宁夏贺兰山东麓酿酒葡萄肥料配比效应研究

Effect of different fertilizer proportion on grapevine at eastern foot of Helan Mountain of Ningxia

运用正交试验设计研究了宁夏贺兰山东麓酿酒葡萄基地不同氮、磷、钾肥料配比对酿酒葡萄新梢长度、产量和品质的影响。结果表明,酿酒葡萄在不同生育期对N、P、K营养元素的需求有较大差别:6月份N1P3K2为最佳肥料配比组合,即施N 0.1 kg/株,施P2O5 0.3 kg/株,施K2O 0.2 kg/株;7月份N1P2K3为最佳组合;8月份N3P2K3为最佳组合。N2P3K1配比为高产施肥组合,而N3P3K3的肥料配比是获取高糖含量的最佳组合。三要素中钾的产量和品质效应最高,且对产量与品质的影响一致。

Shoot length, yield and quality of wine grape with different proportions of N, P, K fertilizers were studied by orthogonal experiment design at eastern foot of Helan Mountain. The results showed that wine grape during growing period need quite different quantity and type of N, P, K nutrients. N1P3K2 treatment was the best proportion of N, P, K fertilizers in June, N1P2K3 and N3P2K3 treatment was the best in July and August respectively. N2P3K3 treatment was the best for heightening yield, and N3P3K3 treatment was the best for improving sugar content. K has the highest effectiveness and coherence on both yield and quality among N, P, K nutrients for wine grape growth.
