水氮耦合对春茬设施黄瓜光合特征以及产量和品质的影响
Effects of Water and Nitrogen Coupling on Photosynthetic Characteristics,Yield and Quality of Spring Cucumber in Greenhouse
摘要
Abstract
Studying the effects of different water and nitrogen coupling treatments on the photosynthetic char-acteristics,yield and quality of spring cucumber can provide a theoretical basis for scientific water and ni-trogen management of cucumber in North China.Using spring cucumber in greenhouse as the test material,a secondary saturation D-optimal design scheme was adopted,with irrigation limits set at four levels of field ca-pacity(FC)of 78.00%,87.55%,93.35%,and 100%,and nitrogen application rates set at four levels of 0,434.21,697.43,and 999.90 kg/hm2.Cross experiments were conducted between T1-T8 treatments to deter-mine the effects of different water and nitrogen coupling treatments on cucumber photosynthetic characteristic parameters,yield,and quality.The results showed that the T7 treatment(irrigation upper limit level of 100%FC,nitrogen application of 999.9 kg/hm2)had the best comprehensive performance in photosynthetic character-istics.The T6 treatment(irrigation upper limit level of 93%FC,nitrogen application of 0 kg/hm2)had the highest single plant yield and water use efficien-cy.The T2 treatment(irrigation upper limit level of 78%FC,nitrogen application of 434.21 kg/hm2)had the highest nitrogen partial productivity,with a the-oretical maximum value of 14.21 kg/kg.The fuzzy Borda method was used to comprehensively evaluate the evaluation values and rankings of primary indica-tors of cucumber under different water nitrogen coupling treatments.The results showed that T6 treatment had the highest comprehensive score and was the optimal treatment in this experiment.On the basis of T6 treatment,combined with the application of base fertilizer,moderately reducing the amount of topdressing nitrogen fertilizer and irrigation water can achieve a balance between cucumber quality,yield,and water and fertilizer utilization efficiency during the production process.关键词
