Abstract: In order to explore the nutrient solution concentration on the quality of products,water spinach,water and fertilizer use efficiency and effect.This paper plant factory hydroponic spinach experiments to Japanese garden tries the formula nutrient solution as a reference standard,set 1,3/4,1/2,1/4,1/8 times different concentrations on yield of spinach,quality,nutrients use efficiency,water use efficiency. The results showed:1/2 times concentration garden tries the formula yields significantly higher than other treatments;1/8 times significantly lower concentrations of nitrate,1 double,3/4 times,nitrate 1/2 times exceeded national treatment under standard,1 double,Vc content of 3/4 times treatment was significantly higher;water use efficiency of nutrient solution processing was 1/2 times the highest concentration of the element efficiency at low concentrations generally high;principal component analysis by synthesis evaluation of the highest scores of the top three were:1/8,1/4,1/2 times concentration,respectively 1.600,1.544,1.541 score.

Key words: Nutrient solution, Spinach, Concentration, Efficiency, Quality
