不同紫花苜蓿品种在佳木斯地区生长及生产特性研究

Growth and Production Characteristics of Different Alfalfa Varieties in Jiamusi

[目的]为了更深入了解不同紫花苜蓿品种在佳木斯地区生长及生产特性,从而更好地研究其在北方地区的抗寒性。[方法]采用随机区组设计方法,在不同生长时期进行产量性状的测定。[结果]播种当年龙牧803植株最高,为66.80 cm;龙牧808单位长度株数、分枝数最高,分别为94株、184分枝,且全区产量最高;各品种在本地区越冬率均为100%;第一茬刈割测定各苜蓿品种产量顺序为龙牧808>龙牧803>驯鹿>敖汉苜蓿>肇东苜蓿>龙牧807;龙牧803种子产量及千粒重最高,比对照肇东苜蓿高20.24 g、0.09 g。[结论]以上所供试的品种在佳木斯地区均具有较高的抗寒性;龙牧803和龙牧808既有较高的产草性能,又具备很好的生产性能。

[Objective] To explore the growth and production characteristics of different alfalfa varieties in Jiamusi and better study their cold resistance.[Method] Using random grouping method to measure yield traits in different growth period.[Results] The result showed that the highest of plant height was Longmu 803 （66.80 cm） ; the highest number of unit length and branch number was Longmu 808,respectively 94 and 184,and Longmu 808 also had the highest yield; the wintering rates of all varieties were 100％ in this area; the yield of first cradle were Longmu 808 ＞ Longmu 80 ＞ reindeer alfalfa ＞ Aohan alfalfa ＞ Zhaodong alfalfa ＞ Longmu 807 ; the highest yield and TKW was Longmu 803,compared with Zhaodong alfalfa higher than 20.24 g and 0.09 g.[Conclusion] The tested alfalfa varieties have higher cold resistance in Jiamusi.Longmu 803 and Longmu 808 have high grass production performance and excellent production performance.
