为了解决当前宁夏南部山区紫花苜蓿品种少、产量低、品质差等问题,促进苜蓿产业健康发展,试验对引进的国内外11个优质高产苜蓿品种的生物学性状(株高、枝条数、干鲜比、茎叶比、鲜草产量、干草产量等)进行测定比较。结果表明:国外苜蓿品种的生物学性状优于国内品种,4010和皇后的干草产量分别比对照提高38.30%、33.99%,不但产量高,而且适应性好。
In order to solve the problems of less species, low yield and poor quality of alfalfa in the mountainous area of southern Ningxia, and to promote the healthy development of alfalfa industry, the biological characteristics of 11 high and high yield alfalfa varieties (plant height, number of branches, fresh and dry Ratio, stem-leaf ratio, fresh grass yield, hay yield, etc.) were measured and compared. The results showed that the biological characters of foreign alfalfa varieties were better than those of domestic varieties, and the hay yield of 4010 and Queen increased by 38.30% and 33.99% respectively compared with the control, which not only had high yield but also good adaptability.
