【摘要】 结合阿坝州实际 ,试用灰色系统理论中关联度分析法 ,对 14个早熟冬小麦和春小麦品种的单位面积产量、株高等 10个性状进行分析。分析结果表明 :在品种选择上 ,两类小麦品种都需要具有千粒重高、分蘖力强的特性 ,春小麦侧重于穗子较长、冬小麦侧重于有效穗较高 ;在栽培管理上 ,两类小麦都需要创造必要的基本苗数 ,春小麦要早施追肥、促根增蘖 ,冬小麦要适施追肥、巧施孕穗肥 ,保证群体产量提高。更多还原

【Abstract】 Joining the reality of Aba district, the 10 main agronomic characters of 14 winter-wheat and spring-wheat variety were analyzed by using the way of grey correlation degree. The results showed that on selecting variety two sorts of variety need higher 1000-grain weight and stronger branch ability, spring-wheat need longer spike length, winter-wheat need higher effective branch. On cultivating, they all need creating necessary essential seeding number, spring-wheat need early using seeding-fertilizer and conceiving-fertilizer properly, insuring the total yield.更多还原
