摘要
研究了激光精确除草的机理,并探索了激光切割杂草茎秆以及照射处于幼苗期的杂草顶端分生组织后对杂草的影响。实验表明,利用激光切割杂草的茎秆或直接照射杂草的分生组织上可有效地抑制杂草的再生长。利用激光进行除草,是一种潜在的控制作物内杂草的有效方法。
The objective of this paper explores the possibility of using CO2 laser for thermal and high - resolution weed control the close -to -crop area, and investigates the effect of laser treatment directed towards the apical meristems of selected weed species at the cotyledon stage. The experiment showed that the laser treatment of the apical meristems caused significant growth reduction and sometimes had lethal effects on weed species. Using laser for thermal weed control would be a good way to control the close -to -crop weed and reduce the pollution caused by chemical herbicides.
