摘要
[目的]探讨芽前土壤处理除草剂采用药砂法防除玉米地杂草的使用技术。[方法]通过小区试验研究芽前土壤处理除草剂乙草胺采用药砂法防除玉米地杂草的效果。[结果]芽前乙草胺采用药砂法防除玉米地杂草,不仅具有同常规药液喷雾封闭法相同的防除效果,而且还具有工作效率高、使用成本低、对玉米安全、操作劳动强度低等特点,药砂法选用的干燥粗砂直径为0.2-0.3 mm,粗砂使用量以30 kg/hm^2为宜。[结论]该技术是适合农村留守老人操作的新技术。
[Objective] The aim was to explore the using technology of before buds soil-treated herbicides using by sand method against weeds in maize field. [Method] The control effect of Acetochlor using by sand method against weeds in maize field was studied through plot test.[Result]Acetochlor using by sand method not only had the same weed control effect with normal liquid spraying close method,but also had high work efficiency,low use cost and safety. The diameter of dry crude sand was 0. 2- 0. 3 mm,and dosage of crude sand was 30 kg / hm^2.[Conclusion]The technology was suitable for old people in villages to use.
