摘 要 ：通过田间试验，以不施肥为对照（CK），研究了单施化肥(T₀)、不同比例氨基酸配方有机肥与化肥配施和单施氨基酸配方有机肥（T₁₀₀）对胡麻干物质积累分配规律、产量、品质及氮肥利用效率的影响。结果表明：（1）氨基酸配方有机肥对胡麻出苗率具有明显促进作用，且随着氨基酸配方有机肥施用量的增加胡麻出苗率提高。（2）氨基酸配方有机肥促进了胡麻干物质积累进程，增加了干物质积累总量，如在成熟期时，30%氨基酸配方有机肥与70%化肥配施(T₃₀)处理的干物质积累总量最大，比不施肥、单施化肥和单施有机肥处理分别显著增加60.52%、37.01%和29.97%；且T₃₀处理的产量与不施肥（CK）、单施化肥(T₀)、单施生物有机肥（T₁₀₀）相比分别增加了72.07%、16.47%、13.30%。（3）不同比例氨基酸配方有机肥与化肥配施的处理下均可改善胡麻的品质，提高胡麻氮肥利用效率，其中在30%氨基酸配方有机肥替代化肥(T₃₀)的情况下胡麻干物质积累、产量及亚麻酸含量最高，60%氨基酸配方有机肥替代化肥(T₆₀)的情况下胡麻亚油酸含量较高。研究认为，30%氨基酸配方有机肥与70%化肥配施对当地胡麻生产的影响效果最佳。

Abstract:To study the effect of amino acid organic fertilizer and chemical fertilizer application for day matter accumulation, seed yield and quality of oil flax, without fertilizer as contrast under field conditions，we analyzed the single application of fertilizer, the proportion of different formula of amino acid organic manure and chemical fertilizers application and single application of amino acid organic fertilizer formula for flax. The results showed: (1) amino acid organic fertilizer had obvious effect for germination rate, and with the amino acid organic fertilizer increased the germination rate increased. (2) Amino acid organic fertilizer promoted the dry matter accumulation process and increased the total amount of dry matter accumulation of flax. In mature stage,30% organic fertilizer + 70% chemical fertilizer compared with no fertilizer, 100% chemical fertilizer and 100% organic fertilizer the total dry matter were significantly increased by 60.52%, 37.01% and 29.97%, respectively. Considering 30% organic fertilizer + 70% chemical fertilizer is the best effect, compared with no fertilization, 100% chemical fertilizer and 100% organic fertilizer, the yield increased by 72.07%, 16.47%, 13.30%, respectively. (3) In the case of 30% organic fertilizer + 70% chemical fertilizer alternative fertilizer, flax dry matter, seed yield and linolenic acid content is the highest, and 60% organic fertilizer + 40% chemical fertilizer alternative fertilizer, flax linoleic acid content is the highest.Considering the 30% organic fertilizer + 70% chemical fertilizer effect on local flax production of the best.
