摘要
[目的]考查不同基质配比和不同浓度营养液在攀枝花湿润育苗中的作用。[方法]考查了不同基质和营养液浓度组合对烟苗出苗率、株高、干重、鲜重和叶面积的影响。[结果]在基质里添加30%的生土,配合福建龙岩生产的营养液,培育的烟苗健壮,茎高、茎围适中,根系发达,根系活力强,根茎叶干鲜重最重。[结论]适宜的湿润育苗基质配方为100%基质或基质添加生土30%。
[Objective]This paper in order to investigate the effect of different substrate ratio and different concentration of nutrient solution on moist tray seedling. [Method]The effect of different matrix and nutrient solution concentration on the tobacco seedling emergence rate,plant height,ect. [Result]Tobacco seedlings grow strong which have developed root system in the substrate adding 30% raw soil and nutrient solution produced in Longyan,Fujian. [Conclusion]The suitable moist tray seedling substrate are 100% substrate and the substrate adding 30%raw soil.
