从土壤种子库角度探讨草坪杂草的可持续管理

土壤杂草种子库是草坪杂草发生危害的主要根源,种子库的动态变化规律对于杂草的综合管理具有非常重要的意义。本文对土壤杂草种子库进行了论述,同时提出在草坪建植与养护管理过程中实行基于杂草种子库调控的草坪杂草综合治理策略,即合理地运用物理的、化学的、生物的、生态学的手段和方法,有机的组合成“断源、截流、竭库”的杂草综合管理体系,将有害杂草有效的控制在生态经济阈值水平之下,实现草坪杂草的可持续管理。

A preliminary discussion on the turf-weed sustainable management from the soil weed seed bank

Soil weed seed bank is the primary source of future weed infestations and knowledge of seed bank dynamics is beneficial to integrated weed management. The soil weed seed bank were discussed. Carrying out the tuff-weed integrated management strategy, based on weed seed bank regulator, in tuff establishment and maintenance is presented. That is to say, physical, chemical, biological and ecological measures are rationally applied and organically combined into integrat- ed weed management system, which is cutting off the supply of weed seeds, intercepting seed dispersal, depleting the po- tential weed community. Then poisonous weeds are effectively controlled under ecological economic threshold level, and tuff-weed sustainable management is realized.
