摘要:

【目的】明确苗前封闭除草剂异丙甲草胺和二甲戊灵不同施用剂量对鹰嘴豆田杂草防效和鹰嘴豆苗的安全性。【方法】设置96 %异丙甲草胺EC 1 200 mL/hm2(C1)、1 500 mL/hm2(C2)、1 800 mL/hm2(C3)、3 000 mL/hm2(C4)、清水(CK1)处理,450 g/L二甲戊灵CS 1 500 mL/hm2(T1)、2 250 mL/hm2(T2)、3 000 mL/hm2(T3)、4 500 mL/hm2(T4)、清水(CK2)处理分别复配87.5 %2,4-滴异辛酯EC 600 mL/hm2,采用随机区组排列进行鹰嘴豆田杂草防效及鹰嘴豆生长安全性试验。【结果】96 %异丙甲草胺EC和450 g/L二甲戊灵CS分别复配87.5% 2,4-滴异辛酯EC可以有效地防除鹰嘴豆田单子叶杂草和双子叶杂草,C4处理的防效显著(P<0.05)高于其他处理;T4处理与T3处理相比,施药后45 d对单子叶杂草防效和总杂草防效差异不显著(P>0.05);T4处理施药后30 d对双子叶杂草防效和总杂草防效显著(P<0.05)高于其他处理。96 %异丙甲草胺EC和450 g/L二甲戊灵CS的不同施用剂量对鹰嘴豆苗均未发生药害。【结论】96 %异丙甲草胺EC 3 000 mL/hm2和450 g/L二甲戊灵CS 4 500 mL/hm2对单子叶杂草、双子叶杂草和总杂草防效较好;试验剂量内对鹰嘴豆生长安全。

Abstract:

【Objective】To clarify the weed control effect and the safety of varying application doses of pre-seedling blocking herbicides,metolachlor and pendimethalin on chickpea seedlings.【Methods】The weed control effect and the safety of chickpea growth in the field were evaluated using a random block design of 96% metolachlor EC 1 200 mL/hm2(C1),1 500 mL/hm2(C2),1 800 mL/hm2(C3),3 000 mL/hm2(C4)and clean water(CK1),or 450 g/L pendimethalin CS 1 500 mL/hm2(T1),2 250 mL/hm2(T2),3 000 mL/hm2(T3),4 500 mL/hm2(T4)and clean water(CK2)combined with 87.5% 2,4-D isooctyl ester EC 600 mL/hm2.【Results】96% metolachlor EC and 450 g/L pendimethalin CS combined with 87.5% 2,4-D isooctyl ester EC could effectively control monocotyledonous weeds and dicotyledonous weeds in chickpea field. The control effect of C4 treatment was significantly higher than that of other treatments(P<0.05). There was no significant difference in the control effect on monocotyledonous weeds and total weeds between T4 treatment and T3 treatment 45 days after application(P>0.05). The control effect of T4 treatment on dicotyledonous weeds and total weeds was significantly higher than that of other treatments 30 days after application(P<0.05). Different doses of 96% metolachlor EC and 450 g/L pendimethalin CS did not cause any damage to chickpea seedlings.【Conclusion】96% metolachlor EC 3 000 mL/hm2 and 450 g/L pendimethalin CS 4 500 mL/hm2 had better control effects on monocotyledonous weeds,dicotyledonous weeds,and total weeds. The test doses were safe for chickpea growth.
