不同栽培基质对马铃薯原原种产量性状和经济参数的影响

Effect of Different Substrates on Yield Traits and Economic Parameters of Potato Breeder's Seeds

[目的]筛选马铃薯原原种适宜的栽培基质。[方法]以马铃薯品种蓉紫芋5号脱毒试管苗为材料,采用单因素随机设计,设计6种基质类型,分析不同栽培基质对马铃薯原原种产量性状和经济参数的影响。[结果]以椰糠作为栽培基质可获得最高的产量和效益,其次是椰糠+营养土=1∶1的基质。[结论]以椰糠作为栽培基质用于马铃薯原原种生产最佳,具有较好的应用价值。

Objective] The aim was to screen out the optimal culture medium for potato breeder’s seed.[Method] With Rongziyu 5 virus-free tube shoot as material, using single factor randomized design, setting up six kinds of matrix, effects of different culture matrix on yield traits and economic parameters of potato breeder’s seeds were analyzed.[Result] The results showed that the maximum yield and economic benefit were obtained by the substrate formula of coconut chaff, followed by the substrate formula of coconut chaff ＋nutrition soil in the ratio of 1∶1.[Con-clusion] The substrate formula of coconut chaff for potato breeder’ s seeds production is best with good application value.
