Abstract
In order to select the best nutrition formula suitable for greenhouse hydroponic growth in the north of China,using the floating plate test method of breeding,4 different nutrition formula were used to conduct endive hydroponic cultivation.The endive leaf number,plant height,fresh weight and root shoot ratio of different concentration of nutrient solution treatments were investigated.The results showed that the leaf number and fresh weight of formula B was lower than the other formulas,A,C and D formula had no significant difference,but D formula was superior to A and C formula in the leaf number,plant height and fresh weight.Therefore,A,C,D formulas were all suitable for greenhouse hydroponic cultivation,especially the D formula,and B formula was not suitable for greenhouse hydroponic cultivation.关键词
