我国金银花产质量影响因素分析及轻简化施肥推荐

Factors Influencing Yield and Quality of Lonicera japonica and Simplified FertilizationRecommendation in Our Country

金银花是我国一种用途广泛的传统大宗中药材,年需求量大,影响其产量和质量的因素较多。本文通过文献检索,从产地特点、品种特性、土壤性质、管理措施及加工方式等方面对影响金银花产质量的主要因素进行了综述;并通过引入结构方程模型,探索性地分析了不同因素对金银花产量的相对影响程度。结果发现,对于某一产地的具体品种,单株产量的主要影响因素是土壤有机质含量、pH值和速效钾含量等土壤因素和施氮量等施肥因素。在此基础上,针对当前施肥现状进行了以干花重为基准的施肥量推荐,并借鉴根区施肥法,提出了将全年所需肥料一次性施于根区的轻简施肥法,旨在为金银花轻简化高产高效优质栽培提供思路与参考。

Lonicera japonica Thunb.is a kind of widely used traditional Chinese medicinal herb in China,with a large annual demand.There are many factors that affect its yield and quality.Through literature search,this paper reviewed the main factors influencing the yield and quality of L.japonica from the aspects of producing area characteristics,variety characteristics,soil properties,management measures and processing methods;the exploratory analysis was conducted on the relative influence degree of different factors on the yield of L.japonica by introducing the structural equation model.The results showed that,for specific varieties in a certain producing areas,soil factors(such as soil organic matter content,pH value and available potassium content)and fertilization factors(such as nitrogen application rate)were regarded as the main influencing factors on the yield per plant.On this basis,in view of the current fertilization situation,the recommended fertilizer amount based on dry flower weight was proposed.And a simplified fertilization method that applied all the fertilizers required in the whole year to the root zone at once was proposed by drawing on the root zone fertilization method,so as to provide ideas and references for the simplified cultivation of L.japonica with high yield,efficiency and quality.
