摘要
以右玉县为试点，于2011—2012年研究了7个不同定植时间对芦笋缓苗期、冬前农艺性状、越冬出苗情况的影响。结果表明，6月11日到7月1Et定植，芦笋越冬成活率可达97％-98％，是冷凉沙化区芦笋定植的适宜时间；定植时间与冬前生育指数和越冬成活率呈显著负相关，定植时间通过影响芦笋的冬前生育指数而影响芦笋越冬成活率。
The effect of seven different replanting time on revival period, agronomic traits before winter, emergence situation after overwinter were analyzed in Youyu county in 2011-2012. The results showed that, survival rate of over winter is 97%-98% when aspara- gus was replanted from June 1 lth to July 1st, which is the optimal replanting period in cold desertifiod areas. The replanting time is nega- tively correlated with the survival rate of over winter of asparagus significantly. The replanting time effects survival rate of asparagus through fertility index before winter.
