摘要
为筛选出既满足宜宾烟区井窖式小苗移栽又减少基质用量的育苗盘规格,采用湿润育苗的方式,研究了不同育苗盘规格对烟苗生长发育及烟叶产质量的影响。结果表明,128孔和162孔育苗盘所育烟苗生长较快,烟苗农艺性状、物质积累和合格烟苗率较高,大田烟株农艺性状、经济性状较高,但基质用量和所需育苗面积较大,育苗投入成本明显增加;200孔育苗盘所育烟苗素质、大田烟株农艺性状、经济性状等方面与128孔育苗盘相当,但其基质用量较128孔育苗盘降低39.88%,育苗盘面积较128孔育苗盘减少30.77%,育苗投入成本明显降低;288孔育苗盘虽然基质用量和所需育苗面积最低,但其所育烟苗素质,大田烟株农艺性状和经济性状显著低于其他处理。综合而言,200孔育苗盘是宜宾烟区比较理想的选择。
In order to screen out the seedling tray specifications which could not only meet the needs of well cellar type seedling transplanting in Yibin tobacco-growing area,but also reduce the amount of substrate and seedling rearing site,the effects of different seedling tray specifications on the growth and development of tobacco seedlings and tobacco yield and quality were studied by means of wet seedling rearing.The results showed that the seedlings grew faster in 128 pores per tray and 162 pores per tray,and the agronomic characters,material accumulation and qualified seedling rate were higher.The agronomic characters and economic characters of tobacco plants in the field were higher,but the amount of matrix and the required seedling area were larger,and the input cost of seedling rearing increased obviously.The quality,agronomic characters and economic characters of tobacco plants cultivated in 200 pores per tray were similar to that of 128 pores per tray,but the substrate consumption and the required seedling tray area were 39.88%lower than that of 128 pores per tray,30.77%lower than that of 128 pores per tray,and the cost of seedling rearing was significantly reduced.The seedling quality,agronomic characters and economic characters of tobacco plant in the field were significantly lower than those of other treatments,although the substrate consumption and seedling area required by 288 pores per tray were the lowest.In summary,200 pores per tray is an ideal choice in Yibin tobacco area.
