摘要: 在马铃薯的块茎增长期亩施20克多效唑(有效成分),可使叶片叶绿素含量增加22.8%,净光合强度提高56.7%,还能抑制地上部的营养生长,促进光合产物向块茎分配,使经济系数提高66.7%,大薯块显著增多,从而提高了产量和商品性.

关键词: 多效唑, 马铃薯

Abstract: During potato tuber enlargement stage applying paclobutrazol (effective constituent 20 g/mu),can inerease the chlorophyl content by 22.8,net photosynthetic intensity by 56.700,inhibit vegetative growth of the parts above ground, promot distribution of photosynthate to potato tuber.Economic efficiency increased by 66.7%,the percentage of larger-size tuber increased remarkably,as a result, potato yield and commercial value both higher.

Key words: Paclobutrazol, Potato
