不同施氮量对烤烟新品种KRK26产质量的影响

摘要

通过对烤烟新品种KRK26进行肥料梯度试验,探讨了在不同的施氮水平条件下对烟叶生长发育、产量及质量的影响.结果表明,KRK26田间长势较旺,整齐度好；KRK26成熟烟叶表现为较易烘烤,与对照云烟87相当,原烟成熟度好,颜色以橘黄色为主,身份适中至稍薄、油份多、弹性强；KRK26内在化学成分较对照云烟87更加协调；KRK26产量产值均比对照云烟87高.以每公顷施纯氮129kg的处理综合性状表现最佳.%The effects of nitrogen application rate on the growth, development, yield and quality of new flue - cured tobacco variety KRK26 were studied through field fertilizer gradient experiments. The results showed that KRK26 grew vigorously and uniformly in the field. The mature leaves of KRK26 were easily baked, which was similar to the check variety Yunyan 87. The raw tobacco of KRK26 had good maturity, orange color, moderate ~ slightly thin body, much oil content and strong flexibility. The inner chemical components of KRK26 were more coordinative than those of Yunyan 87. KRK26 had higher yield and production value than Yunyan 87. The application of 129 kg pure nitrogen per hectare could obtain the best overall performance of the characters.
