- 摘要:
- 运用“最少基本苗”形成的水稻多蘖苗单本植技术, 能充分发挥稻株自身的生长能力, 大幅度延长了稻株的分蘖天数, 使有效分蘖天数增加, 减少了无效分蘖天数, 提高了“蘖穗调节率” , 是一个高分蘖力, 高成穗率, 高蘖穗率的高产群体, 在抽穗期使与伸长节相关的绿叶数持续时间长, 粒叶比、有效叶面积率和高效叶面积率得以提高, 延长了群体叶面积功能期, 形成了一个高光效群体, 提高了后期群体的光合生产能力而高产。
- Abstract:
- The technique of single -plant t ransplantation could fully bring rice plant g rowing capacityinto play , greatly ex tend tillering duration , increase effective tillering day s and decrease invalid tilleringday s .It makes three -high population (high t illering ability , high heading rate and hig h tiller -head ratio).At heading stage , the technique could prolong the duration of green leaves , increasespikelet leaf area ratio , effective leaf area rate and hig h effective leaf area rate and form a hig h photosynthetic efficiency population .Therefore , productive abili ty during grain filling stage w as increased .
