摘要
对4个紫云英品种(系)生长发育过程的特征特性进行研究。结果表明,福建省农业科学院土壤肥料研究所选育的新品系闽紫6号和84471031表现中熟;在福建省闽侯地区生长良好,株高、茎粗、分株数等性状均优于余江大叶和宁波大桥2个品种,盛花期鲜草产量分别达37190 kg/hm2和d 39944 kg/hm2;参试品种(系)的生物量和N、P、K养分积累量的大小均为:84471031>闽紫6号>宁波大桥>余江大叶。
We investigated phenophase and main economic character of 4 strains of breed and varieties. Results indicate that two varieties （ Minzi No. 6 and 84471031 ）, which were bred by Institute of Soil and Fertilizer, Fujian Academy of Agricul- tural Sciences and expanding propagation now, performed middle - maturity and great growing characteristics in Minhou County of Fujian Province, and theirs biomass were 37190 kg/hm2 and 39944 kg/hm2 , and theirs Main Economic Character were better than that of Yujiangdaye and Ningbodaqiao. The order of biomass and accumulation of nutrients absorbed were 84471031 〉 Minzi No. 6 〉 Ningbodaqiao 〉 Yujiangdaye.
