用PP333处理水稻幼苗,可改善秧苗素质,例如秧苗矮壮,假茎宽,叶鞘细胞短宽,叶片增厚,叶肉细胞变大,叶脉增粗,叶绿素含量高,发根力强,抗冷性也有所提高.同时,在密播多肥条件下,经过PP333处理,秧苗仍粗壮,故可节约秧地. Treatment of rice seedlings with PP333 can improve the quality of seedlings, such as seedling short stature, pseudostem width, short and wide leaf sheath cells, leaf thickening, mesophyll cells larger, thicker veins, chlorophyll content, strong hair root, cold resistance Also increased.At the same time, in the close broadcast and more fertilizer conditions, after PP333 treatment, seedling is still sturdy, it can save seedling.
