摘要
本试验测定四个枸杞果园O～40cm土层的营养状况，分析了相应果园枸杞果实的主要品质，经多元线性逐步回归分析结果表明，在一定范围内，枸杞果实的总糖、总酸含量与土壤盐分含量呈线性正相关，与速效磷呈线性负相关；类胡萝卜素含量与碱解氨、速效磷均呈线性负相关；可溶性蛋白质与速效磷和pH均呈线性负相关；Vc含量与土壤碱解氮含量呈线性正相关，与速效钾呈线性负相关；多糖与速效磷呈线性负相关，与盐分呈线性正相关。
The soil nutrient status. （0-40 cm） of four Lycium barbarum orchards were determined,and their fruit qualities were analyzeel respectively by the multiple linear stepwise regression analysis, Results showed that among a certain range, the total sugar and total aeid were positive correlated with the content of soil salt, but were negatively correlated with the content of available P; the carotenoid contents was negatively with the content of soil alkalization nitrogen and available P; the contents of soluble protein was negatively corralated with the content of available P and soil pH;The Vc content was positive correlated with.the content of soil alkalization nitrogen, but negatively with content of available K;The contents of polysaccharomyces was negatively correlated with available P, but positive correlated with the content of soil salt.
