Effects of Row Spacing on Carbon and Nitrogen Transportation，Grain Nitrogen Input in Winter Wheat

doi:10.7668/hbnxb.2011.01.037

Abstract

Abstract: Field plot experiments were carried out to examine the effects of row spacing on carbon and nitrogentransportation，nitrogen input to grain in winter wheat with two spike types on the farm of Henan Agricultural Universi-ty during 2006－ 2007. The results showed that the assimilation accumulation after anthesis and contribution of assimi-lation accumulation to grain weight firstly increased and then decreased with reaching peak value.

Key words: Winter wheat, Row spacing, Assimilation translocation, Nitrogen input
