【摘要】：测定阿克苏地区骏枣果园3种不同类型土壤的养分状况、果实品质及营养元素,进行相关性分析及多元线性逐步回归分析,以筛选影响骏枣果实品质和营养元素的主要土壤养分因子,为骏枣果园科学施肥提供理论依据。结果表明,不同土壤类型的土壤养分状况及在不同类型土壤生长的骏枣果实品质及营养元素均存在较大差异;不同土壤养分因子对果实品质影响作用不同,土壤养分状况对骏枣果实品质和矿质营养含量具有显著的影响。土壤中有效钙、有效镁含量与果实中的可溶性糖呈正相关,速效氮、有效硼含量与果实中的可滴定酸呈负相关;土壤中速效钾含量与果实中的钾和镁呈正相关;土壤有效钙含量与果实中的镁呈负相关;土壤中有效镁含量与果实中的锰呈正相关,土壤中有效镁含量与果实中的钾呈负相关;土壤中有效硼含量与果实中的钾呈正相关,土壤中有效硼含量与果实中的磷呈负相关;土壤中有效铁含量与果实中的锰呈正相关;有效锰与果实中的锰呈正相关,而与果实中的磷呈负相关。
[Abstract]:The nutrient status, fruit quality and nutrient elements of three different types of soil in Junzao orchard in Aksu area were determined, and the correlation analysis and multiple linear stepwise regression analysis were carried out. In order to select the main soil nutrient factors affecting the fruit quality and nutrient elements of Junzao, this paper provides a theoretical basis for scientific fertilization in Junzao orchard. The soil nutrient status of different soil types and the fruit quality and nutrient elements of Jujube grown in different soil types were different, and the effects of different soil nutrient factors on fruit quality were different. Soil nutrient status had significant effect on fruit quality and mineral nutrient content of Junzao. Available calcium and available magnesium in soil were positively correlated with soluble sugar in fruit, available nitrogen and available boron were negatively correlated with titratable acid in fruit. The content of available potassium in soil was positively correlated with potassium and magnesium in fruit, the content of available calcium in soil was negatively correlated with magnesium in fruit, the content of available magnesium in soil was positively correlated with manganese in fruit, and the content of available magnesium in soil was negatively correlated with potassium in fruit. There was a positive correlation between available boron content in soil and potassium in fruit, negative correlation between available boron content in soil and phosphorus in fruit, positive correlation between available iron content in soil and manganese in fruit, and positive correlation between available manganese and manganese in fruit. There was a negative correlation between phosphorus and phosphorus in fruit.
