摘　　要：为了提高“三沼”综合利用,探讨施用沼肥对马铃薯增产效果及抗病性的影响,该试验共设4个处理,以不施沼肥为对照。结果表明,处理2~4较处理1对照增产效果明显。以处理4各项经济性状指标最高,株高为78 cm,单株结薯数6.4个,单株薯重1.1 kg,平均薯重0.172 kg,大中薯率达86.2%,折合亩产达到1549.8 kg。处理2~4与处理1对照产量差异达到极显著水平,处理3,4与处理2之间差异极显著。同时沼肥对防治马铃薯黑痣病和晚疫病有一定作用。In order to improve the comprehensive utilization of biogas fermentation products,the effect of biogas fertilizer on potato yield and disease resistance were studied.A total of 4 treatments were set.The results showed that,comparing with treatment 1(control),treatment 2,3,4 had obvious effect on increasing yield.Treatment 4(3 times root irrigation+2 times spraying with biogas fertilizer)was the best,plant height was 78 cm,the average tuber number per plant was 6.4,the average tuber weight per plant was 1.1 kg,and the average weight per tuber was 0.172 kg.The proportion of large and medium potato reached 86.2%,and the equivalent yield reached 1549.8 kg per mu.The yield differences between treatment 2,3,4 and treatment 1 were extremely significant,and the differences between treatments 3,4 and treatment 2 were significant.At the same time,biogas fertilizer had certain effect on controlling potato nevus and late blight.
