红枣有极高的营养、保健与药用价值,近年来倍受世人青睐。但因苗木难繁而严重制约了枣树的栽培与发展。常规繁育方法是靠母树根蘖或归圃育苗,酸枣为砧木嫁接,但周期长,资源少,成本高。近年来所采用的组培法,扦插法也因技术高,要求严,投资大,练苗难而难以普及。现介绍一种利用枣树苗圃掘苗后残根萌蘖育苗方法。其特点是周期短,费工少,效益好;缺点是管理不细时,苗高差异大。1、圃地选择与改良圃地应为地势平坦、避风向阳、通透性好的沙壤地。若土壤过粘应用腐殖质土与沙土掺翻改良。2、整地(1)将准备第二年春季出圃的成品苗圃地,于头一年10月中、下旬在行间施优质农家肥2—3吨/亩,以开深30厘米沟施入为好,也可直接翻施,施肥后灌
Jujube has a very high nutritional value, health care and medicinal value, much favored by the world in recent years. However, due to difficult seedlings and seriously restrict the jujube cultivation and development. Conventional breeding methods rely on parent tree tillers or nursery nursery, jujube grafted rootstock, but long cycle, less resources, high cost. In recent years, the tissue culture method, cutting method is also due to high technology, strict requirements, large investment, difficult to popularize difficult to popularize. Now introduce a jujube seedling nursery after digging seedling sprouting nursery method. Its characteristics are short cycle, less labor, good efficiency; disadvantage is that management is not fine, the difference in height. 1, garden selection and improvement of nursery should be flat, sheltered from the sun, good permeability of the sandy soil. If the soil is too viscous use of humus soil mixed with sand mixed improvement. 2, site preparation (1) will be prepared for the second year in spring nursery finished nursery, in the first year in mid-October, late in the line of high-quality farmyard 2-3 tons / mu, to open deep 30 cm ditch into Well, but also directly turn Shi, fertilization after irrigation
