Abstract
Comparing the yield with yield structure of winter wheat under fertilization or no,it showed that spikes per hectare,grains per spike and kilo-grain weight increased extremely remarkably under fertilization,which affected together and made for the yield increasing.Under fertilization,the biomass increased extremely remarkably,however harvest index was affected unremarkably.The different varieties had different harvest index,and the harvest index had extremely remarkably contrary correlation with plant height.
