本文对百菌清烟剂(烟柱、烟粉)点燃放烟后烟粒的分布、沉降动态进行了研究,明确了亩用300克10%百菌清烟柱每个放烟点有效扩散距离达15米以上,在温室大棚内每个放烟点有效防治面积为0.27～0.45亩,小棚有效防治面积为0.09～0.13亩。
In this paper, the distribution and sedimentation dynamics of the smoke granules after the CD89 smoke (smoke column and soot) were ignited were studied. It was found that the effective diffusion distance of each smoke point reached 300 mu M above the effective control area of 0.27 ~ 0.45 acres of each smoke point in the greenhouse, shed effective control area of 0.09 ~ 0.13 acres.
