| 摘 要： | 在海拔2530 m的南方冷凉山区退耕地上对18个牧草品种进行了引种试验。通过对各牧草的物候期、绝对生长率、相对生长率、茎叶比、产草量、青干比、净同化率等生产性状和经济指标的分析表明:18个牧草品种中15个品种能在冷凉山区正常生长,其中多年生黑麦草(马达)、多花黑麦草(旺饲)、紫花苜蓿(WL-612)和紫花苜蓿(四季旺)、白三叶(海法)各性状表现优良,可作为冷凉山区退耕还草的推广草种(品种)。

| Abstract: | Eighteen pasture grass varieties were tested in the cold mountainous region with the altitude of 2,530 meters. The tests were focused on production characters and economic iudex, induding growth rate, stem\leaf tatio, forage yield, damp\dry grass ratio and net assimilation rate. The results showed fifteen of them can grow normally in this region, especially pernnial ryegrass, Itlian ryegrass, alfalfa (WL-612) alfalfa (Siriver) and white clover (Haifa). The five varieties were suggested to plant widely in the region. |
