摘　　要：[目的]明确盐碱地高粱土壤处理除草剂的使用技术。[方法]通过单因素随机区组田间试验,测定9种土壤处理除草剂对杂草的防除效果及对高粱的安全性和产量的影响。[结果]38%莠去津SC、48%麦草畏AS、72%异丙甲草胺EC、40%异丙草·莠SC、38%莠去津SC+48%麦草畏AS在试验剂量下安全性好。38%莠去津SC 4500 mL/hm^2+96%精异丙甲草胺EC 825、1050 mL/hm^2和38%莠去津SC 3750 mL/hm^2+48%麦草畏AS 450 mL/hm^2(均为制剂用量)对杂草的综合防除效果好。38%莠去津SC+96%精异丙甲草胺EC、38%莠去津SC+48%麦草畏AS和40%异丙草·莠SC对高粱具有明显的增产作用。[结论]38%莠去津SC 4500 mL/hm^2+96%精异丙甲草胺EC 825 mL/hm^2和38%莠去津SC3750 mL/hm^2+48%麦草畏AS 450 mL/hm^2不仅对杂草防效好,而且对高粱安全,建议在生产上使用。[Aims] This study aims to comfirm the use technology of soil-applied herbicide in saline-alkali sorghum. [Methods] The single factor randomized block field was conducted to measure the effect of nine kinds of soil-applied herbicides for control of weed and the safety and yield of sorghum. [Results] Atrazine 38% SC, dicamba 48% AS, metolachlor 72% EC, metolachlor＂ atrazine 40% SC, atrazine 38% SC＋dicamba 48% AS were safe to sorghum at the test doses. Atrazine 38% SC 4500 ~＋S-mctolachlor 96% EC 825, 1050 mL/ha and atrazine 38% SC 3750 mL/ha＋ dicamba 48% AS 450 mL/ha showed a better control effect for weed control. Atrazine 38% SC＋S-metolachlor 96% EC, atrazine 38% SC＋dicamba 48% AS and metolachlor.atrazine 40% SC could increase the yield of sorghum obviously. [Conclusions] The control effect ofatrazine 38% SC 4500 mL/ha＋S-metolachlor 96% EC 825 mL/ha and atrazine 38% SC 3750 mL/ha＋dicamba 48% AS 450 mldha on weed and yield increase of sorghum were better than others, they axe recommended to use in the production.
