To provide a surface layer suction leaching device for removing a large amount of salts by a small amount of water, from salts-accumulated soil, without letting salts accumulated on a soil surface layer flow into lower layer soil, or collecting soil in place, free from the need of troublesome regenerative work, and removing salts inexpensively, and to provide a method for suction leaching a surface layer.例文帳に追加

土壌表層に集積した塩を下層土壌に流下させることなく、原位置にて土壌を採取することなく、少量の水で多量の塩類を塩類集積土壌から除去することができ、面倒な再生作業を必要とせず、さらに安価に除塩できる表層吸引溶脱装置および表層吸引溶脱方法を提供すること。 - 特許庁
