杉木是南方主要造林树种,进行撒播育苗时,除草工作十分艰难。目前在杉木圃地上采取化学除草,关键是找出杀草率高、药效期长、对苗木安全的除草剂。为此,我们从常用的几种除草剂及新品种中,筛选出了适合杉木圃地出苗前应用的除草剂-——氟乐灵。 Cunninghamia lanceolata is the main afforestation species in South China. When we carry out seedling nursery, weeding is very difficult. At present, we need to take chemical weeding on the fir-tree nurseries. The key point is to find the herbicide that has high killing rate and long-term efficacy and is safe for nursery stock. To this end, we have selected from several commonly used herbicides and new varieties, suitable for fir nursery application before emergence of the herbicide - trifluralin.
