肉蛋白生物有机肥对胡麻干物质积累、产量及品质的影响

Effect of meat protein biological organic fertilizer on dry matter accumulation,seed yield and quality of oilseed flax

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 fertilizer as control,we studied the effect of dry matter accumulation,seed yield and quality of oilseed flax（ Linum usitatissimum L.） by single application of chemical fertilizer,single application of meat protein biological organic fertilizer and different proportion of meat protein biological organic fertilizer and chemical fertilizer combined application in the field. The results are as follows：（ 1） Meat protein bio organic fertilizer increased plant height,stem diameter and promote the dry matter accumulation process of flax. After the bud period,the dry matter accumulation rate significantly increased under 30% meat protein biological organic fertilizer instead of chemical fertilizer（ T4）,being 102. 33%,55. 16%,58. 68%（ P〈0. 05） as compared to no fertilization CK（ T1） at flowering stage,fruiting stage and mature stage,respectively.（ 2） The actual production per unit area under 30% meat protein biological organic fertilizer instead of chemical fertilizer（ T4） increased by 73. 66%,17. 49%,13. 74%（ P〈 0. 01） than no fertilization CK（ T1）,single application of chemical fertilizer（ T2） and single application of meat protein bio-organic fertilizer（ T3）,respectively.（ 3） The different proportion of meat protein bio organic manure and chemical fertilizer improved the quality of flax,the oilseed flax has the best oil content under 30% meat protein biological organic fertilizer instead of chemical fertilizer（ T4）,The content of linoleic acid and linoleic acid is higher under 60% meat protein biological organic fertilizer instead of chemical fertilizer（ T5）. In conclusion,30% meat protein biological organic fertilizer instead of chemical fertilizer should be the best treatment.
