成渝地区葡萄园营养状况初步研究与分析

摘要

在成渝地区具有代表性的葡萄园内进行了叶样和土样采集分析,结果表明:与标准值对比,大部分葡萄园内叶片中营养元素P与Mg含量水平较低,微量元素Mn与Fe含量水平则偏高；在大量使用有机肥的葡萄园内,土壤中速效性的营养元素N、P、K含量水平相对较高.%Leaf and soil samples collected from some representative vineyards in Chengdu and Chongqing areas were tested and analysed. The results showed that values of Phosphorus and Magnesium in leaf petiole samples from the most vineyards were lower than diagnostic creteria, but values of microelements of Manganase and Iron were higer than the creteria. In vineyards fertilized with organic matter largely, the values of effective nutrient elements of Nitrogen, Phosphorus and Potassium in soil were relatively higher than normal vineyards.
