摘　　要：室内试验和田间试验结果表明,水稻种子萌发不会影响杂草稻种子萌发。水稻与杂草稻不同比例田间试验结果表明,水稻与杂草稻基本苗在27∶1～320∶1时,水稻不影响杂草稻的生长,对杂草稻分蘖数、株高和杂草稻产种量影响不显著。Laboratory experiment and field trial showed that germination of rice seeds had no suppressing effect on seeds germination of weedy rice. Field trial concerning plant growth density with different ratio of rice and weedy rice showed that when plant density ratio of rice and weedy rice got to 27 ： 1 - 320 ： 1, the rice had no suppressing effect on weedy rice growth,particularly no significant influence on tiller number,plant height and seeds yield of weedy rice.
