【摘要】 针对贺兰山东麓酿酒葡萄风沙土产区中微量营养元素相对缺乏,空间变异较大等限制产业高效发展的关键问题,以4年生"蛇龙珠"葡萄为试材,通过设置滴灌施肥试验,研究了中微量营养元素钙(Ca)、镁(Mg)、铁(Fe)、锰(Mn)、铜(Cu)、锌(Zn)、硼(B)元素对酿酒葡萄生长及品质的影响。结果表明:增施中量元素Mg能有效提高葡萄叶片和叶柄中的全磷含量进而提高葡萄单粒重及产量,同时能提高果实单宁及总酚含量;增施微量元素Fe有利于促进叶片的生长发育,提高叶片净光合速率并促进干物量积累,增加可溶性糖含量;增施B元素则能有效提高叶片和叶柄的全钾及果实中花色苷含量。综合分析,增施Fe、Ca元素能促进葡萄的生长,增施B、Mg元素能提高酿酒葡萄果实品质,增施Ca、Mg元素能更好的提高酿酒葡萄产量。更多还原

【Abstract】 There was large area of wine vineyards at the Eastern foot of Helan Mountain,and the wine grape industry has become the main industry here.However,many reasons,such as the lack of the secondary and micro-element,the space etc,severely restrict the development of this industry.With 4-year-old ‘Cabernet Gernischt’grape as material,the influence of the micro-elements Ca,Mg,Fe,Mn,Cu,Zn,B on the growth and quality of the wine grape by the experiment on fertigation by drip irrigation was studied.The results showed that the increasing amount of the Mg could improve the total phosphorus content of the leaves and petioles of the grape,and the single weight of the grape,while improve the tannins and the total phenols content,but the fertilizer effect of Cu was not obvious.Meanwhile,the element Fe was beneficial to promote the growth and development of the blade,improve leaf net photosynthetic rate and promote the amount of dry matter accumulation,increasing the soluble sugar content.The element B could improve the total potassium and fruit anthocyanin content of leaf and petiole,but the fertilizer effect of Mn and Zn were not obvious.In conclusion,the elements Fe and Ca could promote the growth of grapes,the elements B and Mg could improve the quality of the wine grape,the elements Cu,Ca and Mg could improve the wine grape production better.更多还原
