【目的]对近年选育的水稻抑草新品种培杂软香、化感稻3号的化感作用进行评价。【方法】将水稻抑草新品种与P1312777进行田间条件下的抑草率比较【结果】培杂软香早、晚李25d抑草率均在45％左右，而化感稻3号和P1312777早季25d抑草率仅为培杂软香的50％左右，表现出较高的不稳定性。[结论】化感稻3号与P1312777化感作用相当；培杂软香化感作用较强．应用价值更高。

[Objective] The aim was to evaluate allelopathy potential of the rice new lines inchuling allelopathic rice 3, Peizaranxiang. [Method] Field experiments were conducted and the rates of inhibiting weeds of rice new lines and Pl312777 were compared. [Resultl The rice new line Peizaranxiang＇s inhibitor rate was the highest both in early season and in later season; the respective inhibitor rates from allelopathic rice 3 and PI312777 only reached about 45% of Peizaranxiang＇s and showed obvious changeful characteristic at the same time [Conclusion] Therefore, the allelolmthic potential between allelolmthie rice 3 and PI312777 was similar： Peizaranxiang was more allelopathie and its application value was higher.
