由于建立松树无性系种子园工作的进展,培育嫁接苗的问题占重要的地位。试验表明,在温室内培育嫁接苗有很大的优越性。为确定欧州松嫁接的好方法,1977—1980年期间在克拉夫基耶夫林管区,斯达洛—彼得洛夫森林经营所曾做过一系列试验,用金属骨架的拱形温室,总面积900平方米,从3月末到6月用聚乙烯薄膜覆盖,苗木生长期间温室空气湿度变动幅度为80—100％,热天温度可升高到39℃,冷天较空地高4—5℃。为了保持较高的相对湿度,热天应进行两次有效的灌溉(早晨和晚上),使用“杜马”型灌溉系统。由通风窗进行通风。
Due to the progress of establishing the clonal seed orchard of pine trees, the problem of cultivating the grafted seedlings occupies an important position. Experiments show that in the greenhouse cultivation of grafted seedlings have great advantages. In order to establish a good method for grafting Pinus sylvestris, a series of experiments were conducted during the period 1977-1980 at the Vladimirovin Forest District and the Stalow-Petrov Forest Management Office. A metal greenhouse arched greenhouse with a total area 900 square meters, covered with polyethylene film from the end of March to June, greenhouse air humidity during seedling growth range of 80-100%, hot days temperature can be increased to 39 ℃, cold days higher than open space 4-5 ℃. In order to maintain a high relative humidity, hot days should be two effective irrigation (morning and evening), the use of “Duma” type irrigation system. Ventilate through louver.
