and vitamin E. After learning that rich Ashitaba can be harvested through cultivation, he developed this invention.

It is thought that the soil fertility of the root nodule is increased by the fixation of atmospheric nitrogen, but the content of vitamin B1□ in the root nodule has not yet been investigated.

However, the stems, leaves, etc. of Ashitaba sown and propagated between these root nodules contain large amounts of vitamin B group and vitamin E, and have excellent uses as raw materials for highly nutritious processed foods. It is.

The following table shows the analytical test results of the leaves and stems of Asitaba cultivated according to the present invention and the leaves and stems of naturally propagated Asitaba.

The cultivation conditions for Ashitaba according to the present invention are that trees with root knots (alders) are planted at 10 meter intervals, a 10 cm high ridge is created between them, and 30 trees are planted at 30 cm intervals. Plant Ashitaba,
It was cultivated for three years.

As is clear from the above analysis table, the Ashitaba cultivated according to the present invention has 4.5% of vitamin B1 compared to the naturally bred one.
57 times, B2 is 3.7 times, B6 is 10.17 times, B1□
contains 0.32 compared to 0 for naturally bred, and vitamin E has been shown to be increased 16.8 times.

In addition, the above-mentioned effect of increasing vitamins is observed when the distance between trees having root nodules is set at 5 meters to 12 meters, and when Ashitaba seeds are sown between these intervals.

Vitamin B group has an excellent effect on recovering from fatigue and promoting health, and recent research shows that vitamin E is an antioxidant vitamin that suppresses the oxidation of unsaturated fatty acids in the body, which causes aging phenomena. It has been announced that it inhibits the formation of fatty acid peroxides and proteins, and also prevents pigmentation in cells such as visceral tissues, nerves, and adrenal glands, and has a remarkable anti-aging effect. There is.

Next, to describe one embodiment of this invention, ridges of about 10 centimeters in height are made between alders planted at intervals of about 5 meters, and around the end of February they are planted at intervals of about 30 centimeters to prevent dense growth. Sow Ashitaba seeds.

The seeds began to germinate about 10 days after sowing.

Ashitaba is perennial.
It grows to about 50 centimeters, but after that it is naturally cultivated.

Then, when the lower leaves of Ashitaba come into contact with the ground,
Trim this and let it air out.

Also, if you try to give it half a day of western sunlight rather than eastern sunlight, it will grow well and flowers will bloom around the end of August, and seeds can be harvested until mid-September.

In short, as mentioned above, this invention succeeded in cultivating Ashitaba, which was thought to be impossible to cultivate in the past, and by using trees with root knots, it has a nutritional value that contains large amounts of vitamin B group and vitamin E. This method enables the successful collection of a new variety of Ashitaba with high quality, and has great technical and economical effects as it enables mass production.
