摘要
利用山东省和陕西省中部45个气象台站建站至1990年的气象资料,采用欧氏距离的计算方法,并按照各气候要素不同的权重系数进行修正,求出综合相似距。结果表明:1)山东省大部分地区可以直接从陕西中部地区引种冬小麦推广品种;2)山东省主要种植冬性和半冬性品种,大部分地区可在暖冬年引种超大穗小麦,以发挥其高产优势。
By use of 45 stations data in Shandong Province and in the centre of Shaanxi Province and the Euclidean distance method,the agroclimatic analogue diagnosis of introduced variety of winter wheat was conducted,the results showed:a)the super ear wheat varieties can be introduced directly from the central section in Shaanxi Province in the most of Shandong Province;b) because of planting wintriness and semi wintriness wheat varieties in Shandong,the super ear wheat variety from Xianyang may be planted in warm winter years,to avoide freezing injury and give the high yield superiority.
