摘要
目的:研究不同播种期对板蓝根形态学特征、产量及质量的影响,以期为菘蓝适宜播种期的选择提供科学依据。方法:采用大田随机区组试验,调查菘蓝各物候期进程情况,收获时随机采集样品,测定板蓝根形态学指标、小区根产量及活性成分含量,并进行方差及相关性分析。结果:各播种期明显影响菘蓝的物候期进程;播种期与菘蓝根部性状、产量及质量呈负相关;不同播期对板蓝根形态学特征、产量及内在质量形成存在显著差异。结论:安徽阜阳地区菘蓝以3月下旬至4月上旬为适宜播种期;如采用麦药轮作的复种制度,也可将播种期适当延迟至5月下旬至6月上旬。
Objective： To study the effects of sowing date on morphologic characteristics, yield and quality of Radix Isatidis, in order to provide a basis for selection of the suitable sowing date. Method： The experiment was carried out in a randomized complete block design arranged in split plot, the phonological period of Isatis indigotica was investigated and the morphological indexes ,yield and quality at harvest were measured and determined by correlation and variance analysis. Result： The different sowing dates showed a great effect on phonological period of I. indigotica. The biological characteristics,yield and active components of Radix Isatidis were negatively correlated with the sowing date,and the difference of morphological characteristics, yield and active compositions with sowing date was significant. Conclusion： The suitable sowing date of I. indigotica was during the period of time from late March to beginning of the April in Fuyang area, and considering the factors of rational rotation,the time cloud delayed until late May to the beginning of June.
