摘　　要：通过叶分析研究了不同葡萄品种叶柄全钾5～9月含量动态变化规律。结果表明:葡萄叶柄钾含量在生育期内整体呈波浪式下降趋势,前期下降迅速,中期平缓,进入浆果成熟期后又趋于下降;强势品种在整个生长季节内对钾的吸收大于弱势品种;早熟品种叶柄内钾含量变化趋势比晚熟品种提前。根据新疆农五师葡萄园区土壤有效钾含量分布现状,建议生产中应根据葡萄钾元素动态变化特点,不同团场应结合当地土壤有效钾含量相应补充。Through analysis of leaves of different varieties of grape petiole 5~9 months of total K content in variation.The results showed that grape petiole potassium wavy in the growth period the overall downward trend,the rapid decline in early,mid flat,then tends to fall into the mature berries;strong varieties throughout the growing season than in the absorption of potassium vulnerable variety;early maturing varieties petiole potassium content within the trend earlier than late-maturing varieties.According to Park,Xinjiang Fifth Agricultural Division of soil available K content of grape current distribution,suggested the production of potassium should be based on the dynamic changes of grape,different mission field should be combined with the appropriate local soil potassium supplement.
