Lee D R等研究抗草甘膦大豆对抗草甘膦棉花的影响发现:大豆对棉株收获高度无影响,但对棉花单产有影响。在棉行间大豆株距1m、全生育期干扰的情况下,棉花单产减少14%。而在棉行间大豆株距0.19m仅干扰1周时,棉花减产0.4%～1.0%;干扰持续2周、4周、6周时,棉花分别减产1%～3%、5%～ Lee D R et al. Studied the effects of glyphosate resistant glyphosate resistant glyphosate-resistant cotton. Soybean showed no effect on cotton boll height but affected cotton yield. In the cotton line between the soybean plant spacing 1m, the whole growth period of interference, the cotton yield reduced by 14%. While the cotton yield reduced 0.4% -1.0% when the spacing of soybean plant was only 0.19m in the cotton line for one week. The cotton yield decreased 1% -3%, 5% ~ 6%
