Data presented as the means with standard deviations were obtained from plants in a randomized complete block design with three replications under natural conditions in Changchun and Jiamusi in 2016. The planting density was 30 cm × 20 cm, with one plant per hill. AYP data were obtained from plants in 10 plots, and the area per plot was 5.76 m ²(2.4 m × 2.4 m)
^*represents significance at p ≤ 0.05 based on Student’s t-tests; ^** represents significance at p ≤ 0.01 based on Student’s t-tests
