Effects of Liquid Amino-Acid Fertilizers on Yield,Quality,and Nitrogen Use Efficiency of Greenhouse Tomatoes
摘要
Abstract
This study investigated the application effects of liquid amino-acid fertilizers on greenhouse tomatoes,aiming to establish an efficient,low-pollution,eco-friendly and high-quality tomato production system.Four ex-perimental treatments were designed:no nitrogen fertilizer application(CK),conventional nitrogen application(T1),and three treatments supplemented with different liquid amino acid fertilizers on the basis of conventional nitrogen fertilization,including medium-element type(T2),trace-element type(T3)and polypeptide type(T4).The effects of various liquid amino-acid fertilizers on the yield,fruit quality,nitrogen uptake and utilization of greenhouse tomatoes were explored.The results showed that for yield parameters,fruit number,single fruit weight and yield of treatments with additional liquid amino-acid fertilizers were slightly higher than those of T1,and significantly higher than those of CK.Compared with CK,the yield increased by 15.29%-18.60%,while compared with T1,the yield rose by 7.43%-10.51%.T2 achieved the maximum values for all yield-related indices.In terms of fruit quality,the nitrate content in fruits of amino-acid fertilizer treatments was signif-icantly lower than that of CK and T1,with T2 recording the minimum nitrate concentration.There were no significant differences in titratable acid con-tent between amino-acid fertilizer treatments CK and T1.However,the contents of Vc,soluble solids,sol-uble sugars and sugar-acid ratio,were markedly higher in amino-acid fertilizer treatments relative to CK and T1,with T2 presenting the highest values of these quality parameters.Regarding nitrogen uptake and utilization,dry matter accumulation and nitrogen uptake of treatments with supplementary liquid amino-acid fertilizers were significantly higher than those of CK and T1.Nitrogen use efficiency of these treatments was 8.71-10.69 percent-age points higher than that of T1,and T2 obtained the optimal nitrogen utilization performance.In conclusion,the application of liquid amino-acid fertilizers can significantly improve tomato yield,fruit quality and nitrogen use efficiency,among which treatment T2 shows the optimal comprehensive performance.关键词
