泡桐种根的贮藏,各地通常用砂藏、室内堆置和露天堆放等方法。哪种方法较好,没有报道过。我们为探索泡桐种根贮藏的适宜方法,对白花泡桐的种根用不同方法贮藏,测定其含水量下降的比例,研究其对种根发芽时间、发芽率和苗木生长的影响。一、材料和方法选用本院苗圃的白花泡桐(Paulownia fortunei)。1978年1月3日苗木出圃后,选取种根90条,按粗、中、细分为三级。粗的直径为1.6—2.6厘米,中的为1.1—1.5厘米,细的为0.5—1.0厘米。每级30条,随机分为三个组合,每个组合包括粗、中、细各10条,在室内经过一周阴干后,分别在室内常温条件下,用
Paulownia root storage, commonly used around the sand, indoor stacking and open storage methods. Which method is better, not reported. In order to explore the suitable storage method for Paulownia species, the root of Paulownia involucrata was stored in different ways and the proportion of water content declining was determined. The effects on the germination time, germination rate and seedling growth were studied. First, the material and methods Select nursery Paulownia Paulownia (Paulownia fortunei). January 3, 1978 nursery stock, select the root of 90 species, according to the rough, medium and fine is divided into three levels. Rough diameter of 1.6-2.6 cm, in the 1.1-1.5 cm, 0.5-1.0 cm for the fine. Each level 30, randomly divided into three combinations, each combination including coarse, medium and thin each 10, after a week in the room after the dry, respectively, at room temperature at room temperature, with
