PROBLEM TO BE SOLVED: To solve the problem with applying liquid fertilizer to plants wherein the operation of mixing and adjusting water and liquid fertilizer in a bucket or the like before applying to plants is hard regardless of its very quick effect.SOLUTION: This simple liquid fertilizer mixer that makes the mixing ratio of liquid fertilizer and water adjustable is installed between a water sprinkling nozzle and a hose in a single operation. The mixer creates a pressure difference by limiting the amount of tap water flow, thereby causing an original solution to be pushed out by the same amount that it enters a container and to flow into main flow, and mixing water and the original liquid fertilizer solution. The liquid fertilizer mixer has a transparent container, which is filled with the original liquid fertilizer solution to allow the concentration of the original solution to be known by its color to some degree, to indicate the time for replenishment. When the original solution and water are mixed, the original solution remains at the bottom because of its higher specific gravity, while water that enters slowly remains at the top of the container, so the preset mixing ratio is maintained. The original solution is directly poured into the container of the mixer and the fertilizer can be applied while a water solution diluted as desired is in the same condition as for normal water sprinkling.【課題】液肥を用いて植物に施肥する場合、その即効性は抜群であるにも関わらず、バケツ等に水と液肥の混合調節してから植物に与えている。その作業は大変なものである。【解決手段】液肥と水の混合比を調節可能な簡易液肥混合器を散水ノズルとホース間にワンタッチで取り付ける。混合器は水道水の流れの量を制限する事により差力圧を作り、容器に入り込んだ分だけ原液が押し出され本流に流れ込み、水と液肥原液が混合される。液肥混合器には透明な容器があり、その中に液肥原液を入れ、原液の濃度をある程度色で判別出来、補充の時期を知る事が出来る様になっている。原液と水の混合は原液の方が比重が重いので下側に滞り、じっくりと入る水は容器の上側に残っているので最初の設定された混合比がそのまま続いている。混合器の容器に原液をそのまま入れ、希望通りの希釈された水容液を、通常の散水をする状態と全く変わらない状態で施肥出来る。【選択図】図２
