研究土壤养分与骏枣品质之间的相关性,是骏枣科学合理施肥、改善品质的基本依据。通过同步采集土壤与骏枣果实样品,室内化学分析土壤养分、骏枣品质指标,研究了土壤全氮、全磷、全钾、有机质、p H、速效磷、速效钾对骏枣总糖、总酸的影响。结果表明:骏枣果实品质与土壤养分存在显著性相关关系,其中总糖含量与土壤中速效钾和有机质含量成显著正相关,相关系数R分别为0.830 3和0.811 4。土壤光谱能较好的预测土壤养分,相关系数R在0.78⁰.89之间。

Studying the correlation between soil nutrients and Jun Jujube quality is the reasonable for Jun Jujube's scientific fertilization,and the fundamental basis for improving its quality. By sampling the soil and Jun Jujube fruit at the same time,analyzing the of nutrients and the Jun Jujube's quality index,the effects on the Jun Jujube's total sugar and total acid by the soil total nitrogen,total phosphorus,total potassium,organic matter,p H,available phosphorus and potassium were determined. The results showed that the Jun Jujube fruit qualities were significantly correlated with soil nutrients,and the total sugar content was significantly positive correlated with the soil available potassium(R = 0. 8303) and organic matter content(R = 0. 8114). Soil nutrients could be predicted by the spectrum of soil with the correlation coefficient R between 0. 78 and 0. 89.
