★５年！バケツ稲！中干し！（2019/07/09）

５年生！
人と環境の学習です！
５年生では，バケツでイネを育てています。
先日，バケツの中の水をすべて出して，土を干す作業をしています！
この作業を中干しといいます。
この作業は，バケツ稲だけではなく，一般の田んぼでもします！
この作業で，土の中に，空気中の酸素を取り込みます！
また，根をしっかり張らせて，丈夫な稲にします！
稲の生長にとって，この中干しという作業は，とても重要な作業です！
稲の様子を見て，今週末まで，中干しをしようと思います！

5th graders !
Learning about people and the environment!
The 5th graders are growing rice in buckets.
The other day, all of the water was dried.
This is a process called "Nakaboshi"
This process is not just for rice in a bucket, but is also used on normal rice fislds.
Through this process, the soil is aerated, allowing oxygen to enter.
Additionally, aeration of the soil helps the roots of the rice plants push through the loosered soil grow stronger !
The Nakaboshi process is very important for the growing of rice !
After inspecting the rice,we've decided to do Nakaboshi until this weekend !
