| 摘 要： | 中薯3号在华北一作区栽培,鲜薯产量从每公顷密度48000株到74070株之间存在显著差异,但从58500株到74070株和48000株到52500株之间差异均不显著,以69450株产量最高;单位面积结薯数从48000株到74070株表现种植密度越大,结薯数越多,差异显著;但58500株到74070株之间差异和48000株到52500株之间均不显著。

| Abstract: | "Zhongshu 3"was planted in the North China. Plant densities ranged from 48 000 to 74 070 plants·hm-2, which had a significant effect on the fresh potato tuber yield. However, there were no significant differences in the tuber yield between the treatments of 48 000 and 52 500 or from 58 500 to 74 070 plants·hm-2. Maximum yield was achieved at 69 450 plants·hm-2. The number of tubers per unit area was significantly increased with increasing plant densities. However, no significant differences were found from 48000 to 58 500 plants·hm-2 or between 69 450 and 74 070 plants·hm-2. |
