摘要
田间草害是导致玉米产量和品质下降的主要因素之一,为进一步了解不同除草剂对玉米苗期田间杂草防控效果和玉米生产安全性的影响,以广西崇左主栽玉米品种正大719为试验材料,开展了田间不同除草剂防控效果和安全性研究。研究结果表明:不同除草剂喷施均对玉米田间杂草具有较好的防控效果,其中喷施烟嘧·莠去津和灭草松的效果最好,杂草防控效果达到90%以上;除灭草松喷施后表现出轻微药害外,其他类型的除草剂喷施后玉米均无药害发生;除草剂喷施后有助于玉米产量及其构成因素指标的提升。
Field grass damage is one of the main factors leading to the decline of maize yield and quality.In order to determine the influence of different herbicides on the control effect of weeds in maize seedling stage and the production safety of maize,Zhengda 719,the main maize variety grown in Chongzuo was used as experimental material to study the control effect and safety of different herbicides in the field.The results showed that different herbicides had better control effect on weeds in maize field,and the best control effect was applied on pyrimidine and atrazine,and the weed control effect reached more than 90%.There was no harm to maize after spraying with other types of herbicides except for the slight harm to the maize after spraying.Herbicide spraying was helpful to increase maize yield and its component factors.
