| 摘 要： | 目的]探讨在与晚稻套种的情况下,播期对冬榨菜生长的影响。方法]以生产上一般的播期为中心,前后各设2个播种期,共设5个播期,通过试验对照,确定最佳播种时间。结果]8月27日、9月3日和9月24日播种的植株成活率较低,9月10日和9月17日播种的植株成活率较高。播期与冬榨菜的病毒病发生没有直接的联系;对冬榨菜侧芽萌发有显著影响,随播期的延迟,侧芽萌发率逐渐降低,9月10日以后播种,侧芽不再萌发;播期对冬榨菜瘤状茎产量及商品率具有明显的影响,9月10日播种的瘤状茎产量最高。结论]9月10日前后是温州冬榨菜较适宜的播种期。

| Abstract: | Objective] The aim was to investigate the influence of seeding date on the growth of mustard after late-season rice.Methods] Five different seeding date were set based on the normal seeding time;the optimum seeding date was determined by comparisons among them.Results] When sowed on 27 August,3 September and 24 September,few plants survived,while sowed on 10 September and 17 September,a high viability was found.Seeding date showed no correlation with the occurrence of virus,while correlated to the sprouting of lateral buds.The sprouting rate decreased with the sowing time retarded,and no lateral buds spouted when sowed after 10 September.Also,seeding date affected the stem yield and commodity stem rate greatly;highest yield was obtained when sowed on 10 September.Conclusion] 10 September was the optimum seeding date. |
