Chinese Cabbage（Nagano prefecture）

Aiming to increase L-size and reduce loss ratio

・The best thing to do is to increase the number of L-size plants. This would increase the unit yield.
・I want to reduce the loss ratio.
・For Chinese cabbage to grow large, it is important that the white eating part grows large. Since the tuber cannot photosynthesize, it uses photosynthetic energy from the outer leaves. Therefore, the growth of the outer leaves is important.

Why did you install Nanobubble?

・I would like to reduce the loss ratio and increase the L ratio since the M ratio is high.
・Because of heavy rainfall and black spot disease, I tried to introduce the system to reduce the disease.

How was the effect of Nanobubble? (1st year)

・Recently, the ratio of 2L and L size increased due to better ball growth with nanobubbles.
・Comparison of Chinese cabbage size (about 1 反)
With nanobubbles: 2L=5% L=80% M=15
Control: 2L=0% L=70% M=30
・Differences with nanobubbles
The balls were larger and heavier. Also, the leaves became thicker. (It is said that the bigger the Chinese cabbage, the better)
・Black spot disease was also observed both with and without nanobubbles, but the leaves of those with nanobubbles were healthy and the balls grew. Many M-size plants without nanobubbles stopped growing. To be honest, I was surprised because I did not expect such a big difference!

How was the effect of Nanobubble? (2nd year)

In the second year, due to the long rainy season, NB could hardly be used and the effect was hard to see. However, when comparing actual Chinese cabbage, the difference was obvious. The size and firmness of the balls were completely different!

How was the effect of Nanobubble? (3rd year)

Without nanobubbles, the ratio of LM to cardboard boxes is 60% L and 40% M for 100 cases. With nanobubbles, the ratio is about 90% L and 10% M.
There are many L’s and there are differences, although the disease can’t be helped.
I know without a doubt that oxygen is good for the roots. However, the silver ion solution tended to be too effective and caused chemical damage. However, we were able to see a difference in the size of the plots with and without nanobubbles in the actual harvest.
The hypothesis is that the outer leaves of the nanobubble zone were firm. This may be due to the fact that the nanobubble water ensured sufficient water content at the time of tuberization, when the water requirement increases.
