SubjectThe object of the present invention is to provide a paddy field fertilizer bag which is easy to install in a paddy field.SolutionThe bag for paddy rice fertilizer is composed of four sides of a rectangular bag and a second bag composed of a nonwoven fabric, one side is sewn by a non warm water soluble thread, and the other three sides are sewn by a hot water soluble thread and a non warm water soluble thread, and the paddy rice fertilizer is sewn in the paddy fertilizer Powder fertilizer is contained in the bag.When the bag body of the paddy field fertilizer containing the powder fertilizer is placed near the water mouth, the irrigation water penetrates into the paddy rice fertilizer bag through the permeable nonwoven cloth, and the bag body of the paddy fertilizer is shaken by the fluctuation of the irrigation water flow, and the powder fertilizer is It becomes a mold in the clay shape while heating.On the other hand, since the hot water soluble yarn is dissolved with the lapse of time, the bag for paddy rice fertilizer is dissolves and is formed into a single sheet shape from the bag shape, and the fertilizer which becomes the clay like lump is directly exposed to the irrigation water, and the elution is promoted, and it is uniformly diffused in the whole paddy field.Diagram【課題】 本発明の目的は、水田への設置が容易である水田肥料用袋を提供することである。【解決手段】 水田肥料用袋は、不織布からなる矩形の第1袋構成体と第2袋構成体の4辺の内、一辺が非温水溶解性糸によってミシン縫製され、他の3辺は温水溶解性糸及び非温水溶解性糸によって縫製されて構成され、当該水田肥料用袋内には粉体肥料が内包される。当該粉体肥料が内包された水田肥料用袋体を水口の近傍に設置すると、透水性の不織布を通って灌漑水が水田肥料用袋内に浸透すると共に、灌漑用水流の揺らぎによって水田肥料用袋体が揺らされることにより粉体肥料が発熱しつつ粘土状に塊となる。一方、時間経過と共に温水溶解性糸が溶解するので水田肥料用袋は、縫合が解かれて袋状から一枚のシート状になり、粘土状塊となった肥料が灌漑用水に直接曝されて溶出が促進され、水田全体に均一に拡散される。【選択図】図1
