不同砂质砂培漂浮育苗对烤烟烟苗及其产质量的影响
Journal of Yunnan Agricultural University(Natural Science)（2011）
Abstract
为确定适宜的育苗用砂质基质,以草炭、蛭石和腐殖酸为材料的传统基质材料为对照,进行丽江市永胜县当地的砂质山砂、热河河砂和金砂江江砂3种砂质基质与材料对烤烟砂培育苗成苗的影响研究.结果表明:烟苗的出苗率和成苗率,金砂江江砂和热河河砂处理的与现行漂浮基质接近.壮苗率接近或超过现行漂浮苗.热河河砂低于对照2％,金砂江江砂高于对照1.7％.热河河砂和金砂江江砂的烟苗根系发育良好,地上部与地下部比例协调,烟苗生长及素质好,而砂质山砂处理稍差.3种砂质处理烟苗的指标均在壮苗要求范围内,且成本投入低于现行漂浮苗33.1％.
