Abstract

Abstract:

A pot experiment was conducted with five nitrogen fertilizer treatments（N0：no nitrogen application；N1：ordinary urea；N2：loss-control urea；N3：stable urea；N4：humic acid urea）and two calcium fertilizer levels（Ca0：no calcium；Ca1：applied calcium），resulting in a total of 10 treatments，to investigate the mechanisms by which novel urea combined with calcium fertilizer affects photosynthetic characteristics，yield，and quality of‘Mayman’non-heading Chinese cabbage. The results showed that under the condition without applying calcium fertilizer，the Ca0N3 and Ca0N4 treatments significantly increased the nitrogen and calcium accumulation，nitrogen fertilizer utilization rate and agronomic efficiency of non-heading Chinese cabbage compared with the Ca0N1 treatment. When urea-calcium fertilizer was applied in combination，the Ca1N4 treatment significantly enhanced the activities of NR and GS enzymes，photosynthetic gas exchange parameters（P_n，T_r，G_s），Rubisco enzyme activity and chlorophyll fluorescence parameters（F_v/F₀，F_v/F_m，Φ_PSII，NPQ，Φ_CO₂and ETR）compared with the Ca1N1 treatment. Without calcium application，the yields of non-heading Chinese cabbage under Ca0N3 and Ca0N4 treatments increased by 22.48% and 23.64%，respectively，and the soluble sugar content significantly increased by 23.99% and 25.01% compared with ordinary urea；the soluble protein content under the Ca0N4 treatment increased by 13.73%. Under the combined application with calcium fertilizer，Ca1N3 and Ca1N4 treatments increased the yield by 34.33% and 35.24%，respectively，significantly reduced the nitrate content，and significantly increased the vitamin C content by 7.12% and 10.47% compared with ordinary urea. In comprehensive comparison，the combined application of humic acid urea and calcium fertilizer achieved the best effect.

Key words: non-heading Chinese cabbage, loss-control urea, stable urea, humic acid urea, photosynthetic characteristics, yield, quality
