北五味子(Schisandra chinensis Baill.)系天然分布于我国东北、朝鲜和俄罗斯远东地区的重要药用植物资源。1992年以来,我们针对自然资源日益减少,市场需求不断增加的状况,系统地开展了由野生变家植的研究,获得3年生园平均亩产浆果113.3kg,4年生园466.2kg,5年生园596.9kg的丰产高产记录。为促进北五味子栽培这一新兴产业的发展,现将丰产栽培技术要点介绍如下:1 园地的选择和苗木栽植1.1 园地选择 北五味子适于微酸性及酸性土壤,在无霜期115天以上,≥10℃年活动积温2300℃以上的区域可大面积栽培。建立北五味子园应选择排水好、地下水位低的平地或背阴坡地,篱架栽培,株行距0.75～1.0×2m。1.2 定植前的准备 入冬前按确定的行距挖深50～
Schisandra chinensis Baill. Is a kind of important medicinal plant resource that is naturally distributed in northeastern China, North Korea and Russia’s Far East. Since 1992, in response to the declining natural resources and increasing market demand, we systematically conducted research on wild plantations and obtained an average yield of 113.3kg per mu in 3-year-olds, 466.2kg in 4-year-olds, and 5-year-olds 596.9kg of high yield and high yield records. To promote the development of this new industry of Schisandra cultivation, the main points of the high yield cultivation techniques are as follows: 1 Selection of field and planting of seedlings 1.1 Selection of field Schisandra chinensis is suitable for slightly acidic and acidic soils, with a frost-free period of more than 115 days and a temperature of ≥10 ℃ Annual activity accumulated temperature above 2300 ℃ area can be large-scale cultivation. The establishment of the North Schisandra should choose a good drainage, low groundwater level or shady slope, fence cultivation, spacing of 0.75 ~ 1.0 × 2m. 1.2 Preparation before planting Determine the depth of the line before the winter dug 50 ~
