芥菜酵素液不同浓度与施用方式对大白菜生长和产质量的影响OA

[Objective]The effects of mustard fermentation solution with different concentrations and application patterns on growth,yield and quality of Chinese cabbage were investigated to provide a reference for utilization of the fermentation solution from waste vegetables.[Method]The agronomic traits,yield and quality of Qianbai 9,a Chinese cabbage variety,treated with mustard fermentation solution with 5 dilution concentrations ranging from 50 times,100 times,200 times,400 times and 800 times by using two application patterns of foliage spray(A)and root irrigation(B)on 0 d,15 d and 30 d after planting were determined at harvest stage.[Result]Compared to foliar spray pattern,the root irrigation pattern of mustard fermentation solution could promote growth,yield and quality of Chinese cabbage.The plant height,leaf length,leaf width and fresh weight of Chinese cabbage treated with mustard fermentation solution with×200 times by the root irrigation pattern reached 26.03 cm,31.10 cm,21.10 cm and 0.42 kg/plant separately and significantly higher than the negative control(CK),and its fresh weight increased by 223.08%compared with the negative CK.The leaf soluble protein and soluble sugar content of Chinese cabbage treated with mustard fermentation solution with×400 times by the root irrigation pattern reached 9.15 mg/g and 7.07 mg/g respectively.The root irrigation pattern could reduce soil pH.[Conclusion]The mustard fermentation solution has a significant regulation effect on growth of Chinese cabbage.The comprehensive effect of the root irrigation pattern is better than the foliage spray pattern.The root irrigation pattern of mustard fermentation solution with×100 times and×200 times has the better improvement effects on agronomic traits and yield of Chinese cabbage.The root irrigation pattern of mustard fermentation solution with×400 times is beneficial to improve quality of Chinese cabbage.The root irrigation pattern of mustard fermentation solution with×200 times or×400 times can be used to improve yield or quality of Chinese cabbage respectively.
