The results indicated，the comprehensive traits of Guihuai 2，Guihuai 6 were so good that they were high or rich yield and wide suitable. The yield of building-rack culture was significantly higher than that of no building-rack culture，while the economic benefits of building-rack culture was no more well than no building-rack culture’s. So it was thought that the cultivars of Guihuai 2，Guihuai 6 could be broadcasted and used widely，but different culture technologies were respectively used for them，which both of them could be developed economic benefits to the full.
