在科学实验活动中,我们观察到杜仲在土壤湿润,温度适宜(平均相对湿度在75%左右,气温16—20℃)的条件下,都能萌芽发根。在生产实践中,杜仲的无性繁殖有以下几种方法: 一、扦插法: 1.苗圃的选择:杜仲扦插的苗圃地,应以荫凉、湿润、腐殖质较多的沙壤土为好。2.整地;苗圃地要深挖,施足有机肥料如猪栏粪、鸡屎粪以及腐殖质等作基肥,然后视地形做畦2.5—3尺宽、高5寸,上面成龟背形的苗床。3.扦插季节和方法:在早春新叶未萌发前,
In scientific experiments, we observed that Eucommia sprouted roots when soil was moist and the temperature was suitable (the average relative humidity was about 75% and the temperature was 16-20 ℃). In practice, Eucommia asexual propagation in the following ways: First, cutting method: 1. Nursery choice: Eucommia cuttage nursery should be shady, moist, humus more sandy loam as well. 2. Land preparation; Nursery to dig deep, Shi enough organic fertilizer such as pig’s pen manure, chicken feces and humus as basal fertilizer, and then depending on the terrain to do 畦 2.5-3 feet wide and 5 inches high, . 3. Cuttings season and method: new leaves in early spring before germination,
