骏枣叶片营养与土壤肥力及产量模型的建立
Establishment of the Model Involving the Blade Nutrition of Jun Jujube, Its Soil Fertility and Yield
摘要
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 R2 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.关键词
