摘要
应用多效唑防御小麦倒伏试验的结果表明,在小麦苗期施用多效唑能够培育壮苗,起身期喷洒多效唑150～200ppm液30kg/亩,小麦基部节间缩短,茎壁增厚,防倒效果十分显著。在大田示范中,使小麦倒伏面积减少1/5～1/3;在未倒伏情况下,多效唑使小麦增产11.2％;在发生倒伏情况下,多效唑使小麦增产32.5％.同时发现多效唑对小麦锈病、白粉病和纹枯病有明显抑制效果。
The results of field test showed that the base node and stem outer covering of winter wheat was shortened and thickened respectively by praying 30 kg/mu (with 150-200ppm) of MET during erecting of witer wheat. The effects of preventing winter wheat from loding was signicent. In large area experiment, praying MET resulted in about 1/5-1/3 reduction loding areas. About yield of 11. 2 and 32. 5 percent of winter wheat was increased in the case of un-loding and loding respectively,and also,effects of restaining winter wheat yellow rust, powdery mildew and sheath and culm blight was showed abviously.
