Comprehensive Evaluation for the Effect of Ammonium and Nitrate Ratios on Chinese Kale Quality
In hydroponics conditions,four different ammonium and nitrate ratio treatments (CK,0∶ 100;T1,10∶90;T2,25∶75;T3,50∶50) with equal nitrogen concentrate were set to study the effect on the growth and quality of Chinese kale.Using the principle of fuzzy mathematics and analytic hierarchy process,a comprehensive evaluation of the quality of Chinese kale was determined.The results showed that,compared with the control (CK) treatment,T1 treatment promoted the growth of Chinese kale,but had no significant effect on the quality;T2 treatment got the highest yield,but had no significant effect on quality;T3 treatment got the highest quality,but plant growth was inhibited.The T2 treatment of appropriate enhancement of ammonium was optimal for the comprehensive quality.Fuzzy comprehensive evaluation based on analytic hierarchy process for quality comprehensive evaluation in Chinese kale had good applicability.
