摘要
[Objective] The paper aimed to explore influence of different factors on eggs hatching of Cryptotympana atrata,and optimize technical parameters in practice.[Method] By using hatching rate as index,L16(44)orthogonal design was employed to determine the effects of the four factors including temperature,salinity,photoperiod and pH.[Result] Photoperiod had obviously effects on hatchability of Cryptotympana atrata eggs.The optimal conditions for hatching were temperature 30 ℃,salinity 25%,photoperiod L12∶D12,and pH 6.[Conclusion]The research provided some scientific basis for indoor artificial incubation.
[目的]探索不同因素对蚱蝉卵室内孵化率的影响规律,优化卵孵化的技术参数。[方法]采用L16(45)正交重复试验设计,以卵孵化率为指标,考察温度、pH、光周期和盐度4因素对蚱蝉卵孵化的影响。[结果]光周期对蚱蝉卵孵化的影响达到了极其显著水平;4因素的搭配组合优方案为A3B3C3D2,即温度30℃、盐度25%、光周期L12∶D12和pH=6条件下蚱蝉孵化率表现较好。[结论]研究结果可作为蚱蝉卵室内人工孵化的科学依据。
