| 摘 要： | 测定了4个不同品种(系)榛树叶片中的营养元素含量,以探索榛树生长不良的原因。结果表明:榛树体内存在矿质营养失衡现象,叶片表现黄化的品种的Ca和Cu的含量相对较低。相关性分析结果表明,20~40 cm土壤中的K与叶片中的Cu、Mn呈极显著正相关(p<0.01)。

The Determination and Analysis of the Nutritional Elements Content in Leaves of Hazelnuts and Soils |
| |
| Abstract: | In this experiment,contents of nutritional elements were assayed in leaves of four hazelnut cultivars or lines and soils,in order to find out the reasons for poor growth of hazelnut trees and soils.The results showed: Out-of-balance of nutritional elements in hazelnut trees were existed,Ca and Cu contents of etiolated hazelnut cultivar were lower than the others.Correlation analysis indicated that content of K in soils in 20～40 cm was positively correlated with the contents of Cu and Mn in leaves(p<0.01).Applying more K fertilizer in fitting ranges can promote photosynthesis,enhance the nutrition,and prevent etiolation effectively. |
