Abstract
At present ,the cultivation of Jerusalem artichoke is blind with less varieties and the lack of cultivation techniques ,in order to build the reasonable cultivation structure of Jerusalem artichoke ,the yield ,physiological and ecological indexes of two fine artichoke varieties were studied under different density pressure .The results showed that main morphological indexes of artichoke were little impacted by density pressure .Plant height presented a trend of rising ,chlorophyll content presented a trend of decline ,and yield increased firstly and then decreased with the increase of planting density .Suitable planting density differed between two artichoke varie‐ties .Planting distance of 40 cm would be suitable for Qingyu 1 ,which could obtained stronger photosynthetic ability and higher yield .But ,planting distance of 30 cm would be suitable for Qingyu 2 .关键词
