摘　　要：对泛麦8号小麦2004-2012年9 a的主要性状与主要气象因子相关性进行分析.结果表明:单产与株高呈显著负相关,与冬前均温、越冬均温、后期均温、冬前降水量、春季降水量呈负相关,与成熟期、最高蘖、有效穗、穗粒数、千粒重呈正相关;小麦成熟期与各时段均温、冬前降水量、越冬降水量、春季降水量、春季日照、后期日照呈负相关,与后期降水量、冬前日照、越冬日照呈正相关.在小麦高产栽培中,培育冬前壮苗,走"小壮高"道路,可以在不增加株高的前提下,增加群体、增粒增重,达到高产稳产的目的;温度升高、降水集中,特别是冬前和冬季集中降水可降低小麦产量,日照时数增加,小麦产量提高.By correlation analysis of main characters of Fanmai 8 wheat with meteorological factors in year 2004 to 2012, the results indicated that yield significantly negative correlation to plant height,negative to average temperature before winter, in winter and later stage,rainfall before winter and spring,positive to mature date,highest density, available spikes,kernels per ear,1000-kernel weight.Wheat mature date negative to average temperature in every stage,rainfall before winter and spring,sunshine of spring and later.Positive to rainfall of later stage,sunshine before winter and in winter.In order to obtain high yield,the strong seedling and ＇small density,strong plant and high yield＇ technology is available.By the same time,plant height is limited,density and kernels weight increased.When temperature increasing,rainfall concentrating,especially in winter,wheat yield will reduce,and during long-days, wheat yield will increase.
