| 摘 要： | 硬茬夏播田杂草种类达１５科，２７种。采用逐达和苗前除草剂混配播后苗前土壤处理，对已出苗和未出苗的杂草皆有很显著防盗，一次用药不仅可保证作物苗期免遭草害，而且对作物生育后期的杂草也可达到有效控制。所用除草剂均对玉米、大豆安全。由于有效减轻了草害，大豆平均增产１４．５％，玉米平均增产２１．２％。

| Abstract: | The techniques of weed chomical control were studied in com and soybean fields seeded on unfallowing wheat fields. Results showed that the preemergence treatments that included the mixed use of Roundup and preemergence herbicides had very significant control effects for weeds which amount to 15 families, 27 species. It not only restrains the emergence of mine weeds seeding, but also control effectlvely the weeds that emerge in later period of crop growing season. The yield increasing rate of soybean and corn were 14.5% and 21.2%. All treatments were safe to com and soybean. |
