我们在实验室条件下,研究了氟乐灵对于小麦、玉米种于抑制出苗的最低浓度及其对苗根的影响,氟乐灵是否随水渗淋从而与种子或根系接触造成药害,以及在小麦和玉米种子不接触氟乐灵的条件下,能否出苗生长等问题。并在此基础上进行了氟乐灵的田间试验,观察其在浅混土条件下的除草效果。 室内试验证明,氟乐灵抑制种子发芽生长的最低浓度,小麦为0.48ppm,玉米为4.8ppm,在常用量条件下,小麦、玉米种子直接与氟乐灵接触,其种子出苗、根的生长 Under laboratory conditions, we investigated the effect of trifluralin on the minimum concentration of wheat and maize to inhibit emergence and their effect on seedling root, whether trifluralin was infiltrated with water to cause phytotoxicity in contact with seeds or roots, and In the wheat and corn seeds do not touch trifluralin conditions, the emergence of growth and other issues. On the basis of this, a field trial of trifluralin was conducted to observe its weeding effect under the shallow mixed soil condition. Laboratory tests showed that trifluralin inhibited seed germination and growth of the minimum concentration of wheat is 0.48ppm, 4.8ppm of corn, under normal conditions, wheat, corn seed contact with trifluralin, the seed emergence, root growth
