酸枣仁直播培育枣苗的技术研究

RESEARCH ON REPRODUCTION AND GRAFTING-BREEDING TECHNIQUE OF SOUR JUJUBE KERNELS

用酸枣仁育苗播种出苗率达95%以上,比酸枣核层积处理播种出苗率提高19%,当年地径全部达到嫁接粗度。第2年采用正交设计分别用不同的嫁接时期、接穗处理、嫁接方法对嫁接育苗技术进行研究,结果表明:4月份用蜡封接穗进行劈接效果最佳,成活率高达97 2%,平均苗高156cm,地径1 45cm。

The rate of emergence of seedlings reached over 95% by making use of sour jujube kernels to breed and plant. It increased by 19% in contrast to that of sour jujube pit in the way of stratification and planting. In the same year, the stem diameters of seedlings completely achieved graft thickness.In the second year, the grafting-breeding technique was studied by adopting orthogonal design according to respectively different graft time,scion disposal and grafting. The results revealed that the effect was the best by adopting wax-sealing scion to split and joint in April; the higher survival rate achieved at 972%; the average height of seedlings was 156 cm; the stem diameter of seedlings was 145 cm.
