小麦穗大粒饱主要决定于中后期的田间管理。1979年我省伏旱加秋旱,冬早加冬冷,麦苗生长受到重大影响,二、三类苗较多。冬春虽然加强了管理,但群体已经受到了影响,亩穗数可能要少于1978和1979年。前期丢了后期补,穗数丢了用粒数和粒重来补。加强拔节以后的田间管理,对增加粒数和提 Large grain of wheat spike depends mainly on the field management in the late. In1979, the drought-relieving drought in our province was added in autumn, the winter was added in early winter, and the growth of wheat seedlings was greatly affected. Although winter and spring have strengthened management, but the group has been affected, the number of acres per spike may be less than in 1978 and 1979.
