陕西关中东部小麦商品粮品质调查分析

Quality Investigation and Analysis of Wheat Commodity Grain in Eastern Guanzhong of Shaanxi

从陕西关中东部地区９个粮站的贮仓中抽取小麦商品粮样本１６个，测定其品质指标，并分析品质性状之间的相关性和小麦品质的地域差异及年际差异。结果认为：抽样地区北部低山丘陵区（海拔５５０～８００ｍ）小麦商品粮品质优于黄土台塬区（海拔４００～５５０ｍ）；该地区１９９５年入库小麦明显优于１９９６年入库小麦；小麦籽粒硬度、蛋白质含量和湿面筋含量能够较好地反映小麦商品粮的综合品质。

We took sixteen wheat samples from nine different warehouses in eastern Guanzhong of Shaanxi and their quality indices were measured.The relation of different quality characters,and quality differences among regions and years were analysed.We know:the quality of wheat commodity grain in hilly land (altitude 550-800 m) is better than that in table land (altitude 400-550 m) in eastern Guanzhong of Shaanxi.The grain harvested in 1995 was obviously better than that in 1996 in the same area.Kernel hardness,protein content and wet gluten content can greatly reflect the quality of wheat commodity grain.
