不同嫁接方式对淇县无核枣嫁接苗成活率及嫁接效应的影响

Effect of Different Grafting Methods on Survival Percent of Grafted Seedlings and Grafting Effect of Qi Country Seedless Jujube

研究了嫁接时期、方法、接穗药剂处理等对淇县无核枣嫁接成活率及嫁接效应的影响。结果表明,不同嫁接方法以切接法效果最好,成活率达70%;从4月上旬至中旬适当推迟嫁接更有助于接穗成活;提前削接穗并用湿毛巾包裹处理比在苗圃现削现接,嫁接成活率提高40个百分点,新梢生长量提高101.6%;接穗封蜡、接后套袋处理比常规劈接的成活率分别提高33个百分点和17个百分点;用维生素C浸泡接穗的成活率,比常规劈接提高13个百分点;IBA 100 mg/L处理的接穗成活率、新梢生长量分别比常规劈接提高27个百分点、216.7%,其次为NAA。

Effects of the different grafting methods and scions treatment with chemical reagents on survival percents of the grafting seedlings and grafting effect of Qi Country seedless jujube were studied in this paper.The results showed that the effect of cut-grafting technique was the best in different grafting methods and the survival rate was 70%.Adequate extension of grafting period was more helpful for survival of scions from early April to mid April.Advance of preparing scions and wrapping them in wet towels could greatly increased the survival percents of the grafting seedlings by 40 percentage points and improving work efficiency compared with the traditional grafting way,at the same time,the increment of new shoots increased by 101.6%.The survival percents of grafting seedlings increased by 33 percentage points and 17 percentage points respectively by sealing wax and bagging after grafting for scions.The survival percent of grafting seedlings of scions soaked in Vc increased by 13 percentage points compared with common grafting.The survival percent of grafting seedlings of scions soaked in IBA was higher than that of common grafting,increased by 27 percentage points,followed by NAA,increased by 13 percentage points.The survival percent of grafting seedlings of scions treated with IBA was higher than that of common grafting,increased by 216.7%.
