摘要
以顶果木半年生优势苗作为采穗母株,研究了嫩枝扦插育苗技术。结果表明:截干高度对母株产穗量影响显著,最适宜截干高度为20～30cm;生根促进剂浓度对插穗生根影响显著,采用GGR的适宜浓度为800～1 000mg/kg;扦插时间同样影响插穗生根,一年中适宜的扦插时间为3—7月。
This paper chooses half a year old Acrocarpus fraxinifolius advantage seedlings as ortet,and systematic studies the technique of soft branch cutting.The test showed：truncation height had significant influence to the number of stump plant,the best truncation height was 20-30 cm;The concentration of root accelerant had significant influence to the rootage rate,the best concentration was 800-1000 mg/kg;The time of cutting had significant influence to the rootage rate,the best time was March to July.
