摘要
为探索永州烟区烤烟适宜的育苗方式,提升育苗技术水平,本研究以‘云烟87’作为供试品种,对喷淋育苗(T_(1))、浅水育苗(T_(2))、浅水+纤维棉湿润育苗(T_(3))、漂浮育苗(T_(4))这4种不同的育苗处理方式展开对比研究。系统分析了不同育苗方式对烟苗素质、根系、生物量、壮苗指数,以及烤烟大田生育期、农艺性状、经济性状和化学成分等方面的影响。研究结果显示,在烟苗阶段,浅水+纤维棉湿润育苗处理呈现出诸多优势。该处理下的烟苗出苗率高达100%,生育期提早5 d,生长势强劲,素质优良,根系表现出色。烟苗综合素质的排序为T_(3)>T_(2)>T_(4)>T_(1)。进入大田期后,T_(3)处理的烟苗在株高、茎围、有效叶数、最大叶面积等综合农艺性状方面表现最为突出,综合农艺性状的优劣顺序为T_(3)>T_(2)>T_(1)>T_(4)。同时,浅水+纤维棉湿润育苗处理的烟苗在经济性状和化学成分协调性上均表现最佳。综上所述,浅水+纤维棉湿润育苗能够显著提高烟苗素质,适宜在永州烟区进行推广。
To explore suitable seedling cultivation methods for flue-cured tobacco in Yongzhou tobacco-growing areas and improve seedling techniques,a comparative study was conducted using the cultivar‘Yunyan 87’under four treatments:spray seedling(T_(1)),shallow water seedling(T_(2)),shallow water coupled with fiber cotton moist seedling(T_(3)),and floating seedling(T_(4)).The effects of different methods on seedling quality,root system,biomass,strong seedling index,field growth period,agronomic traits,economic characteristics,and chemical components were systematically analyzed.Results showed that T_(3) treatment achieved the highest seedling emergence rate(100%),shortened the growth period by 5 days,and exhibited superior growth vigor,seedling quality,and root performance,with overall seedling quality ranking as T_(3)>T_(2)>T_(4)>T_(1).During the field growth stage,T_(3) demonstrated optimal comprehensive agronomic traits,including plant height,stem circumference,effective leaf number,and maximum leaf area,with the ranking as T_(3)>T_(2)>T_(1)>T_(4).Furthermore,T_(3) displayed the best coordination of economic traits and chemical components.These findings indicate that shallow water coupled with fiber cotton moist seedling cultivation significantly enhances seedling quality and is suitable for promotion in Yongzhou tobacco-growing areas.
