北票地区酸枣嫁接金丝王大枣高效育苗试验

通过进行酸枣嫁接金丝王大枣苗试验研究,结果表明,不同的嫁接方法、不同嫁接时期影响到嫁接苗的成活率,不同的施肥配方均影响到苗木新梢生长量;春季4月24日左右采用插皮接较之其他嫁接方法能显著提高嫁接苗成活率;采用氮、磷和硫基钾其三元素配比为2∶1∶1养分配比能明显提高新梢生长量,与其他配比有极显著差异,当年新梢生长达到了58.3cm。

Efficient Breeding of Zizyphus jujube Grafting with Jinsiwang Chinese Date in Beipiao Area

Experiment of Zizyphus jujuba grafting with Jinsiwang Chinese date were conducted.Result shows that: different grafting methods and different grafting periods will influence the survival rate of grafting seedlings;different fertilization formulations are all influence the seedling shoot growth;bark grafting method can significantly increase the survival rate of grafted seedlings on April 24 in Spring;nutrient ratio of nitrogen:phosphorus:sulfur radicals(2:1:1),which can improve the growth of new shoot,have significant differences with other ratios;shoot growth in the first year reach 58.3 cm.
