摘　　要：合理施用微生物菌剂可显著改善蔬菜土壤环境,增加产量,提升品质。本试验以不结球白菜为供试材料,在设施条件下设置不施微生物菌、施用液态和固态微生物菌剂处理,研究不同形态微生物菌剂对不结球白菜生长和品质的影响。结果表明:施用液态和固态微生物菌剂均能显著提高土壤脲酶活性,增加植株全氮含量,增大叶面积,显著提升叶片SPAD值,提高叶片净光合速率,产量比不施微生物菌剂处理分别增加26.9%和34.4%。同时,施用微生物菌剂可提高不结球白菜的总酚和抗坏血酸含量,显著降低硝酸盐含量。可见,合理施用微生物菌剂可促进不结球白菜产量的提升和品质的改善。不同形态微生物菌剂中,液态微生物菌剂时效快,固态微生物菌剂长效性好,可根据土壤肥力情况酌情配施有机肥或无机肥以促进蔬菜的优质高产。Reasonable application of microbial agents can significantly improve soil environment and increase the yield and quality of vegetables. In this study, we examined the effects of different forms of microbial agents on the growth and quality of Brassica rapa L. ssp. chinensis Makino(non-heading Chinese cabbage) under the conditions of no microbial agent application, liquid and solid microbe agents application. The results showed that compared with no microbial agent, application of liquid and solid microbial agent significantly improved soil urease activity, plant nitrogen content, leaf area, SPAD value, and net photosynthetic rate, and increased vegetable production by 26.9% and 34.4% respectively. Meanwhile, the total phenol content and ascorbic acid content of non-heading Chinese cabbage were increased and nitrate content was significantly decreased by applying microbial agents. Thus, rational application of microbial agents promoted the yield and quality of non-heading Chinese cabbage. From the perspective of vegetable growth, liquid microbial agents work fast, solid microbial agents had good long-term efficacy. The cooperating application with organic and inorganic fertilizers would facilitate the excellent quality and high yield of vegetables.
