Effect of Organic Fertilizer Substitution for Chemical Fertilizer on the Yield of Winter Wheat
In order to investigate the effect of organic fertilizer replacing chemical fertilizer on the yield of winter wheat,this paper used different proportions of bio-organic fertilizer and chemical fertilizer to fertilize winter wheat,and compared the growth period,main characters and yield of different treatments of wheat.The results showed that the combined application of bio-organic fertilizer and inorganic fertilizer had no significant effect on the whole growth period of winter wheat.With the increase of the application amount of bio-organic fertilizer,the wheat yield was first increased and then decreased,and the wheat yield of treatment 5(156 kg/hm2 organic fertilizer nitrogen and 39 kg/hm2 inorganic fertilizer nitrogen)was the highest.
