北京昌平苹果园土壤养分、pH与果实矿质营养的多元分析
Multivariate analysis of relationship between soil nutrients, pH and fruit mineral nutrition in Fuji apple orchards of Changping, Beijing
摘要
Abstract
The investigations were conducted with soil nutrient contents, pH and mineral nutrition contents in fruits at 34 adult apple orchards in Changping district of Beijing from 2008 to 2009. The methods of multivariate statistics were used to probe into optimum proposal of soil nutrition, pH factors for high mineral element contents of fruit. The results showed that soil organic matter (SOM) had separately positive correlation with all soil mineral elements, and there were weak correlation between soil nutrient contents and mineral element contents of fruit. Simple factor correlation analysis could not really explain relationship between soil nutrient contents and mineral nutrition contents of fruit. The canonical correlation analysis was used to obtain important impact SOM and pH on mineral element content of fruit. The optimum proposal of soil nutrient contents, pH for high mineral element contents of fruit were obtained that SOM was 27.62 to 40.00 g·kg-1, total N greater than 3.00 g ·kg-1, alkaline N greater than 100.00 mg ·kg-1,available P 140.68 to 550.00 mg·kg-1, available K 293.60 to 650.00 mg·kg-1, available Ca 1.75 to 3.04 rog·kg-1, available Fe 15.00 to 60.00 mg·kg-1, available Zn 4.00 to 20.00 mg·kg-l, available B 0.50 to 2.00 mg· kg-1 and pH 6.49 to 7.50. The key technical strategies for soil management of orchard in Changping were to improve available Keontents in soil and adjusting soil pH.关键词
