摘要:【目的】为了早期：除一年生单子叶、双子叶杂草对春玉米生长发育的危害，明确试验药剂对一年生杂草的：除效果及其对春玉米的安全性。【方法】选用三元混配除草剂77%乙•莠•滴异辛酯悬乳剂和单剂900g/L乙草胺乳油、38%莠去津悬浮剂、87.5%2,4-滴异辛酯乳油对春玉米田进行土壤封闭处理：除杂草试验。【结果】77%乙•莠•滴异辛酯悬乳剂不同用量[1732.5、2310.0、2887.5、4620.0g(a.i)/hm2]处理可以有效地：除田间一年生杂草稗草、狗尾草、反枝觅和龙葵，施药后45d各处理总株：效均在96.9%以上，优于各单剂处理的：效，而且差异达到极显著水平(！<0.01)。
eels同时，三元混配除草剂各处理增产作用显著，与空白对照处理相比增产幅度达35.4%~50.8%。各药剂处理对春玉米生长无不良影响。【结论】利用该三元混配除草剂进行春玉米田土壤封闭处理，田间选择用药量1732.5~2310.0g(a.i)/hm2，可实现一次用药有效控制一年生单子叶、双子叶杂草、避免杂草与春玉米生长早期竞争水肥、节本增效的目的。

Abstract:[Objective]In order to prevent the harm of annual monocotyledon and dicotyledon weeds from the growth and development of spring maize in the early stage,the effects of the experimental agents on annual weeds and the safety of spring maize were determined.*Methods]The experiment
of controlling weeds in spring corn field by pre-emergence herbicide treatments was carried out with three compound herbicide77%acetochlor•atrazine•2,4-D-ethylhexyl SE and single herbicide900g/L Acetochlor,38%Atrazine and87.5%2,4-D-ethylhexyl SE.[Results]77%ethyl•atrazine•ethylhexyl SE of different dosage of[1732.5,2310.0,2887.5,4620.0g(a.i)/hm2]treatment can effectively control the annual weed field of green bristlegrass,amaranthus retroflexus,and nightshade.The total plant control effect of45d after various treatments applying pesticide was over96.9%,better than the control effect of each single agent,and the differences reached significant level(!<0.01).At the same time,the yield increa of ternary mixed herbicide treatment was significant, and the yield increa was35.4%-50.8%compared with the control treatment.There was no adver effect on the growth of spring maize.[Conclusion]The ternary herbicide mixture was ud for soil aling treatment in spring corn field,and the lected dosage of1732.5-2310.0g(a.i)/hm2in the field could effectively control the monocotyledons and dicotyledons of annual weeds,avoid the competition between weeds and spring corn in the early growth stage,and achieve the purpo of cost saving and efficiency enhancement.
