摘要
[目的]研究核桃硬枝生根无性繁殖技术.[方法]以1~3年生鲁核1号、香玲嫁接苗、黑核桃和野核桃实生苗为试材,采用核桃苗平栽、平埋及70 mg/kg生根粉(ABT1号和ABT3号)处理的方式进行无性繁殖技术研究.[结果]在新梢长出3~4对复叶时,首次沿新梢基部浇施浓度为70 mg/kg的ABT1号生根粉液,间隔30 d处理1次,共处理3次,生根效果最好.[结论]研究方法操作简单、成本低、所繁苗木健壮,便于在生产中推广应用.
Abstract
[Objective]To study the asexual reproduction technology in hardwood rooting of walnut.[Method]The 1 to 3 year-old grafted Luhe 1, Xiangling,black and wild walnut seedlings were planted horizontally and the trunks were also buried horizontally with the nutrition medium ,in ad-dition with ABT1(70 mg/kg) and ABT3(70 mg/kg) processed.[Result]When new branches grown with 3 to 4 compound leaves,along the base of new branches ABT1 in concentration of 70 mg/kg was slightly poured for the first time .Two treatments interval for 30 days and they were trea-ted for 3 times total.The new walnut seedlings had the best effect in roots growth with this treatment in this research.[Conclusion]This method of walnut asexual reproduction is simple,low cost and the new seedlings were very strong.In addition this method can be easily applied in produc-tion.
