摘要
为了加速大石早生李的苗木生产，应用植物生长调节剂进行了嫩枝扦插育苗试验。结果表明，选择长１５～２５ｃｍ、顶部带３～４个叶片的半木质化嫩枝，用２５０ｍｇ／Ｌ萘乙酸溶液处理插穗基部３０ｓ，在扦插床内保持温度２５～２８℃、湿度８５％以上、３０％的透光率，生根率可达８７％，扦插４５ｄ后，移栽成活率可达９５％以上。于５～９月份不同时间扦插，以８月份生根率最低，其他月份生根率较高且差异不明显。
For speeding up the production of planting stock of Dashi early ripening plum ,the experiments on softwood cuttage were conducted with plant growth regulators.The rooting rate of 87% were obtained 45 days after cuttage using the half lignified green twigs with 3～4 leaves,treated with NAA 250 mg/L for 30 seconds ,cultured in cutting bed under 25～28℃,relative humidity over 85% and transparency 30%.For the rooted cuttings the survival rate after transplanting was as high as 95%. All the cuttings collected during the period of May to September gave comparative high rooting rate with no significant difference except those collected in August.
