1. Eight varieties of field design were tested with an average row spacing of 0.38m and a spacing of 0.105m and 6 rows. The area of each cultivar was 666.7m ~ 2 and the density was 250,600 plants / hm ~ 2. The net area of the experiment was 0.53hm ~ 2 . The first frost period: October 10, the final frost period: March 23, frost-free period 200d.
