After rice seeds has put out, they are sowed on soil. Sowing rice seeds has lots of progress and hard to deal with just like the sprouting work.
Rice farmers use plastic plates, Naebako in Japanese (なえばこ in Hiragana) which has many small holes at the bottom so that water comes out from them, when they sow rice seeds.
Rice sowing is divided into 3 stage of work mainly, and the work makes 3 layers in the Naebako.
First of all, fertilizer is spread thinly on every Naebako using special tool to flatten the surface like a ruler, and then disinfectant liquid which is watered down is spread using watering can.
Secondly, rice seeds are sowed by a machine. This work can be done by hand, but it is hard to sow rice seeds equally by human hands.
Finally, soil with no fertilizer is spread quickly on the seeds, and surface must be flat again. After that, whole Naebako need to be infiltrated disinfectant liquid.
They are brought up in a greenhouse about one month till it grows about fifteen centimeter.
This is all sowing progress. It seems to be simple work, but very tough actually. People who flatten the soil have to bend the waist long time, and Naebako especially, with moisture is so heavy to convey.
In my grandfather’s farm case, there are 240 Naebako, so my family did the above work for 240 times…
