摘要: 采用长8-10cm,茎粗0.4-0.7cm的半木质化枇杷嫩枝插条,针对不同枇杷品种,基部分别用200ppmIBA或200ppmNAA溶液浸泡3/小时后扦插于适宜基质的插床上,保持温度20-30℃,相对湿度85%以上,并用间歇弥雾处理等综合配套技术,扦插2246株,经45天后,长根率达91%.其中未长根的嫩校经200PPmIBA溶液重复处理0.5小时扦插30天后长根率达88%.植株移栽成活率达99%.扦插1年即可出圃,比常规嫁接育苗法提早1年左右.Abstract: The half-xyloid tender branches of loquat with 8-10cm long and 0.4-0.7cm in diameter were employed for cultage in the suitable seedbed after soaking the branches base in 200 ppm IBA or 200 ppm NAA for 3 hours 2ccording to varying varieties,respectively.The air temperature and humidity were retained in 20C-30 C and over 85%, respectively.The treatment of fine spray as well as other comprehensive techniques were used.2246 tender branches were cuttaged and the growing root was 91% in 45 days.The transplanting survival rate of these growing root seedlings was 99%.The remaining branches without growing roots were treated repeatly by 200 ppm IBA for half hour and the growing root rate were 88.0% after 30 days.The time of raising seedlings by tender branch was one year shorter than that by graftage.
