贺兰山东麓酿酒葡萄叶片、叶柄营养诊断及分析

Nutrition Diagnosis and Analysis of Leaves and Petioles of Wine Grapes at the Eastern Foot of Hel⁃an Mountain

以宁夏贺兰山东麓主栽的7年生‘梅鹿辄’和‘赤霞珠’的叶片为研究对象,通过对贺兰山东麓不同产区酿酒葡萄‘梅鹿辄’和‘赤霞珠’叶片进行营养诊断,分析研究高产园和低产园中酿酒葡萄叶片的大量、中量及微量元素营养状况。结果表明,在高低产园中,‘梅鹿辄’和‘赤霞珠’的叶片养分含量差异较大,微量元素含量>大量元素含量>中量元素含量。

In this paper,the leaves of 7~year old merlot and Cabernet Sauvignon planted in the eastern foothills of Helan Mountain in Ningxia Were taken as the research object.Through the nutritional diagnosis of the leaves of wine grape merlot and Cabernet Sauvignon from different producing areas in the eastern foothills of Helan Mountain,the nutritional status of large,medium and trace elements in wine grape leaves in high~yield and low~yield gardens was analyzed and studied.The results showed that the differences of leaf nutrient contents between Merlot and Cabernet sauvignon in high and low gardens were as follows:trace element content>mass element content>medium ele⁃ment content.
