对从俄罗斯引进的20种箭舌豌豆品种进行了生态引种试验,从生育期、青草产量、植物株高、叶片大小及形状5个主要指标进行了比较研究和统计分析。结果表明:20种俄引箭舌豌豆各品种间的生育期之间相差10 d;编号12品种产量较高,可达到8 065 kg.hm-2,与编号5、6、13、14、17、19的产草量差异显著;编号3、10、12、18与1、4、5、6、7、8、9、11、13、15、16、17、20株高差异显著;俄引箭舌豌豆品种编号12、3、2、18品种在产草量及株高方面好于其它品种,可丰富箭舌豌豆种质资源。
Ecological introduction experiments were conducted on 20 species of arrow-headed peas imported from Russia. Five main indexes including growth period, grass yield, plant height, leaf size and shape were compared and analyzed statistically. The results showed that there was a difference of 10 days between the developmental stages of 20 species of Vitis vinifera L., and the yield of 12 varieties was higher, reaching 8 065 kg · hm-2, , 19 significant differences in the production of grass; No. 3,10,12,18 and 1,4,5,6,7,8,9,11,13,15,16,17,20 significant differences in plant height; Arrow tongue pea varieties 12,3,2,18 varieties in the yield and plant height is better than other varieties, can enrich the arrow tongue pea germplasm resources.
