国内外10种紫花苜蓿引种试验研究

Introducing research on ten alfalfa varieties home and abroad

研究了国内外10个紫花苜蓿品种在我国河南省种植的主要生产性能及适应性。结果表明,国外苜蓿品种种子质量较高,在我国河南地区普遍生长良好,均能安全越冬,生产性能一般优于我国地方品种。在10个苜蓿品种中,78,MHA1和78-1的年鲜草产量较高,分别为93365.6,89837.2和87770.4kg/hm2;78,赛特和MHA1的年干物质产量较高,分别为18309.0,18049.2和16799.6kg/hm2;赛特,78,MHA1和78-1的年蛋白质产量较高,分别为4163.7,3919.1,3593.5和3568.7kg/hm2。这些品种能够满足不同生产目的的需要,可以在我国河南地区推广种植。研究还发现,各品种的茎叶比、年干物质产量、年蛋白质产量等主要生产性能指标之间呈高度正相关。

The performance and adaptability of 10 alfalfa varieties home and abroad are studied in Henan region.The results show that foreign alfalfa varieties are better in seed quality,generally grow well in Henan province,can all live through the winter and show better performance than domestic varieties.Among the 10 varieties studied,78,MHA1 and 78-1 are the best varieties in annual fresh grass yield,individually to be 93 365.6,89 837.2 and 87 770.4 kg/hm^2;78,Sitel and MHA1 in annual DM yield,to be (18 309.0),18 049.2 and 16 799.6 kg/hm^2 separately;Sitel,78,MHA1 and 78-1 in annual crude protein yield,to be (4 163.7),3 919.1,3 593.5 and 3 568.7 kg/hm^2 individually.These alfalfa varieties can meet different production purposes and deserve extension in Henan province.The research also shows that the main performance indices of alfalfa variety are highly correlated with each other,which may be helpful in alfalfa breeding.
