枸杞糖碱成分及其与土壤肥力间的关系研究

Studies on the total sugar and betaine in Lycium barbarum L and their relationship with soil fertility factors

通过测定宁夏8个不同产区枸杞头茬果和盛果期果实中总糖、甜菜碱含量,研究枸杞中这两种成分的含量和比值变化以及它们与土壤肥力因子间的相互关系。结果表明:枸杞头茬果中总糖、甜菜碱含量均大于盛果期,而糖碱比在两茬间无显著性差异,但多数处于中糖中碱的优质枸杞范围内;土壤中的速效磷和速效钾是影响枸杞果实糖碱比的关键肥力因子。

The contents of total sugar and betaine in Lycium barbarum L from different regions of Ningxia at the first stubble and prosperous time were determined, in order to investigate the difference of contents in two picking stages and the correlation between contents and the soil fertility factors. The results showed that the contents in the first stubble fruits were both higher than those of prosperous time, however, the ratios of total sugar to betaine were of no significant difference, and the majority of ratios were appropriate. The vailable phosphorus and potassium were the key factors which affected the balance of total sugar and betaine.
