| 摘 要： | 目的]建立骏枣坐果期叶片营养元素含量与土壤养分以及叶片养分、土壤电导率与产量之间的回归模型.方法]分析测试骏枣坐果期叶片营养元素含量、土壤养分、土壤电导率,调查骏枣完熟期的产量,分析其中的相关回归关系.结果]骏枣坐果期叶片营养元素含量与土壤养分之间关系密切；土壤电导率与果实产量之间达到显著相关水平,决定系数R2为0.596 3,表明应用土壤电导率建立产量预测模型可以得到较好的结果.结论]充足的土壤养分是实现高产的保证,通过人为合理的控制施肥,以达到优质高产的目的.

| Abstract: | Objective]To establish the regression model among the nutrient element content of blade in jun jujube fruit stage,soil nutrient and blade nutrient,soil conductivity and yield.Method]Through the analysis and test of the nutrient element content of blade in jun jujube fruit stage,soil nutrient,soil conductivity,the production yield in jun date full ripeness period was surveyed and the relationship among themselves was analyzed.Result]The nutrient element content of blade in jun jujube fruit stage was closely related to the soil nutrient;Soil conductivity and fruit yield present were significantly correlated.Its determination coefficient R is 0.596 3,which suggests that we can get better results by using the soil conductivity to establish yield prediction model.Conclusion]Plenty of soil nutrient is assurance of high yield,and we can achieve the purpose of high quality and high yield through the reasonable control fertilization. |
