PROBLEM TO BE SOLVED: To provide natural plant activating liquid obtained by the fermentation treatment of seaweed which is difficult to be liquefied.SOLUTION: Sawdust, cow dung, rice bran, lime and seaweed are fermented and the seaweed is dissolved to produce liquid, the liquid is repeatedly agitated for fermentation, and finally water is added to poultry manure for boiling and supernatant thereof is mixed for full maturity fermentation, thereby obtaining natural plant activating liquid.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】液体化するのに難かしい海藻を発酵処理して得た天然植物活性液の提供。【解決手段】オガクズ・牛糞・米糠・石灰・海藻を発酵させて海藻を溶かして液体を生成し、この液体を攪拌を繰り返して発酵させ、更に最後に鶏糞に水を加えて煮沸しその上澄み液を混ぜ完熟発酵させて得た天然植物活性液。【選択図】図1
