枸杞总糖含量与环境因子的量化关系研究

A quantificational study on the relationship between saccharide content of medlar and surrounding factors

对我国北方6省区枸杞采样分析枸杞总糖与土壤养分和气象因素的定量关系研究结果表明,枸杞籽总糖含量受气象和土壤环境因子共同影响,其中土壤水解氮、速效钾、pH和有机质是影响枸杞总糖含量的主要因子。气象因子中果实形成期最高气温、最低气温、日照时数、降水量和全生育期积温均与枸杞总糖含量关系密切,且气象因子较土壤养分对总糖含量影响显著。

Based on the data of medlar sampling in Northern China,the quantificational relationships between saccharide content of medlar and soil nutrient,and meteorological factors were analyzed.The results show that saccharide content of medlar is determined by both soil nutrient and weather condition.Main factors which affected saccharide content of medlar include alkaline hydrolysis N,available K,pH and organic matter in soil,as well as weather condition during madlar fruits forming stage such as maximum temperature,minimum temperature,sunshine hours,rainfall and accumulated temperature,etc.Compared to soil nutrient,the weather factors have greater effect on saccharide content of medlar.
