摘要
酸枣俗称刺枣、棘,为灌木或小乔木,耐干旱、瘠薄和盐碱,适应性强,可作为嫁接大枣的砧木,在我国华北地区分布较广。枣树原产我国,是重要的经济林树种,适应性强,寿命长,效益高。过去因嫁接方法不当,成活率较低,因此发展缓慢,成效不高,经过课题组人员不断实践,总结出一套快捷可靠利用野生酸枣嫁接大枣的嫁接技术,生长十分迅速,而且成活率高,见效快,经实验,7年生枣树株产6.4kg,每公顷达到26320kg的高产,扣除各种费用,每公顷纯收入为14380元,达到了丰产、优质、高效的目标。
jujube jujube,commonly known as prickly spines,is a shrub or small tree,drought resistance,barren and saline alkali,strong adaptability,can be used as the rootstock grafted jujube,in North China has a wide distribution.Jujube originated from China,is the economic,forest tree is an important and strong adaptability,long service life,high efficiency.In the past because of improper methods of grafting,survival rate is low,so the slow development,efficiency is not high,the research group practice,summed up a set of fast and reliable use of wild jujube grafted jujube grafting techniques,growth is very rapid,and high survival rate,fast effect,after the experiment,jujube strain producing 6.4kg for seven years students,up to 26320 kilograms per hectare yield,deducting the various costs,the net income per hectare is 14380yuan,to reach a high yield,high quality,efficient target.
