枣树育苗方法很多,生产中常用的有下面两种, 一、嫁接育苗 此种方法能充分利用酸枣资源,在较短的时间内培育大量优良品种苗木。 1.砧木的培育:将充分成熟的酸枣果实,加水搓洗,蜕皮浮核。于11～12月沙埋层积处理,层积时间不少于80天。翌年4月进行选芽分期播种,以提高出苗率。播种方 式采用双行密播,大行距70匣米,小行距30匣米,穴距15匣米,每亩用种核10～12斤。为了保证出苗率,每穴播种两三粒,种上覆土不宜超过2厘米厚。幼苗出土后加强肥水管理,当年苗高可达60厘米,播种第二年就可嫁接。 2.嫁接方法 ①劈接:嫁接时间以春季砧木发芽前15～20天为宜。将砧木近地面光滑处剪断,削平剪口,从剪口断面中间用刀下劈4～5厘米长的 Jujube seedling many ways, the production of the following two commonly used, one, grafting seedlings this method can make full use of jujube resources, in a short period of time to cultivate a large number of fine varieties of seedlings. 1. Rootstock cultivation: the full ripe jujube fruit, water scrub, molt floating nuclei. In 11 ~ December sand buried layer processing, stratification time of not less than 80 days. The following year in April to carry out selective budding sowing, in order to improve the emergence rate. Sowing ways using double-line sowing, Dali line from 70 boxes of rice, small row of 30 boxes meters, hole spacing 15 box meters, with seed per acre 10 to 12 pounds. In order to ensure the emergence rate, sowing two or three tablets per hole, the overlying soil should not exceed 2 cm thick. After the excavated seedlings strengthen fertilizer and water management, when the seedling height of up to 60 cm, sowing the second year can be grafted. 2 grafting method ① cleavage: grafting time to spring rootstock 15 to 20 days before germination is appropriate. The rootstock near the ground smooth cut, flat cut, cut from the middle of the section with a knife split 4 to 5 cm long
