四种紫花首蓿在山东半干旱地区苗期生长的研究

Study on Growth of Four Varieties Alfalfa During Seeding Period in Shandong Semiarid Area

就中牧一号、无棣苜蓿、阿尔冈金及金皇后4种紫花苜蓿在山东半干旱地区的苗期生长进行了研究。结果表明,两种国产苜蓿(中牧一号及无棣苜蓿)出苗率较高,而进口苜蓿(阿尔冈金及金皇后)苗期生长较好。

Four varities of alfalfa were studied in the experiment during seeding period in Shandong semiarid area. The result showed that two varities of native alfalfa germinated well. But during the coming period, two varities of external alfalfa growed well. They had more divarication and lived through the winter better.
