摘　　要：以青薯9号为供试品种,分为5个处理组开展马铃薯有机肥替代化肥试验。结果表明:有机肥完全代替化肥不能满足马铃薯关键生育期对养分的需求,建议用有机肥替代部分化肥,使有机肥和化肥配合施用,从而提高马铃薯的商品率和产量。Qingshu 9 was used as the test variety,the experiment of organic fertilizer instead of chemical fertilizer was carried out in five treatment groups.The results showed that completely replacing chemical fertilizer with organic fertilizer could not meet the nutrient demand of potato in the key growth period.It was suggested that organic fertilizer should be used to replace part of chemical fertilizer,so that organic fertilizer and chemical fertilizer can be used together,so as to improve the commodity rate and yield of potato.
