- 摘要:
- 在前期资源调查、引种的基础上，对已筛选出的在青海地区观赏性高、抗性强的金露梅、银露梅、红花岩黄芪、砂地柏4种野生地被植物品种在青海省江河源区、环青海湖区、柴达木盆地区，东部黄土丘陵区进行区域试验，以期确定4个品种的。结果表明：4种地被植物在5个区域内生长均表现良好。其生长量与海拔高度基本呈负相关，与年积温呈正相关。即海拔越高，年积温越低，年生长量越小；海拔越低，年积温越高，年生长量越大。在海拔低于3 740 km、年均温大于0.7℃，≥10℃积温不低于103.86℃的地区均能正常生长，并能体现其观赏性。
- Abstract:
- Based on the resource investigation and introduction in the early stage, the regional test of 4 wild cover plants of Potentilla fruticosa L., Potentilla glabra Lodd., Hedrysarum multijugum and Sabina vulgar screened in 4 different regions in Qinghai area with high ornamental function and strong resistance were done, in order to accurate positioning of these 4 varieties. The results showed that 4 species of ground cover plants in 5 regions performanced good. The growth rate were negatively correlated with altitude, annual accumulated temperature was positively correlated with. The higher altitudes, annual accumulated temperature was lower, the annual growth of more small; the lower the altitude, annual accumulated temperature was higher, the greater the amount of annual growth. At an altitude of less than 3 740 km, the mean annual temperature was higher than 0.7℃, ≥10℃ accumulated temperature of not lower than 103.86℃ in the normal growth, and its ornamental was reflected.
