薬を使わず元気で丈夫な苗をつくるには、種籾の塩水選から始めます。
塩水選とは、元気な種籾を選別する方法です。種籾が塩水で「浮く」「沈む」で選別します。
For growing the healthy and strong seedlings without using chemicals, start with salt water selection for the rice seeds.
The salt water selection is a method of sorting out healthy rice seeds. The seed is sorted out by “floats" or "sinks" in salt water.
POINT１「塩水選」
【Salt Water Selection】
①塩水を作る。
井戸水(10L)に対して 塩(1.5kg～2.1kg)を大きめのポリバケツに入れて混ぜる。
※濃度を調べる方法は､生卵を静かに沈め､途中まで沈んで浮き上がって､先端が少し出るくらいが目安です。選別用の塩水計も使えます。
1. Make the salted water.Mix salt (1.5kg-2.1kg) into well water (10L) in a large plastic bucket.*How to check the concentration is using an egg. Put the egg gently into the solution.
The egg should sink and then float up and the tip is slightly above the water surface. Another way is that using a salinity meter for selection.
②①で作った塩水に種籾を入れ､浮いた種籾は、取り除き、沈んだ種籾のみ取り出す。
(元気で丈夫な種籾)
2. Put the rice seeds into the salted water which we made in step 1.Remove the floated seed, collect and use only the sinking seeds.
(they are the healthy and strong seeds).
③②で沈んだ種籾をザルに入れ､井戸水で洗い､かけ流しで､3～4回洗う。
3. Put the seeds that sank in step 2 into the strainer, wash then with well water, and rinse then 3-4 times with flowing water.
④③で洗った種籾を更にザルにあけて、水をきる際に塩気がないかザルから落ちる水を手に取り舐めて確かめる。少しでも塩気がある場合は、もう一度洗って完全に洗い直す。
4. Pour the washed seeds from step 3 into the strainer again. Taste to check the dipping water from the strainer if there is any saltiness remaining. If the water tastes saltiness, wash it again.
⑤種籾を１㎏ずつ、袋に入れる。
これで選別はOK！

5. Put 1kg of seeds into each bags.
Now complete the selection!
Next time, we will introduce “hot water disinfection” without using chemicals!
