Abstract
The growth character of weedy rice in mixture transplanting with different morphological type rice varieties were studied.Compared with Shennong 265 with erect panicle type,tiller of average ability,Liaoyan 16 with the plant morphological type of curved panicle,tiller of stronger,great-canopy reduced the plant height,1eaf area,plant dry weight,the number of tillers of weedy rice significantly in the transplanted rice.The number of rice panicles,1eaf area index and dry matter weight of Shennong 265 were decrease seriously under weedy rice interferenee of 12 plants per square meter,which can result the yield of rice decline.However,the yield components of Liaoyan 16 was no decrease markerly.The competition of Liaoyan 16 between two plant morphology rice varieties was more powerful compared with the Shennong 265.It will be important in the agricultural program of control weedy rice.
