摘　　要：于2018年在黑龙江省农科院绥化分院试验区开展生物节氮增产技术对水稻生长发育和产量性状的影响试验,采用四种不同生物菌肥处理与常规施肥技术相比较,考查不同生物菌肥处理对水稻生长发育性状、产量构成因子和产量相关指标及节氮效果。结果表明,奕源生物菌剂处理节肥最多,比对照减氮肥18.6%,产量与对照相当。万丰达掺混肥处理产量最高,节肥量低于奕源生物菌剂处理,比对照减氮肥10.5%。以此明确不同生物菌肥的节氮效果,利用生物菌剂固氮补充水稻生长中后期所缺的氮养分,提高氮肥利用效率,达到作物减氮后防病安全增产的目的。Effects of biological nitrogen saving and yield increase technology on rice growth,development and yield characteristics were researched by Suihua Branch of Heilongjiang Academy of Agricultural Sciences in 2018.Four different biological bacterial fertilizer treatments were compared with conventional fertilizer treatments to investigate the effects of different biological bacterial fertilizer treatments on rice growth and development traits,yield components and yield-related indexes and the effect of nitrogen saving.The results showed that Yiyuan biobacterial agent had the most fertilizer saving and reduced nitrogen fertilizer by 18.6% compared with the control,and the yield was similar to the control.The yield of Wanfengda mixed fertilizer treatment was the highest,and the fertilizer saving amount was lower than Yiyuan biological agent treatment,and the nitrogen reduction was 10.5% compared with the control.In this way,the nitrogen saving effect of different biological bacterial fertilizers can be determined,and the nitrogen fixation of biological bacterial agents can be used to supplement the nitrogen nutrient deficiency in the middle and late stage of rice growth,so as to improve the nitrogen fertilizer utilization efficiency and achieve the purpose of disease prevention and yield increase after nitrogen reduction.
