与插秧栽培相比，塑盘抛秧栽培群体于物日增量以中期最高，根、茎、叶、穗同时增加，增多部份分配给叶高于茎，但叶片变薄、比叶重下降；增产的主要原因是增加了第二次分蘖穗和齐穗后茎叶累积的同化物向谷粒运转较多；增产潜力源于有效蘖干物库容量、叶片总光合同化产物源和同化物运转流量等的增加以及栽培技术效应等。 Compared with transplanting seedling, plastic discaiing transplanting seedlings increased daily in medium and highest in the mid-term. Roots, stems, leaves and spikes increased at the same time, and increased part of leaves were distributed to the leaves higher than the stems, but the leaves became thinner and the specific leaf weight decreased . The main reason for increasing yield was that the assimilates accumulated in the stems and leaves of the second tillering panicle and the heading panicle moved more to the grain; the potential for increasing yield was due to the effective tillering dry matter pool capacity and the total photosynthetic assimilation product source and assimilate movement Flow rate increase and cultivation techniques and so on.
