阿里地区地处高原,该地区平均海拔在4500米,被称为“世界屋脊的屋脊”。由于受气候、海拔及地势结构的影响,当地的大部分农区目前没有种植春小麦,种植油菜品种单一,为了打破这种局面,选育出更适应在阿里种植的春小麦及油菜品种,2011年从拉萨农科所引进春小麦和油菜共7个优质品种,在阿里地区普兰县西德村和科加村进行试验试种,通过对各良种的产量性状和生育期指标的调查,科学评价了各新品种在本地的进一步再试种价值,以期为阿里地区良种选育工作提出合理化建议。
Ali area is located in the plateau, the average elevation of 4500 meters in the region, known as “roof of the roof ”. Due to the influence of climate, altitude and topography, most of the local agricultural areas do not plant spring wheat at present and cultivate a single species of rapeseed. In order to break this situation, the spring wheat and rapeseed species more suitable for planting in Ali were bred. In 2011, Seven high quality varieties of spring wheat and rapeseed were introduced into Lhasa Nongke. Experimental planting was carried out in Xi’de Village and Kejia Village, Pulan County, Ali Prefecture. According to the investigation of yield traits and growth period indexes of various elite species, Varieties in the local further re-test kinds of value, in order to Ali region breeding proposals put forward rationalization proposals.
