In the present invention, in the cultivation of crops such as cucumbers, peppers, tomatoes, lettuce, etc., the fertilizer to be sprayed to the mixing tank and dissolved in the liquid fertilizer by the raw water supplied by supplying the raw water through the water heater inside the mixing tank ( Liquid fertilizer) by spraying the crops, increasing the dissolved oxygen of the raw water supplied into the mixing tank, and also increasing the dissolved oxygen contained in the liquid fertilizer to be supplied by causing the supplied raw water to vortex in the mixed tank. The present invention relates to a liquid fertilizer mixing device of environmentally friendly farming methods to replenish the soil with insufficient oxygen and to supply oxygen as well as fertilizer for crops.

Crops that often come to our table, such as cucumbers, peppers, tomatoes, lettuce, etc., absorb the oxygen from the roots and release carbon dioxide through the leaves to achieve the energy metabolism necessary for the growth of the crops. This planted soil should contain sufficient oxygen.

However, during the cultivation of crops, not only the growth rate of the crop is increased, but also various pests or white powder diseases (white powder): the diseased areas are warped in a ugly shape, wilting leaves or stems, and the fruit quality is poor. Chemical fertilizers are sprayed on the planted soil to protect the crops from those that hinder the growth of crops such as anthrax, anthrax, pestilence, rot and navel rot.

The chemical fertilizer sprayed in this way helps protect the crops from the aforementioned diseases, but the chemical fertilizer spreads into the soil as it is, so that the dissolved oxygen content in the soil is significantly reduced. .

That is, fertilizers applied to the soil where the crops are planted are dissolved in rainwater and absorbed into the soil and supplied to the crops through the roots of the crops, for example, when there is no frequent rain or when the fertilizer applied to the soil is completely dissolved. In this case, the dissolved dissolved fertilizer is absorbed into the soil as it is, so the amount of dissolved oxygen contained in the soil is reduced by reducing the amount of dissolved oxygen remaining in the soil so that the amount of oxygen necessary for the growth of the crop is not contained in the soil. If it decreases, the amount of oxygen, which is essential for the growth of crops, becomes insufficient and accordingly, the amount of oxygen absorbed by the roots is insufficient. Eventually, the roots suffocate and adversely affect the growth of crops.
