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。
The nutrient status, fruit quality and nutrient elements of three different types of soil in jujube orchard in Aksu were determined by correlation analysis and multiple linear stepwise regression analysis to screen the main soil nutrient factors that affect jujube fruit quality and nutrient elements. Jujube orchard to provide a scientific basis for scientific fertilization. The results showed that soil nutrient status of different soil types and jujube fruit quality and nutrient elements were different in different types of soils. Different soil nutrient factors had different effects on fruit quality, and soil nutrient status had no significant effect on fruit quality, Mineral nutrient content has a significant impact. The contents of available and available magnesium in soil were positively correlated with the content of soluble sugar in the fruit. The content of available nitrogen and available boron were negatively correlated with the titratable acidity in the fruit. The content of available potassium in soil was positively correlated with the content of potassium and magnesium in the soil. The available calcium content was negatively correlated with the content of magnesium in the fruit. The content of available magnesium in the soil was positively correlated with the content of manganese in the fruit, and the content of available magnesium in the soil was negatively correlated with the content of potassium in the fruit. , The available boron content in soil was negatively correlated with phosphorus in the fruit, the available iron content in the soil was positively correlated with the manganese in the fruit, the effective manganese was positively correlated with the manganese in the fruit, and negatively correlated with the phosphorus in the fruit.
