罗平土壤及烟叶主要中、微量元素含量分析
Contents of Major Medium and Micro Nutrients in Soils and Tobacco Leaves from Luoping
摘要
Abstract
The distribution characteristics and relationships of calcium, magnesium, sulfur, copper, zinc, iron, manganese and boron in 369 samples of soils and flue-cured tobacco (C3F) collected from Luoping were investigated. The results showed that the contents of calcium, magnesium, copper, zinc, iron, and manganese were sufficient, while sulfur and boron contents were relatively insufficient. There were widely spatial variability among soil available medium and micro nutrient contents. It is suggested to apply boron fertilizer during tobacco plant growth period. The average contents of sulfur, copper, zinc and manganese were in the ranges of high quality tobacco leaf production in China, but iron content was too high and calcium, magnesium and boron contents were too low. The nutrient contents in tobacco leaves were positively correlated with the nutrient contents in soil. Soil magnesium had promoting or inhabiting effects on medium and micro nutrients in tobacco leaves. Soil copper promoted the zinc uptake but inhibited boron uptake.关键词
