不同类型肥料对当归产量和品质的影响
Effects of different types of fertilizers on yield and quality of Angelica sinensis
目的 探寻不同类型肥料对当归产量和品质的影响,为当归生态种植提供科学依据和参考。 方法 在化肥、生物菌肥和有机肥的基础上设置7个不同处理(T1磷酸二铵750 kg/hm2、T2 生物菌肥2 250 kg/hm2、T3生物菌肥2 250 kg/hm2+有机肥6 000 kg/hm2、T4有机肥12 000 kg/hm2、T5 有机肥18 000 kg/hm2、T6有机肥24 000 kg/hm2和T7有机肥30 000 kg/hm2),以不施肥为对照(CK),收获期测定当归产量和品质。 结果 不同类型肥料对提高当归产量及构成因素、主要活性物质含量以及体外抗氧化能力具有显著影响。其中,T3处理(生物菌肥+有机肥)效果最佳。T3相对于CK,根干质量、根长、侧根数和根直径分别增加172%、161%、138%和155%;以单株计算,阿魏酸、藁本内酯、可溶性糖、总黄酮、总酚类化合物含量以及总积累量分别增加224%、181%、146%、163%、181%和224%,DPPH抑制率和FRAP值分别增加165%和182%。相关性分析显示,活性物质总含量与DPPH抑制率和FRAP值均呈显著正相关,相关系数r分别达到0.711 5和0.748 8。 结论 生物菌肥2 250 kg/hm2+有机肥6 000 kg/hm2(T3)施用量可显著提高当归产量和品质,其效果要优于施用化肥、单一施用生物菌肥和过度施用有机肥。
Objective To find out the effect of different types of fertilizers on the yield and quality of Angelica sinensis,and to provide a scientific basis and important reference for ecological planting of A.sinensis. Method Seven different types of fertilizers (T1 diammonium phosphate 750 kg/hm2,T2 bacterial manure 2 250 kg/hm2,T3 bacterial manure 2 250 kg/hm2+organic fertilizer 6 000 kg/hm2,T4 organic fertilizer 12 000 kg/hm2,T5 organic fertilizer 18 000 kg/hm2,T6 organic fertilizer 24 000 kg/hm2 and T7 organic fertilizer 30 000 kg/hm2) were designed based on chemical fertilizer,bacterial manure and organic fertilizer without fertilization as the control (CK),and the yield and quality of A.sinensis were determined at the harvesting stage. Result There were significant effects of different types of fertilizers on yield and its components,contents of major bioactive compounds,and antioxidant capacity in vitro of A.sinensis.Among of the seven fertilizers,the T3 (bacterial manure+organic fertilizer) showed the best effects compared to CK,T1 (chemical fertilizer),T2 (bacterial manure),and T4,T5,T6,T7 (different amounts of organic fertilizer).Comparing T3 with CK,root dry weight (DW),root length,number of lateral roots,and root diameter increased by 172%,161% 138% and 155%,respectively.On a per plant basis,the content of ferulic acid,ligustilide,soluble sugars,total flavonoids,total phenolics,and total amount of major bioactive compounds increased by 224%,181%,146%,163%,181% and 224%,respectively.On a per plant basis,the percentage of DPPH and FRAP value increased by 165% and 182%,respectively.Correlation analysis showed that there was a significant positive relationship between the total amount of major bioactive compounds and the percentage of DPPH and FRAP value,with the r values of 0.711 5 and 0.748 8,respectively. Conclusion The T3 (bacterial manure 2 250 kg/hm2+organic fertilizer 6 000 kg/hm2) can significantly improve the yield and quality of A.sinensis.It is not conducive to improve the yield and quality by applying chemical fertilizer,biological bacterial fertilizer individually or organic fertilizer excessively.
