玉米前茬对5种中药材生长及产量的影响

Effects of corn stubble on growth and yield of 5 kinds of traditional Chinese medicine herbs

采用田间试验和统计分析的方法,以重茬为对照,探索玉米前茬倒茬对陇西5种中药材出苗率、生长量、生育期以及根腐病等影响。结果显示,玉米前茬倒茬对5种中药材的出苗率、生长量、产量以及根腐病都有不同程度的影响,而对生育期影响不大。结果表明,轮作倒茬是中药材稳定增产的有效措施,玉米茬种植黄芪、关防风、红芪,具有较显著的增产增收效果。

Based on continuous planting to explore the effects of corn stubble on 5 kinds of traditional Chinese medicine herbs about seedling emergence,growth,maturation and root rot by field test and statistical analysis. The previous corn and rotation had different effects on the seedling emergence rate,growth,yield and root rot of the 5 kinds of traditional Chinese medicine herbs,but had no effect on developmental phase. The results showed that the corn rotation was an effective measure for the stable production of traditional Chinese medicine herbs,and the corn stubble was cultivated with Radix Astragali,Radix Ledebouriellae and Radix Hedysari,which had a significant influence on yield increase and benifit increase.
