栽培方式对平凉山药农艺性状及产量的影响

Effect of Cultivating Methods on Agronomic Characteristics and Yield in Pingliang Yam

以平凉山药为试材,研究了3种不同栽培方式下山药的农艺性状和产量表现。结果表明,相对于常规平作栽培,套管和打洞栽培产量、成品产量、块茎全长和块茎单质量显著增加。块茎全长与龙头、横径与块茎单质量成显著正相关,块茎单质量与产量,成品产量成极显著正相关。打洞栽培是适于平凉山药的一种简单易行、节本增效的栽培方式。

Taking Pingliang yam as cultivating indicator, agronomic traits and yield performance of Pingliang yam under 3 cultivation methods had been studied. The results showed that, compared to the conventional cultivation, yield, marketable yarn, total length and single weight of yam tuber increased significantly when they were planted using plastic pipe and cultivating in burrow. While under 3 cultivation methods, there were no difference between yam leader and yam diameter. Correlation analyze results suggested that there were significantly positive relationships between total length of yam tubers amt yam leader, between yam diameter and single weight of tubers. And weight of single tubers was notable significantly positive correlated with yield and commercial products. Cultivating in burrow was a practicable and effective cultivating technique for Pingliang yam cultivation.
