青稞(Hordeum vulgare L.var.nudum Hooker f.)即裸大麦,为我国青康藏高原地区的主要粮食作物。近年来经驗証明,青稞不是低产作物而是高产作物。青稞成熟早,生长期短,特别适宜于海拔高、无霜期短的高原地区栽培,近年来其栽培高度已推移到拔海4,500米的地区(西藏帕里)。由于青稞生长期短,成熟早,它的生长和生理特点也 Barley (Hordeum vulgare L.var.nudum Hooker f.) That is, naked barley, as the main food crops in the Qinghai-Tibet Plateau. In recent years, experience has shown that barley is not a low yield crop but a high yield crop. Barley mature early, short growth period, especially suitable for high altitude, frost-free short plateau cultivation, in recent years its cultivation altitude has shifted to pull the sea 4,500 meters (Parry, Tibet). As the barley growth period is short, mature early, its growth and physiological characteristics also
