以不施肥为对照,通过田间试验,研究了单施化肥、单施肉蛋白生物有机肥和不同比例肉蛋白生物有机肥与化肥配施对胡麻干物质积累分配规律、产量及品质的影响。结果表明:肉蛋白生物有机肥增加了株高和茎粗,促进了胡麻干物质积累进程,现蕾期以后30%肉蛋白生物有机肥替代化肥(T4)处理的干物质积累速率明显增加,盛花期、子实期、成熟期分别比不施肥CK(T1)增加102.33%、55.16%、58.68%(P<0.05);肉蛋白生物有机肥提高了胡麻产量,单位面积实际产量T4处理比不施肥CK(T1)、单施化肥(T2)和单施肉蛋白生物有机肥(T3)处理分别增加了73.66%、17.49%、13.74%(P<0.01);不同比例肉蛋白生物有机肥与化肥配施改善了胡麻品质,T4处理下胡麻含油率最佳,60%肉蛋白生物有机肥替代化肥(T5)的处理胡麻籽粒亚麻酸及亚油酸含量较高。综合考虑,30%肉蛋白生物有机肥替代化肥的效果最佳。
With no fertilization as control, the effects of single chemical fertilizer, single meat protein bio-organic fertilizer and different proportions of meat-protein bio-organic fertilizer and chemical fertilizer on dry matter accumulation and distribution, yield and quality of flax were studied through field experiments. The results showed that meat protein bio-organic fertilizer increased the plant height and stem diameter, promoted the process of dry matter accumulation of flax, the dry matter accumulation rate of 30% meat protein bio-organic fertilizer instead of chemical fertilizer (T4) Compared with non-fertilizing CK (T1), flowering, fruiting and maturity increased by 102.33%, 55.16% and 58.68%, respectively (P <0.05); meat protein bio-organic fertilizer increased flax yield and the actual yield per unit area The treatments of CK (T1), single fertilizer (T2) and single meat protein bioorganic fertilizer (T3) increased by 73.66%, 17.49% and 13.74% respectively (P <0.01) Application improved flax quality, T4 treatment under the best oil content of flax, 60% meat protein bio-organic fertilizer instead of fertilizer (T5) treatment flax seed linolenic acid and linoleic acid content is higher. Taken together, 30% meat protein bio-organic fertilizer to replace the best effect of fertilizers.
