本文主要介绍西班牙、意大利(主要是西西里岛) 和希腊等国少雨地区(年降雨量介于200～600毫米之间,一般干旱地区的年雨量不足300毫米) 一些苗圃的育苗技术。苗圃土壤:实践证明,任何排水良好、松脆和肥沃的土壤都可以育苗。由于育苗树种多为松树和桉树,它们都不很耐碱,因此一般不用钙土作苗床。在西班牙的加达马苗圃,在混合土壤(把各种土壤混合起来,其中含有一部分粘土) 中再加入等量的砂子来进行育苗。在西班牙的海谷尔那苗圃中,育苗用的土壤由75%的森林腐殖质(酸碱度为6) 和25%的有机肥合成。而在罗达、其加2个苗圃中,一般在泥炭土中再加入各0.15%的N、P、K。在希腊的亚里阿 This article focuses on nursery techniques in nurseries in sparsely populated areas of Spain, Italy (mainly Sicily) and Greece, with annual rainfall of between 200 and 600 mm and annual rainfall of less than 300 mm in general arid regions. Nursery soil: It has been proven that any well-drained, crisp and fertile soil can be nursed. As seedlings are mostly pine and eucalyptus trees, they are not very alkali-resistant, so generally do not use calcium for seedbed. At Spain’s Cedar Nursery, seedlings are nurtured by adding the same amount of sand to the mixed soils (a mixture of soils containing a portion of the clay). In the Sea Guerna Nursery in Spain, the nursery soil is made up of 75% forest humus (pH 6) and 25% organic fertilizer. And in Roda, plus 2 nurseries, it is common to add 0.15% N, P, K in peat soil.
