PURPOSE:To actively grow a plant by making it absorb respective proper amounts of nutrients and oxygen. CONSTITUTION:Part of the roots of a plant is put into a liquid nutrient feeding element 14 and immersed in the liquid nutrient to selectively make this portion absorb the nutrients in the solution, and air and nutrient-contg. fume are fed to a duct 13 using a spraying machine 2 and a blower 3 to make this portion absorb oxygen sufficiently and enhance microbial activity at this portion, thus protecting the plant from growth impairment or disease injuries due to improper nutrient absorption and insufficient oxygen absorption. |
