南方地区部分葡萄园营养状况分析

Analysis on Nutritional Conditions in Parts of Southern Vineyards

[目的]调查南方地区部分葡萄园的营养状况,为日后葡萄园的科学施肥提供参考依据。[方法]采集了南方地区有代表性的葡萄园土壤样本和叶片样本,并且对其营养状况进行分析。[结果]部分葡萄园土壤有机质含量不足,速效性铁、锰、铜、锌含量适宜,土壤pH较高的葡萄园存在缺镁的现象;南方地区葡萄园叶片氮、磷、钾含量适宜,个别地区缺钙,缺镁现象很严重。[结论]重视有机肥的施入,着重补充镁元素。

[Objective] The aim was to investigate nutritional status of the southern parts of vineyard,and provide the reliable basis for scientific fertilization.[Method] Samples of soil and leaf from the southern part of representative vineyards were collected,and the nutrition status were analyzed.[Result] Parts of the vineyard organic matter content of the soil is insufficient,effective iron,manganese,copper,zinc is appropriate,the vineyard with higher soil pH value exists the phenomenon of lack of magnesium; The nitrogen,phosphorus,potassium content in leaf petiole is appropriate in southern vineyard,individual serious calcium and magnesium deficiency.[Conclusion] Attaches great importance on the organic fertilizer and magnesium supplement.
