摘　　要：利用2017—2019年国家春小麦品种西北水地组区域试验和生产试验的数据资料,对银春10号产量及其构成因素分析。结果表明,在基本苗、最高茎蘖数、有效穗数、穗粒数和千粒重中,有效穗数、千粒重和穗粒数对银春10号的产量影响最大。实现银春10号高产稳产,要在适当控制基本苗的基础上,通过水肥管理等调控措施,以提高成穗率增加有效穗数为主,促大穗增加穗粒数,同时兼顾千粒重,以发挥银春10号的最大增产潜力。Based on the date of regional test and production test of spring wheat groundwork in northwest China from 2017 to 2019,analysis of the yield and its component factors of Yinchun No.10,The results showed that in the basic seedings,maximum tillers,effective panicle number,grains per panicle and 1000-grain weight,effective panicle number、1000-grain weight and grains per panicle had the greatest effect on the yield of Yinchun No.10.To achieve high and stable yield of Yinchun No.10,on the basis of proper control of the basic seedings,through water and fertilizer management and other regulatory measures,improve the productive tiller percentage and increase the effective panicle number,increase the numberar of grains per panicle by promoting lange panicle,and give consideration to the 1000-grain weight at the same time,to exert the maximum production potential of Yinchun No.10.
