By combing documentation and the work, applications of crop chemical control techniques on corn production in China have extensive theoretical and experimental basis with prominent effects. Currently the application is more in corn anti-lodging, and in other fields is still less, mainly due to little efforts to promote and low input-output. Strengthening policy-guiding, administrative monitoring, fund and technical support, ensuring accurate and effective use of chemical control technique can produce superior agricultural products, which is beneficial for farmers.%通过对可查文献资料的梳理,结合日常工作,提出目前作物化学控制技术在玉米生产上的应用已经具备较广泛的理论和试验基础,且效果比较突出.目前应用较多的领域主要是玉米防倒伏,在其他领域的推广应用仍然较少.主要原因是推广力度小,投入产出比较低.提出政府应加大扶持力度,加强政策引导和资金支持,同时要强化行政监管和技术支持,确保正确、有效地使用化学控制技术,生产优质农产品,使农民尽早受益.
