氟乐灵(Trifluralin)已在黑龙江省大豆田广泛应用,对防除一年生禾本科杂草和某些阔叶杂草效果显著。该除草剂可在大豆播种前或大豆播种后出苗前施用。施于土壤表面后,为了防止药剂因挥发和光解损失,要求立即用圆盘耙或其它农具将药剂混入土中。混土深度因施药方法而异,播前施药混土宜深,一般在6～8厘米以内;播后苗前施药混土较浅,一般在3～4厘米。大豆萌芽出土过程中,要接触到药剂,在正常情况下对大豆生育影响较小。但在施药量过高,复土过深,或遇低温,大豆 Trifluralin has been widely used in soybean fields in Heilongjiang Province, and has significant effects on the control of annual gramineous weeds and some broadleaf weeds. The herbicide can be applied before sowing or before sowing after sowing. Apply to the soil surface, in order to prevent the agent due to volatilization and photolysis loss, requiring immediate use of disc harrows or other tools to pesticide mixed into the soil. Depth of soil mixing due to application methods vary, pre-sowing mixed application should be deep, usually 6 to 8 cm or less; sowing before spraying seedlings mixed shallow, usually 3 to 4 cm. Soybean sprout unearthed in the process, to come into contact with drugs, under normal circumstances have little effect on soybean growth. However, in the high dose, complex earth too deep, or in case of low temperature, soybeans
