在大田条件下研究了杂草稻 WR03-12对移栽稻沈农265的产量及稻田环境的影响。结果表明，当栽培田中杂草稻密度超过3株/m2时，移栽稻沈农265的单株穗数、每穗粒数、结实率和千粒重极显著降低，产量极显著下降；移栽稻群体在8：00和16：00时中(80 cm)、下部(40 cm)照度极显著弱于对照，群体透光率降低；日平均气温、白天平均气温和日最高气温极显著降低；群体日平均湿度、白天平均湿度和日最高湿度显著升高。杂草稻密度增大导致栽培稻群体透光率降低，群体湿度加大，稻田群体环境恶化，最终导致减产。

Effects of weedy rice on transplanted rice and paddy environment were investigated in a field experiment with weedy rice WR03-12 and cultivated rice Shennong 265 as materals.It showed that at a weedy rice density over 3 plants per square meter,panicle number per plant,grain number per panice,seed setting rate,1000-grain weight and yield of Shennong 265 significantly decreased.The illuminance in the middle(80 cm)to lower part(40 cm)of the population of Shennong 265 was dramatically weaker than those of control at 8:00 am and 4:00 pm.In addition,the daily average and maximum humidity increased significantly.The rising density of weedy rice led to the decline of population light transmittancand,increase of population humidity in cultivated rice,resulting in the environmental deterioration and the decline of yield.
