摘要
为探究山东道地金银花品质与土壤肥力的关系,在山东省临沂市平邑县和费县,选取100个代表性土壤样点,点对点进行土壤质量和金银花品质的调查分析。根据土壤pH、CEC、有机质、有效磷、速效钾、全氮、全磷、全钾、有效铁、有效锰、有效铜、有效锌、有效硼和土壤质地类型等土壤肥力评价指标,采用这些指标与金银花长势和品质指标的相关系数来确定各项指标的权重,计算土壤综合肥力指数,分析土壤肥力因子与金银花生长和品质的关系。结果表明:调查区域金银花种植土壤全氮和有效磷含量较丰富,有机质和速效钾含量较为缺乏;土壤综合肥力指数在0.20~0.75,平均为0.45,总体肥力偏低。土壤肥力综合指数与金银花冠幅呈显著正相关,土壤有效硼含量是影响土壤肥力的主要限制性因子,最适合金银花生长的土壤类型是砂壤土。金银花绿原酸含量与土壤全磷含量呈正相关关系,木犀草苷含量与土壤全氮含量以及土壤综合肥力指数呈负相关关系。总体上看,肥力指标较低的砂壤土更有利于金银花品质的提升,这也可能是调查区道地金银花品质总体比较好的原因。本研究结果对当地金银花种植土壤选择、规范化种植和养分管理有一定的参考和指导作用。
In order to investigate the relationship between the quality of Chinese honeysuckle in genuine producing area and soil fertility,100 representative soil samples were collected from Pingyi County and Fei County in Linyi City of Shandong Province and used for the point-to-point survey and analysis of soil and honeysuckle quality.Based on the evaluation indexes of soil fertility(such as soil pH,organic matter,available phosphorus,rapidly available potassium,total nitrogen,total potassium,available iron,available manganese,available zinc,available boron and soil texture),soil integrated fertility index(IFI)was calculated to analyze the relationship between soil fertility indexes and honeysuckle growth and quality indexes.Results showed that soils for honeysuckle planting in the study area were rich in total nitrogen and available phosphorus but deficient in organic matter and rapidly available potassium.Soil IFI was ranged from 0.2 to 0.75 with an average of 0.45,which indicated a low soil fertility.Positive correlation existed between soil IFI and honeysuckle crown.Besides,soil available boron was the main limiting factor of soil fertility and sandy loam was the most suitable soil type for honeysuckle growth.Chlorogenic acid content in honeysuckle had positive correlation with soil total phosphorus but galuteolin content had negative correlation with soil total nitrogen and soil IFI.Overall,sandy loam with lower IFI was more beneficial for improving honeysuckle quality which might be the reason why honeysuckle showed good quality in the study.This study can provide certain references and directions for soil selection,standardized planting,and nutrition management in local honeysuckle production.
