| Abstract: | Effects of planting seedlings and row--spacing, hill--distance on growth and yield was studies by using of L8（4 ×2^4 ） orthogonal experimental design. The results showed that the best planting seedlings was 120000/667m2, the yield was highest, it＇s 623. 7kg/667m2, planting seedlings was 120000/667m2, the yield was lowest, it＇s 559. 1kg/667m2. Yield of row--spacing at 25cm was higher than row--spacing at 28. 57cm by 46. 9kg/667m2, the difference reached significantly level. |
