1 Materials and methods Test site: Soil and Fertilizer Laboratory, Rice Research Institute, Heilongjiang Academy of Reclamation Sciences, 2002 Experimental field; Rice varieties tested: Kong Yu 131. 2003 Experimental Plantation of Plant Protection Research Institute, Rice Research Institute of Heilongjiang Academy of Reclamation Sciences; Rice cultivars: Kennamen Rice number 6. 2002 trial treatment: set up two treatments and one routine control. Treatment 1: Sanlong biological grain fertilizer 45.0kg / hm ~ 2 as a base fertilizer, coupled with conventional nitrogen fertilizer top dressing to reduce the total amount of 45.0kg / hm ~ 2. Treatment 2: Sanlong bio-granule fertilizer 45.0kg / hm ~ 2 as a base fertilizer, coupled with top dressing nitrogen fertilizer conventional total reduced 90.0kg / hm ~ 2. Treatment 3: Control for Honda conventional fertilizer. Conventional fertilizers are: urea 200.0kg / hm ~ 2, diammonium phosphate 100.0kg / hm ~ 2, potassium sulfate 80.0kg / hm ~ 2. Urea application rate of each growth stage based on: tiller: transfer: ear: grain = 3: 3: 1: 2: 1, all of DAP as basal fertilizer, sulfur
