舟曲野生紫斑牡丹扦插成效初报

A Result Report on Cutting Experiment of Wild Paeonia rockii in Zhouqu,Gansu

舟曲县野生紫斑牡丹自然更新弱,播种、分株和嫁接育苗均存在限制因素。以舟曲县野生紫斑牡丹为材料,开展室内室外环境、日期、生根剂处理3因素多水平全交叉扦插试验。结果表明:8月份室外扦插,吲哚丁酸、ABT1号生根粉600 mg/L浸泡插穗3 min,样穗生根成活效果最佳。圃地施入农家肥15 t/hm^(2)为基肥,高锰酸钾溶液0.05%喷洒土壤消毒,吲哚丁酸或ABT1号生根粉600 mg/L浸泡插穗3 min,8月份室外扦插,搭建塑料膜小棚并遮光率40%,每2周洒水1次,每周揭棚查看并喷施农药杀菌杀虫,50 d成活率可达70%,平均生根可达16条/穗,可以用于紫斑牡丹扦插育苗生产。

Natural regeneration of wild Paeonia rockii was weak in Zhouqu County,and there were limiting factors in sowing,dividing and grafting.In this study,three factors,including indoor and outdoor environment,date and rooting agent treatment,were used to carry out the cross-cutting experiment of wild Paeonia rockii spot in Zhouqu County.The results showed that when the cuttings were cut outdoors in August and indolebutyric acid and ABT1 root powder were soaked for 3 min,the root survival effect of the sample panicles was the best.Apply farm manure 15 t/hm^(2)as the base fertilizer,spray 0.05%potassium permanganate solution for soil disinfection,indolebutyric acid or ABT1 root powder 600 mg/L soak cuttings for 3 min,cut cuttings outdoors in August,build plastic film shed and shading rate of 40%,spray water every two weeks,open shed to check and spray pesticides every week for sterilization and insecticide.The survival rate was 70%after 50 days,and the average rooting rate was 16 per panicle,it's appropriote for cutting seeding productin of wild paeonia rockill.
