[1]生物有机肥配合化肥施用对甜玉米的影响

To study the effects of chemical fertilizer substitution with biologicalorganicfertilizer on yield of Sweet corn,field test method was used,four treatments were set up,including CK(no fertilizer),treatment 1(100% chemical fertilizer), treatment 2 (50% biological organic fertilizer and 50% chemical fertilizer) and treatment 3(100%biological organic fertilizer). The results showed that the average yield of treatment 2 was 12944.4 kg / hm2,which was 12.6% higher than that of treatment 3 and 107.4% higher than that of CK; there was no significant difference in agronomic traits and yield components between treatment 2 and treatment 1,and the yield was similar. The best agronomic index and the highest yield was treatment2,it provides some reference for the development and utilization of agricultural wastes such as livestock manure and the application of biological organic fertilizer in production for the region.
