Effect of Nutrient Solution with Different Concentration on Growing Adaptability of Chinese Chive under Water Culture Condition
摘要
Abstract
In order to find appropriate nutrient solution concentration under water culture condition for Chinese chives and study its effect on the growth,yield and quality,5 levels nutrient concentrations(0.5 C、1.0 C、1.5 C、2.0 C、2.5 C)were set up on normal nutrient solution base.The results indicated that the plant height,leaf length and width,number of leaf blade,cauloid thickness and root activity indexes all showed the tendency of decreasing first then increase.While,vitamin C,soluble sugar,soluble protein,etc.quality indexes increased first then decreased.Nitrates and nitrite concentration of 0.5 C were the highest.The yield of Chinese chives treated by 0.5 C was the highest reaching 73.86 t·hm-2,and the contents of nitrate and nitrite were the lowest.Thus,0.5 C is the appropriate nutrient solution concentration for Chinese chives under hydroponic culture.关键词
