微生物菌剂对快生菜品质和产量的影响

目的]研究微生物菌剂对快生菜穴盘种植产量和品质的影响。方法]快生菜品种为小白菜(Brassica rapa L.chinensis Group.),共设2个处理,处理1为常规管理+微生物菌剂200倍稀释进行灌根,处理2为常规管理+与处理1同期等量清水灌根,即对照。结果]施用微生物菌剂的快生菜平均增产量27 685.35 kg/hm2,带来的纯利润为42 770.7元/hm2,产投比为3.39∶1;可提高可溶性糖、叶绿素和VC含量,降低硝酸盐含量17.29%,显著改善快生菜品质。结论]该研究可为设施栽培环境下微生物菌剂的大面积推广应用提供科学依据。

Effects of Microbial Agents on Quality and Yield of Fast-maturing Vegetables

Objective] The objective of this study was to study the effects of microbial agents on quality and yield of fast-maturing vegetables.Method]The Fast-maturing vegetable was Brassica rapa L.chinensis Group..Two treatments was designed,thereinto,treatment 1 was normal management ＋ root-irrigation with microbial agents of 200-fold dilution,treatment 2 was normal management ＋ root-irrigation with the same amount of water as treatment 1 at the same time,namely control.Result]The results showed that using microbial agents increased the fast-maturing vegetables yield by an average of 27 685.35 kg / hm2,brought profits of about 42 770.7 CNY/hm2,and the value to cost ratio（VCR） was 3.39∶ 1;it could also raise the content of soluble sugar,chlorophyll and VC,and reduce the nitrates content by 17.29%,prominently improve the quality of fast-maturing vegetables.Conclusion]The study provides a scientific basis for microbial agents’promotion and utilization in a large scale under protected cultivation.
