摘　　要：本文以加工型马铃薯大西洋为试验材料,系统研究了羊厩肥与氮磷化肥配施对马铃薯干物质积累及产量的影响。结果表明,羊厩肥、NP化肥及两者配合施用均提高了马铃薯全株的干物质积累量,地上茎叶和地下块茎干物质积累量均表现为羊厩肥+NP肥>NP肥>羊厩肥>CK;叶片、地上茎、块茎的干物质日增长速率最大值出现时间均随羊厩肥+NP肥、NP肥、羊厩肥的施用而延后。在无肥和NP肥基础上施用羊厩肥、在无肥和羊厩肥的基础上施用NP肥,均可提高马铃薯各时期植株干物质含量,且具有显著的正累积效应。地上茎干物率和块茎增长期以后的叶片干物率均为施肥处理大于CK,而块茎干物率则为CK大于施肥处理。羊厩肥与NP肥配合施用,对马铃薯具有明显的增产效果。In this paper, we conduct a research on the processing type potato of DaXiyang, systematically study the effect of the stable manure, NP fertilizer and their interaction on the accumulation of the dry matter and yield of the potato. It is concluded that the application of stable manure or NP fertilizer or both of them all can increase the dry matter accumulation of the whole plant , dry matter accumulation of leaves, stems and tubers manifested as stable manure ＋ NP fertilizer 〉 NP fertilizer 〉 stable manure 〉 CK. The peak time of dry matter accumulation of leaves, stem and tubers is different, exerts postponed a few days. The application of stable manure, NP fertilizer or both of them can prolong the time when the maximum of daily increase rate come forth. It is a fact that application of manure without any fertilizer or in accord with NP fertilizer can enhance the dry matter, the same as the application of NP fertilizer without any fertilizer or in accord with manure, they all exerts a obvious stimulation, effect. The dry matter content of stem and that of leaves after the inflated period of tuber all increased if we make application of fertilizer treatment, which is greater than the application of CK. However, the dry matter content of tubers exerts a opposite direction, that is to say that the function of CK is greater than fertilizer treatment. The application of stable manure and NP fertilizer interaction can evidently increase the output of potato.
