Abstract: In order to solve the problems of less oil and stiff structure of Yunyan 97 tobacco leaves, especially the upper leaves, the field experiment of soybean milk root irrigation was carried out in southern Anhui tobacco growing area.The physical properties, economic properties, chemical composition and sensory quality were analyzed. The results showed that treatment C (75kg/hm2 soybean milk root irrigation) had the best comprehensive performance, and the index values were significantly higher than those of the control, which could effectively improve the quality and availability of upper tobacco leaves.

烤烟豆浆灌根是将豆浆浇灌于烟株根系旁边的穴中,是起源于河南三门峡烟区的一项生产技术措施。烤烟豆浆灌根技术能有效提升烟叶产质量,叶片油分增多;颜色多橘黄,光泽强而鲜亮,均匀度好;结构疏松;身份适中,手感绵软,弹性好;香气优雅,闻香突出[1]。由于长期施用单一肥料,土壤有机质含量下降,使得我国烟叶营养比例失调,油分少,香气量不足[2-4]。适量的豆浆灌根能够显著改善烤烟各部位叶片的物理特性,优化叶片主要化学成分指标,有效提高烟叶的可用性,改善烟叶品质,增加种烟经济效益[5]。本研究旨在通过探究豆浆灌根对上部高成熟度烟叶品质的影响,以期改进当前皖南烟区云烟97烟叶尤其上部叶油分偏少、结构僵硬的现状。
1 材料與方法
1.1 供试材料 供试品种:云烟97;供试地点:安徽省宣城市宣州区沈村镇丁店村。
1.2 试验设计 试验共设4个处理:A:不灌根(CK);B:豆浆灌根45kg/hm2;C:豆浆灌根75kg/hm2;D:豆浆灌根105kg/hm2。2020年在安徽宣州区丁店村开展豆浆灌根的大田试验,将黄豆用水浸泡,然后用豆浆机打浆或磨成粉状,再慢慢加水搅拌成浆。……
