燕麦畏的挥发性较大,必须将药剂混入土内与土壤紧密结合才能很好地发挥药效。燕麦畏一般在作物播种前施用,并用圆盘耙或直齿耙纵横耙地以将药掺入土内。本试验研究了燕麦畏在相同混土深度下不同的药剂浓度及同一剂量不同混土深度对小麦和野燕麦之间的选择性,为田间正确施药提供依据。 Oatmeal is more volatile, must be mixed with soil agents and drugs in close cooperation with the soil to play a good effect. The oatmeal is generally applied prior to sowing of the crop, and is harrowed and harrowed by a disk harrow or a straight rake to incorporate the drug into the soil. This experiment studied the different concentrations of dandruff in the same soil depth and the different depth of soil mixed with the same dose of wheat and wild oats, and provided the basis for the correct application in the field.
