山中式土壤硬度計 Yamanaka’s soil hardness tester 山中式土壤硬度計是測式土壤硬度儀器,是日本山中博士經過十多年研究,最初目的是測量日本農田經農用機械走過後,研究田間土壤被壓實的情況。 日本樹木醫普遍使用,山中式土壤硬度計最大好處是好攜帶,但只能測土壤表面,如果要知道土壤斷面的話,只能挖一個大洞,放一把尺,一個個深度去測量。 原理是長度4公分的圓錐體,後方是一個彈簧,和土面接處,土壤愈硬,圓錐愈退後,讀值愈高。 資料來源file:///C:/Users/ASUS/Desktop/%E5%B1%B1%E4%B8%AD%E5%BC%8F%E3%80%80082560%E3%80%80%E5%8F%96%E8%AA%AC.pdf
