有机肥对胡麻产量和品质的影响

Effect of Different Organic Manures on Yield and Quality of Oil Flax

以不施肥(T1)和施用化肥(T2)为对照,比较了农家肥(T3)、胡麻油渣(T4)、肉蛋白生物有机肥(T5)、绿能瑞奇精制有机肥(T6)、金阜丰土壤调理剂(T7)、优质豆粕生物有机肥(T8)、黑珍珠生物有机肥(T9)、爸爱我生物有机肥(T10)、HA有机肥(T11)和益撒803生物有机菌肥(T12)等不同有机肥对胡麻产量和品质的影响。结果表明,化肥可明显加快胡麻前期的生长速度;有机肥促进胡麻植株中后期的生长发育,现蕾期以后干物质日积累量明显增加,盛花-青果期达到高峰值,日积累量达333.51 mg·株-1·d-1,比T1显著增加20.80%。施用有机肥处理的产量均显著高于T1处理,T4、T8比T2处理分别显著增产9.92%、10.38%。胡麻产量与有效分茎数和单株有效果数呈极显著正相关,相关系数为0.84和0.82。施用有机肥处理的胡麻籽粒粗脂肪含量显著高于T1处理,T8处理的亚麻酸含量比T2处理的显著增加了3.78%。

The field experiment studiedinfluences of 10 different organic manures application on oil flax yield and quality. The 10 organic manures included farmyard manure（T3）, oil flax residue（T4）,‘Roudanbai’ bio-fertilizer（T5）, ‘Lvnengruiqi’ refined organic fertilizer（T6）, ‘Jinfufeng’soil conditioner（T7）, high quality soybean meal biological organic fertilizer（T8）,‘Heizhenzhu’（T9） and‘Baaiwo’bio-fertilizers.Treatments without fertilizer（T1） and with chemical fertilizer（T2） were used as controls.The results showed chemical manures can obxiously increase the growth rate of oil flax at early stage. The organic manures can promote growth and development of oil flax at middle-late stage; they significantly increase dry matter acculmination per day after the squaring period, which reached peak value which were 333.51 mg·plant-1·d-1 between full flowering and young fruit stage and increased by 20.80% and 9.75% over controls. The yield under different organic fertilizer appilications were significantly increased over treatment without fertilizer. T4 and T8 yields increased by 9.92% and 10.38% over treatment with chemical fertilizer respectively. The flax yield had a extremely notable relationship with both pod number stem and pod number per plant, with correlation coefficient of 0.84, 0.82 respectively. The content of grain crude fat under different organic fertilizer appilications were significantly higher than the treatment without fertilizer, and the content of linolenic acid of T8 significantly increased by 3.78% over treatment with chemical fertilizer.
