Abstract:

The study aims to explore the effect of combined application of microbial fertilizer and chemical fertilizer on the yield and quality of mini Chinese cabbage, and to explore the appropriate dosage ratio, so as to provide scientific fertilization basis for the production of mini cabbage in Beijing. ‘Jingchunwa No.4’ mini cabbage was used as the experimental object. T1-T4 different amounts of microbial fertilizer [T1: compound microbial fertilizer (12-0-3) 300 kg/hm2+ compound fertilizer (18-9-18) 315 kg/hm2, T2: compound microbial fertilizer (12-0-3) 300 kg/hm2+ compound fertilizer (18-9-18) 157.5 kg/hm2, T3: compound microbial fertilizer (12-0-3) 150 kg/hm2+ compound fertilizer (18-9-18) 315 kg/hm2 and T4: compound microbial fertilizer (12-0-3) 150 kg/hm2+ compound fertilizer (18-9-18) 157.5 kg/hm2] combined with chemical fertilizer as base fertilizer and conventional fertilization [CK, bio-organic fertilizer 600 kg/hm2+ compound fertilizer (15-15-15) 375 kg/hm2], a total of 5 treatments were compared. The results showed that the appropriate combination of compound microbial fertilizer and chemical fertilizer could increase the yield and soluble protein content of mini cabbage to a certain extent. Compared with conventional fertilization, the biological yield and economic yield of T1 treatment were significantly increased by 20.50% and 16.63%, respectively, and the soluble protein content was significantly increased by 45.59%. The nutrient accumulation of mini cabbage in the whole growth period was as followed: mature stage> heading stage> rosette stage> seedling stage. It needed 1.39 kg N, 0.85 kg P2O5 and 0.62 kg K2O to produce 1000 kg mini cabbage. Therefore, compound microbial fertilizer (12-0-3) 300 kg/hm2+ compound fertilizer (18-9-18) 315 kg/hm2 could be used as one of the recommended fertilization measures in the production of mini Chinese cabbage.
