摘要
紫花苜蓿在新垦区第一次播种时,自然结瘤率不高,固氮效率低。接种优良的苜蓿根瘤菌能增加根瘤及固氮量和产量。
Natural nodulation and nitrogen fixation of Medicago sativa in newly cultivated area was poor.Proper In- oculation with Rhizobium melilvti was essential both in nodulation and nitrogen fixation to obtain a notable higher harvest in alfalfa production.
