摘　　要：为减少化肥的使用量,在油菜生产上寻求有机肥替代化肥的可行性,湟中县农业技术推广中心在上新庄镇尧湾村进行了有机肥不同用量替代化肥试验。结果表明:油菜田有机肥替代常规施肥从30%-100%的不同处理产量呈上升趋势,全部施用有机肥的小区产量达到最高306.67kg,比常规施肥区的214.11kg,增产92.56kg、增幅43%,同时全部施用有机肥的小区表现出植株健壮,叶色深绿,长势良好,有一定的优越性,但是油菜生长会出现贪青现象,影响千粒重,使千粒重比常规施肥低0.11g、比无肥区低0.07g,生育期延迟9d。In order to reduce the amount of chemical fertilizer used and to find the feasibility of replacing chemical fertilizer with organic fertilizer in rape production,Huangzhong County Agricultural Technology Extension Center conducted an experiment on replacing chemical fertilizer with different amounts of organic fertilizer in Yaotan Village,Upper xin zhuang zhen.The results showed that the yield of rape field with organic fertilizer instead of conventional fertilization increased from 30%to 100%.The yield of the plot with all organic fertilizers reached the highest 306.67 kg,which was 92.56 kg higher than that of the plot with conventional fertilization and 43%higher.At the same time,the plot with all organic fertilizers showed strong plants,dark green leaves,good growth and certain advantages.However,the rape growth showed green-greedy phenomenon,which affected the 1000-grain weight,making the 1000-grain weight 0.11 g lower than that of the plot with conventional fertilization,0.07 g lower than that of the plot without organic fertilizer,and delaying the growth period by 9 days.
