【摘要】 以悬铃木无果品系为接穗,研究了其规模化嫁接生产技术。结果表明:在无果悬铃木苗圃建设初期,以尚未栽植的胸径4～6cm的独干悬铃木为砧木,采用砧木树干覆膜保湿处理和在地面上进行嫁接后再进行栽植的关键技术,实现了"先嫁接后栽植"的技术流程,减少了架梯高接的繁琐操作,缩短了单株嫁接时间,大大提高了工作效率。砧木成活率可达96.67%,比树干不覆膜的砧木成活率提高了53.33个百分点;嫁接成活率可达94.78%,比树干不覆膜提高了52.51个百分点。更多还原

【Abstract】 Taking the fruitless P.acerifolia as scion,large-scale grafting technology of fruitless Platanus acerifolia Willd.were studied.The results showed that at the first stage of nursery construction,the key technology of coating stem and grafting early to planting was used to not planting stocks with monopode and 4~6 cm diameter at breast height could reduce the operation of putting up ladder and save grafting time.Stocks survival rate was up to 96.67%,which was of 53.33 percent point higher than no coating stem.Grafting survival rate was up to 94.78%,which was of 52.21 percent point higher than no coating stem.更多还原
