牛粪堆肥茶最优发酵条件研究

Study on Process Optimization for Brewing Compost Tea Made from Cow Manure

[目的]研究牛粪堆肥茶的最有发酵条件。[方法]以腐熟牛粪为发酵原料,研究不同发酵条件下制取的堆肥茶对白菜发芽率、根长、下胚轴长以及生物量的影响。[结果]结果表明,,堆肥茶发酵的最优条件为:肥水比1∶5,曝气量0.175 L/h,发酵时间2 d。[结论]该研究为堆肥茶的大规模应用提供技术参考。

[ Objective ] The purpose aimed to study the process optimization for brewing compost tea made from cow manure. [ Method] The effects of compost tea made from cow manure on germination rate, the length of root, the height and the biomass of the cabbage seed was studied. [ Result] The results showed that the optimum condition of brewing compost tea was ratio of compost and water 1：5, the aeration rate 0. 135 L/h, the brewing time 2 d. [ Conclusion] This research will provide technological references for cosmically applying compost tea.
