不同生态种植模式对延胡索生长性状及产量的影响

Effects of Different Ecological Planting Patterns on Growth Traits and Yields of Corydalis yanhusuo

探讨了不同生态种植模式对延胡索生长性状及产量的影响,以延胡索单作为对照,通过测定延胡索株高、叶面积、地上鲜重、地下茎数、地下块茎数量、地下鲜重、产量等指标,研究、分析不同生态种植模式对延胡索生长性状及产量的影响。结果表明:不同生态种植模式下延胡索的生长状况、产量均有所差异,根据地上部分性状-株高;地下部分性状-地下鲜重、地下块茎数;各小区鲜产由高至低的生态种植模式为延胡索与水稻水旱连作模式(Z3)>猕猴桃林下种植延胡索模式(Z1)>延胡索单作模式(CK)>柑橘林下间作延胡索模式(Z2)。相关性分析表明:延胡索叶面积与地上鲜重、地下茎数显著正相关;地下块茎数与株高、叶面积、地下鲜重、地下茎数显著正相关;产量与株高、地下鲜重、地下块茎数显著正相关。主成分分析表明:地上部分株高以及地下部分的地下块茎数、地下鲜重、地下茎数可以作为反映延胡索生长性状的主要指标。以期为延胡索“南药北移”、规模化推广生态种植技术提供理论依据和技术支撑。

This study investigated the effects of different ecological planting patterns on the growth traits and yield of Corydalis yanhusuo.Using monoculture of Corydalis yanhusuo as a control,the study measured different indicators including plant height,leaf area,above-ground fresh weight,number of underground stems,number of underground tubers,underground fresh weight,and yield.The results showed that different ecological planting patterns have influenced the growth conditions and yield of Corydalis yanhusuo.Based on the above-ground traits(plant height)and underground traits(underground fresh weight,number of underground tubers),the ecological planting patterns ranked from highest to lowest fresh yield were as follows:Corydalis yanhusuo in rice rotation(Z3)>Corydalis yanhusuo planted under kiwifruit trees(Z1)>Monoculture of Corydalis yanhusuo(CK)>Corydalis yanhusuo intercropped under citrus trees(Z2).Correlation analysis indicated significant positive correlations between leaf area of Corydalis yanhusuo and above-ground fresh weight,number of underground tubers;number of underground tubers and plant height,leaf area,underground fresh weight,number of underground tubers;and yield and plant height,underground fresh weight,number of underground tubers.Principal component analysis showed that plant height for above-ground traits,and number of underground tubers,underground fresh weight,and number of underground tubers for underground traits can serve as major indicators reflecting the growth characteristics of Corydalis yanhusuo.This study aims to provide a theoretical basis and technical support for the"Southern Medicine Moving North"strategy of Corydalis yanhusuo and the large-scale extension of ecological planting technologies.
