晋南苜蓿已有近2,000年的栽培历史,目前面积64.8万亩,约占全省苜蓿面积的60%。1982—1983年我们对晋南苜蓿植物学特征和生物学特性进行了试验。一、试验材料来自运城、临猗、永济等县,系同一品种,称为晋南苜蓿。这些县所处的纬度为北纬34°40′至35°40′;降雨量年平均479.4—550毫米。种子采收于1981年,千粒重1.70—2.40克,发芽率97—99%。
Jinnan alfalfa has nearly 2,000 years of cultivation history, the current area of 648,000 mu, accounting for about 60% of the province’s alfalfa area. In 1982-1983 we tested the botanical characteristics and biological characteristics of alfalfa in Jinnan. First, the test materials from Yuncheng, Linqu, Yongji and other counties, the same species, known as Jinnan alfalfa. The latitude of these counties is between 34 ° 40 ’and 35 ° 40’ north latitude; mean annual rainfall is 479.4-550 millimeters. Seeds were harvested in 1981, grain weight 1.70-2.40 grams, the germination rate of 97-99%.
