五氯酚钠防除稻田杂草的试验

摘  要：
在旱秧田、水秧田、旱直播田和水直播田的试验中,播前施用五氯酚钠,每公顷5—20公斤,除草效果不够良好。但在插秧本田的试验中,插前每公顷施用五氯酚钠15—30公厅对防除稗草(Echinochloa crusgalli (L.) Beauv.)和球穗莎草(Cyperus globosus All.)的效果极为良好。以在插秧前一天,每公顷施用30公斤效果最好,对稗草和球穗莎草的防除效果分别达到92.7%和79.6%。插后处理,每公顷施用五氯酚钠15公斤,效果也较好。另外的试验,观察了五氯酚钠不同剂型:颗粒剂、混土、溶液等的防除效果。防除稗草用颗粒剂和混土处理要优于溶液处理;防除球穗莎草则以溶液处理为最好。各处理对水稻均无药害,所有用五氧酚钠处理区的产量均高于不除草区,但较两次人工除草的为低。本文讨论了在秧田和直播田用五氯酚钠防除稗草效果较差的原因。

摘  要：
In the dry nursery bed,water nursery bed,dry planting field and water planting fieldtrials,pre-sowing applications of sodium PCP at 5 to 20 kg.per ha.did not give good controlof barnyardgrass(Echinochola crusgalli(L.)Beaur.).In the transplanting field trials,pre-transplanting treated with sodium PCP at the rates of15 to 30 kg.per ha.gave a control from good to excellent of barnyardgrass and Cyperusglobosus All..A rate of 30 kg.per ha.applied at one day before the seedlings were trans-planted was most effective,it gave 92.7% control of barnyardgrass and 79.6% control ofCyperus globosus All.Post-transplanting treated with sodium PCP at 15 kg.per ha.5 daysafter puddling also gave good control of both weeds.With different formulations of sodiumPCP tested(granular,soil-mixed and solution)post-transplant-applications of granular or soilmixed gave better control of barnyardgrass,but a solution was proved to be more effective forthe control of Cyperus globosus All.than the other two farmulations.No treatment caused rice injury.Yields of rice on all plots treated with sodium PCPwere higher than the unweeded plots,but were less than twice hand weeded plots.Unsatisfation for the control of barnyardgrass in the nursery beds and planting fieldswith sodium PCP was discussed.
