对主栽品种青岛大花在不同生育期所需8种营养元素进行了分析,其含量N、P、Cu在引蔓期最高,膨大期最低;Ca、Mg、B在引蔓期最低,膨大期最高;K在上架期最高,膨大期最低;Mn在上架期最低,膨大期最高。通过养分指数的计算,Ca在各生育期处于严重不足状态;Mn、B、Cu、Mg已成为啤酒花发展的限制因子。基于此,通过叶面喷施螯合性氨基酸肥料对所缺乏的元素进行调节,取得了一定效果,为啤酒花的优质高产探索了一条好的途径。
The results showed that the contents of N, P and Cu were the highest in the lead-inducing period and the lowest in the expanding period, while Ca, Mg and B were the lowest in the lead-inducing period. The highest period of K; K in the shelves of the highest expansion of the lowest; Mn shelf in the lowest, the highest expansion period. Through the calculation of nutrient index, Ca is seriously deficient in all growth stages; Mn, B, Cu and Mg have become the limiting factors in the development of hops. Based on this, foliar application of chelating amino acid fertilizers on the lack of elements to adjust, and achieved some results, hops for high quality and yield to explore a good way.
