以汕优６３为材料，研究了不同育秧环境下秧苗生理和形态结构方面的差异及对本田生长的影响。旱育秧苗植株矮壮，体内积累的淀粉多，过氧化氢酶活性强，叶绿素含量高，抛植大田后发根快、分蘖多，具有明显的“爆发”优势，最终成穗率高，有效穗多，产量较高；湿润育秧的秧苗，秧田期生长量大，体内积累的淀粉少，抛植大田后发苗慢，缓苗期长，最终有效穗少，产量较低；前期旱育后期多雨寡照的秧苗体内积累的淀粉量及过氧化氢酶活性等均不及正常旱育秧，抛植大田后秧苗体的“爆发”优势丧失，产量与湿润育秧相仿
Using Shanyou 63 as material, the differences of physiological and morphological structure of seedlings and their effects on Honda growth under different seedling raising were studied. The plantlets of drought-tolerant seedlings are short and strong, with more starch accumulated in the body, more catalase activity and higher chlorophyll content. After transplanted in the field, rooting and tillering are more and have obvious advantages of “burst” Spikes and high yield; wet seedling seedling, seedling growth period, the accumulation of starch in the body less, throwing the field after the hair seedling slow, slow seedling period, the final effective spike less, the yield is low; pre-drought period Rain and oligo seedlings accumulated in the body of starch and catalase activity and other activities are less than the normal dry seedlings, throwing the field seedlings after the “outbreak” lose the advantage of the same yield and moist seedlings
