不同种子处理方法对机插水稻秧苗素质的影响

为探讨培育健壮的机插秧苗的最佳种子处理方法,以期为普及水稻机插秧以及获得高产提供理论依据,于2014年在田间试验条件下研究了不同的种子处理方法(催芽与拌种旱育保姆与否)对机插水稻秧苗素质的影响。结果表明,催芽、拌种旱育保姆的出芽率较其他的处理高,且拌种旱育保姆后,都能显著的增加秧苗的粗度、抑制秧苗生长、增加叶龄,促进根系加粗加快生长的作用显著;催芽处理对秧苗地上部的影响均不显著,却能促进秧苗根的生长,根长显著增加。综合来看,催芽、拌旱育保姆能提高秧苗的素质,是培育机插秧苗的最佳种子处理方法。

Effects of Different Seed Treatment Methods on Seedling Quality ofMechanized Transplanting Rice

The paper aims to ascertain the best seed treatment method of mechanized transplanting rice, and provide a theoretical basis for popularizing of mechanized transplanting rice and achieving high yield. Effects of different seed treatments (germination or dressing Hanyubaomu) on seedling quality of mechanized transplanting rice under the field trial conditions were studied in 2014. The results showed that the sprouting rate of the mechanized transplanting rice seedlings could be appropriately improved under germination conditions and dressing Hanyubaomu, and dressing and dry Hanyubaomu can significantly increase the thickness of the seedlings, inhibited seedling growth, increased leaf years, promoted root bold. Germination treatments were not significant on aerial part of seedling, but it could significantly promote the growth of seedling root and root length. So, germination and mixing Hanyubaomu could improve the quality of seedlings, and was the best way for raising seedlings of mechanized transplanting rice.
