以常规施用化肥为对照，开展等价生物有机肥与化肥对马铃薯性状和产量的影响试验。结果表明：随着用量的增加，等价生物有机肥较化肥马铃薯产量依次提高4.9%、1.9%、4.3%，增产幅度较小，产量差异不明显。但对马铃薯的农艺性状影响明显，马铃薯现蕾期后生长速度加快，叶片宽、厚，茎杆粗壮，叶色深且有光泽；块茎整齐，表皮光亮；早晚疫病叶数减少9.7%；终花期延长5~10 d。综合比较分析，投入生物有机肥9450元/hm2(即生物有机肥用量3000 kg/hm2)，产量高达54170.4 kg/hm2。%With conventional fertilizers as control,we conducted effect of equivalent bio-organic fertilizer and fertilizer on the agronomic traits and yield of potato.The results showed that with the increasing of the application amount compared with chemical fertilizers the yield of the equivalent investment in bio-organic fertilizer treatments increased 4.9%,1.9%,4.3%increased,slightly and didn’t not reach a significant level.But the impact on the agronomic traits of potato reached a significant level,after squaring,potato growed faster,leaves changed width,thick,dark and shiny;Tubers were nest and bright;Epidemic disease of the leaf reduced by 9.7%;final flowering delayed 5~10 days.Comprehensive analysis,bio-organic fertilizer input 9 450 yuan/hm2(bio-organic fertilizer 3 000 kg/hm2),the yield increased to 54 170.4 kg/hm2.
