摘　　要：通过田间试验,对不同氮肥水平对亚麻主要性状和产量的影响进行分析。结果表明,氮肥的施用量与株高、工艺长度、茎粗和单株茎重呈显著正相关,增施氮肥可以有效促进亚麻株高、工艺长度、茎粗和单株茎重的生长发育,从而提高亚麻原茎产量。在新疆亚麻主产区每666.7m2施用N 3kg可以保证较高的原茎产量和最高的纤维含量。Through field experiment , the major agronomic characters and stalk yield of flax which were affected by different nitrogen fertilizer inputs were studied in this paper.The results showed that there was a significant positive correlation between the nitrogen fertilizer input dosages and parts of flax agronomic characters , such as plant height , bundle length , stem diameter and single plant weight.To in-crease the nitrogen fertilizer input could improve the flax plant height , bundle lengths , stem diameter and single plant weight , so as to increase flax stalk yield in the end.In Xinjiang, 3 kg nitrogen fertilizer in-put per 666.7 m2 could keep flax have a relative stead stalk yield and the best fiber content.
