试验通过6%五氟.氰氟草悬浮剂单用、与56%2甲4氯钠可溶性粉剂混用、不同剂量组合等多种处理,研究各处理对直播水稻田杂草的防治效果与安全性。结果表明,6%五氟.氰氟草悬浮剂不同剂量对杂草防效影响较小;而与56%2甲4氯钠可溶性粉剂混用,提高了对杂草的防治效果,对阔叶杂草尤为明显。推荐药剂与667 m2剂量为在水稻4叶1心期后,6%五氟.氰氟草悬浮剂150～200 mL与56%2甲4氯钠可溶性粉剂25 g混用。试验药剂对水稻生长安全。
Experiments were conducted to study the control effect and safety of the treatments on weeds in direct seeding rice fields by using 6% pentafluoroacetonitrile suspension alone, mixed with 56% 2 sodium 4-chloro-soluble powder and different dosage combinations. . The results showed that 6% pentafluoroacetonitrile suspension had little effect on the control effect of weeds, but mixed with 56% 2 MCP-4 increased the control effect on weeds, Grass is especially noticeable. Recommended dosage of 667 m2 with a dosage of 6% pentafluoro-4-fluoropyridone suspension 150 ~ 200 mL and 56% 2-methyl-4-chloro-sodium soluble powder 25 g after 4 leaves 1 period of rice. Test agents on the growth of rice.
