【摘要】 为减少目前烤烟漂浮育苗对草炭的依赖,开展了完全替代草炭的新型育苗基质研究,并就筛选出的两种基质与目前使用的基质(对照)进行了育苗、田间对比试验。结果表明:两种基质对烤烟种子的出苗期与对照相比基本无影响,但出苗后T1的长势最差,T2与对照的差异不大。出苗率以对照最高,其次为T2,T1的出苗率最差;T2的烟苗素质与对照相当,且优于T1,主要体现在烟苗的侧根数目上。T2的产量、产值、均价、上等烟率等经济性状表现最高,但与对照的差异不显著。更多还原

【Abstract】 To decrease the reliance on peat of flue-cured tobacco seedling, the new type medium which substituted completely the peat in the substrate formula was studied in the seedling test and field test. The results showed that the seedling stages of 2 new mediums were the same of the check, and the growth and development of seedling of T1 was the worst, the difference of T2 and check were not obvious. The seedling ratio of the check was ranked the first, that of the T2 was the second, and that of the T1 was the last. The matured seedling diathesis quality of the T2 and check, with more lateral roots, was better than that of the T1. The yield, produce value, average price super class leaf ratio, high and middle grade leaf ratio of the T2 were the highest, but contrasted with the check, the difference was not significant.更多还原
