The cultivation method of Japanese radish

The place of origin of a Japanese radish is the Mediterranean. This likes cold and cool environment. However, since there are various improved-goods kinds, cultivation during about one year is possible. Resistant to cold, so the optimum temperature 17-20 degrees C growth, autumn sowing would be easy to make.

Making the ground for Japanese radish cultivation

Japanese radish If a compost is put in, what attained full maturity of one month or more before sowing is put in, or a compost is put on the surface with an additional fertilizer. If it is acid soil, lime and calcium cyanamid are scattered. Dig a trench to put the base fertilizer 1-2 weeks before the ridge. It cultivates deeply once and removes a pebble, garbage, etc. A stone and garbage become a cause by which a Japanese radish branches or a form becomes distorted.

It seems that the place of production of a Japanese radish has much land of volcanic ashes. Isn't this because it is the ground like fine ashes with few pebbles in volcanic ashes? It may be better to sift the ground once and to remove a pebble and sand, if a Japanese radish is continued and grown.

The sowing method of Japanese radish

It plants 4-6 grains of kinds of Japanese radish at a time. It presses down lightly, covering the about 1-cm ground, and sticks the ground for a seed. Then, water is given fully. It is made not to dry the ground until it buds.

Infanticide, Cultivation, Weeding out, Additional fertilizer

If a true leaf will be 3-4 sheets, it will thin out so that it may become 2-3 at one place. Let's make the ground flat after thinning out. If a true leaf will be 5-6 sheets, finally one will be used. Growth leaves what has a good and good form.

Let's bring near the ground by stock origin at any time. The white portion of a Japanese radish is kept from coming out on the ground as much as possible. If a Japanese radish comes out of the ground, it will become blue and the taste will worsen. I think that it is good to bring near the ground while cultivating or weeding out.

A liquefied fertilizer and compound fertilizer are used for the additional fertilizer of a Japanese radish. Let's make early extermination of the plant louse of a noxious insect, a diamondback moth, etc. In order to reduce the damage of a noxious insect, a nonwoven fabric is hung or an insect control network is made into the shape of a tunnel.

Harvest of a Japanese radish

A Japanese radish comes out in a ground part, and a harvest will be gathered if thickness also becomes large. It draws out upwards straight firmly with stock origin. If it pulls on width or slant, a Japanese radish will break. If a harvest is gathered late, a core may be made or the surface may break.

About collaboration of a Japanese radish

Although Japanese radishes are the vegetables out of which the obstacle of repeated planting cannot come comparatively easily, a root wen disease, a soft rot, etc. common to a brassica family may be caused. Generally, it says that it is better not to grow the vegetables of a brassica family at the same place one to two years.

However, if a Japanese radish is planted a field with the same crop every year in the same field, its pungent condiment ingredient decreases gradually and it has the character to become sweet. Please decide whether plant a field with the same crop every year after seeing the state of a field, and the situation of the harvest of the previous year. What are failure and experience.

Winter firewood cultivation of a Japanese radish can be carried out by tunnel cultivation.

If a flower bud will be made if temperature will be 10 ℃ or less, and a Japanese radish becomes warm, a flower will bloom and a core will be made.
If it sows in winter for the reason, hypertrophy of a root will stop, before gathering a harvest. Then, if it grows in a vinyl tunnel or a greenhouse, it can take in the spring of winter cultivation, and can make a Japanese radish. If black multi is made a trough, growth is rash and it can stop weeds.

Even if it is tunnel cultivation, temperature will be 0 ℃ or less at night. however, since daytime comes high temperature, it obtains up and does not carry out, without the ability of the Japanese radish to do a flower bud.
