摘要
研究表明,水稻小苗(叶龄3～4)、中苗(叶龄5～8)有土拋秧均比无土抛秧利于生长和增产,尤其小苗更是如此。大苗(叶龄9～10)有土抛秧前期生育优于无土者,至中、后期二者间差异甚微,但无土抛秧必须以多蘖壮秧为前提。
It was showed in this study that the growth and the yield increase of scattering-seedling rice with soil was superior to that without soil for young seedling (3～4 leaf age) and middle seedling (5～8 leaf age), especially for the young seedling. For the large seedling, there was some advantageous in scattering seedling rice with soil only at early stage and this should be based on the strong sprout with many tillers.
