摘要
对攀枝花烟区湿润育苗的几个关键技术进行了试验分析。结果表明,商品化草炭基质与黄泥土按7∶3(质量比)混配制作育苗基质、2月中下旬至3月上中旬播种所育烟苗综合素质最高,茎高、茎围适中,根系发达,根系活力高,抗旱性强;与漂浮育苗相比,湿润育苗技术提高了成苗期烟苗的素质,有效地解决了返苗期偏长的问题。
The key techniques of tobacco moisture breeding in panzhihua tobacco planting area were experimentally analyzed.The results showed that if using mixed commercial peat substrates and loess with mass ratio of 7∶3 as breeding substrate,sowing from late February to early and middle March,the tobacco seedling had the highest overall qualities,the stem height and girth was moderate,the root system was strong and with high vigor,resistant to draught.Compared to floating breeding,the technique of moisture breeding raised the quality of tobacco seedling,solved the problems of long recovery growth stage.
