有机肥替代化肥对冬小麦产量的影响

Effect of Organic Fertilizer Substitution for Chemical Fertilizer on the Yield of Winter Wheat

为了探讨有机肥替代化肥对冬小麦产量的影响,采用生物有机肥和化肥搭配对冬小麦进行施肥处理,比较了不同处理小麦生育期、主要性状和产量。结果发现,生物有机肥和化肥一起配施对冬小麦的整个生育期的进程影响不显著,随生物有机肥施入量的增加,小麦产量呈先升高、后降低的趋势,以处理5(156 kg/hm^(2)有机肥氮+39 kg/hm^(2)氮肥)的小麦产量最高。

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/hm^(2) organic fertilizer nitrogen and 39 kg/hm^(2) inorganic fertilizer nitrogen)was the highest.
