摘　　要：为了探索核桃嫩枝扦插影响因子,提高生根率,采用L9(3^(4))正交试验方法,开展嫩枝扦插试验研究。结果表明,高湿腐烂是影响核桃扦插是否成功的主要因素,插穗基部采用低浓度高锰酸钾浸泡,并补充吲哚丁酸钾和蔗糖,每天少量喷雾保湿,可以实现核桃嫩枝扦插生根率53.33%。最优方案为:基质采用珍珠岩或蛭石,插穗基部在50 mg/L高锰酸钾浸泡12 h,然后补充0.04%吲哚丁酸钾和1%蔗糖6 h,喷雾间隔时间为6 h喷雾1min。In order to explore the influencing factors of walnut cutting and improve the rooting rate,the experiment of walnut cutting was carried out by L9(3^(4))orthogonal test.The results showed that high moisture rot was the main factor affecting the success of walnut cuttings.The root rate of walnut shoots could be achieved by soaking the base of cuttings with low concentration potassium permanganate and supplemented with indolebutyrate potassium and sucrose.The optimal scheme was as follows:vermiculite or vermiculite was used as the substrate,the base of cuttings was soaked in 50 mg/L potassium permanganate for 12 hours,and then 0.04%potassium indolebutyrate and 1%sucrose were added for 6 hours.The spray interval was 1 minute every 6 hours.
