野生酸枣接大枣建园关键技术研究

Key Technology of Building Orchard by Grafting Ziziphus jujuba Mill.on Wild Ziziphus jujuba Mill.var.spinosa(Bunge)Hu ex H.F.Chow

为提高野生枣嫁接大枣建园技术,增加大枣产量和改善品质,开展了坡向、坡位、断根处理、施肥及嫁接保湿方法等对成活率和产量的影响研究。结果表明:地形和坡位对大枣产量有显著影响,阳坡、半阳坡及中坡位更适宜嫁接栽植大枣;枣树断根处理对枣头粗度和平均果质量影响差异不显著,对地径、枣头长、二次枝个数、二次枝长度和单株产量影响差异显著;嫁接后采用封土保湿法比套袋保湿法更有利于提高成活率和生长量。

In order to improve the technique of grafting Ziziphus jujuba Mill.on Wild Ziziphus jujuba Mill.var.spinosa(Bunge)Hu ex H.F.Chow,increase the yield and improve the quality of jujube,the effects of slope aspect,slope position,root-cutting treatment,fertilizing machine grafting moisturizing method,etc.on survival rate&yield have been conducted.Result shows that topography&slope position have significant influences on the yield of Ziziphus jujuba Mill.,and the middle slope position on sun slope and semi-sun slope machine is more suitable for grafting Ziziphus jujuba Mill.;the treatment of jujube root cutting has no difference in the effect on the thickness of jujube head and the average fruit quality.Significantly,there are significant differences in the ground diameter,the length of the date head,the number of secondary branches,the length of the secondary branches,and the yield per plant.After grafting,the terroir moisturizing method is more conducive to improving the survival rate and growth rate than the bagging moisturizing method.
