摘要
目的:研究不同氮、磷、钾及有机肥施肥量对川芎产量的影响,为川芎规范化栽培技术的建立提供理论依据。方法:以彭山种植的川芎为材料,采用四因素五水平二次正交旋转组合设计,进行田间肥料试验,建立施肥与川芎产量函数模型。结果:通过模型解析,氮、磷、钾及有机肥对川芎产量有显著影响。肥料对川芎产量贡献率大小依次为钾肥>有机肥>氮肥>磷肥;氮肥和磷肥、氮肥和有机肥、钾肥和有机肥对川芎产量的互作效应达到了显著影响,中高水平的氮肥磷肥、氮肥有机肥、钾肥有机肥有利于川芎产量的提高。川芎高产的最优施肥方案为氮肥148.20~172.28 kg/hm^2,磷肥511.92~599.40 kg/hm^2,钾肥249.70~282.37 kg/hm^2,有机肥940.00~1 104.00kg/hm^2。结论:氮磷钾及有机肥配施会影响川芎产量,钾肥和有机肥会显著提高川芎的产量,建议适量多施钾肥和有机肥,适当增施氮肥。
Objective： To study the effects of different N,P,K and organic fertilizer（ OF） on yield of Ligusticum chuanxiong rhizome,in order to provide the theoretical foundation for the establishment of standardization cultivation techniques.Methods： The field plot experiments used Ligusticum chuanxiong rhizome which planted in Pengshan as material,and were studied by the four factors and five levels with quadratic regression rotation-orthogonal combination design.According to the data obtained,a function model which could predict the fertilization and yield of Ligusticum chuanxiong rhizome accurately was established.Results： The model analysis showed that the yields of Ligusticum chuanxiong rhizome were significantly influenced by the N,P,K and OF applications.Among these factors,the order of increase rates by the fertilizers was K〉 OF〉 N〉 P; The effect of interaction between N and K,N and OF,K and OF on the yield of Ligusticum chuanxiong rhizome were significantly different.High levels of N and P,N and organic fertilizer,K and organic fertilizer were conducive to improve the yield of Ligusticum chuanxiong rhizome.The results showed that the optimal fertilizer application rates of N was 148.20 ~ 172.28 kg / hm^2,P was 511.92~599.40 kg/hm^2,K was 249.70 ~ 282.37 kg/hm^2,and OF was 940.00~1104.00 kg / hm^2.Conclusion： N,P,K and OF obviously affect the yield of Ligusticum chuanxiong rhizome.K and OF can significantly increase the yield of Ligusticum chuanxiong rhizome.Thus it is suggested that properly high mount of K and OF and appropriate increasing N are two favorable factors for cultivating Ligusticum chuanxiong.
