2 差込体
3 硫化水素濃度確知用指標色表示具
Claims (3)
- 水田土壌中の硫化水素の発生の有無を検知すると共に、硫化水素が発生していた場合、その水田土壌中に発生している硫化水素の濃度を確知することができる水田土壌用硫化水素検知装置であって、水田土壌に差し込み可能な差込体と、前記水田土壌中に発生している硫化水素の濃度を確知するための硫化水素濃度判断用指標色表示具とからなり、前記差込体は、表面全体に銀メッキが施された帯板状に形成された基体からなり、水田土壌中に硫化水素が発生していた場合その硫化水素と反応して水田土壌差し込み部分が変色するように構成され、前記硫化水素濃度判断用指標色表示具は、前記差込体を前記水田土壌に差し込んでいた時間別の硫化水素濃度を判断するための複数の指標色群が表示されている構成とされていて、前記水田土壌に差し込んだ差込体の表面の変色の有無により前記水田土壌中の硫化水素の発生の有無を検知すると共に、硫化水素が発生していた場合、前記硫化水素濃度判断用指標色表示具に表示された前記指標色の中の前記差込体を前記水田土壌中に差し込んでいた時間に対応する指標色群と、硫化水素により変色した前記差込体を照合することにより、前記水田土壌中に発生している硫化水素の濃度を確知することができるように構成されていることを特徴とする水田土壌用硫化水素検知装置。
- 前記差込体は、上部にこの差込体を水田土壌に埋設した際に水田土壌より露出させこの差込体の埋設位置を見失わないようにするための目印部が設けられていることを特徴とする請求項1記載の水田土壌用硫化水素検知装置。
- 水田土壌中の硫化水素の発生状況を確認する方法であって、表面全体に銀メッキが施され水田土壌に差し込み可能な帯板状に形成された基体からなり、水田土壌中の硫化水素と反応して水田土壌差し込み部分が変色するように構成されている差込体を、水田土壌中に差し込み、所定時間経過後、前記水田土壌から前記差込体を抜き取り、この差込体の前記水田土壌に差し込んだ部分が変色しているか否かを目視確認し、前記水田土壌に差し込んだ部分に前記変色が見られた場合、前記水田土壌中に硫化水素が発生していると判断すると共に、前記差込体を前記水田土壌に差し込んでいた時間別の硫化水素濃度を判断するための複数の指標色群が表示されている硫化水素濃度確知用指標色表示具を用い、この硫化水素濃度判断用指標色表示具に表示された複数の前記指標色群の中の前記差込体を前記水田土壌中に差し込んでいた時間に対応する指標色群と、前記差込体の変色後の色とを照合して、前記水田土壌中に発生している硫化水素の濃度を確知することを特徴とする水田における硫化水素の発生状況確認方法。
