Lighter rates of nutrients 施用叶面肥元素施用率相对较低,用量少,肥料利用率高 Reduced chance of surge growth or fast release of nutrients from granular products- pending conditions 和颗粒肥相比,一般不会出现草坪草过密生长或者烧苗的 凊况-但也应考虑实际情况 Controlling growth of the plant 控制植物的生长 Only delivering nutrients when needed 只在需要供给植物养分时提供 Prepare turfgrass surfaces for important member events or tournaments 在有重要会员活动或赛事时,帮助更好的准备草坪以达到 要求的击打  Liquid Feeding -before or after major renovation work 在特殊养护前后施用液体肥  Liquid feeding- spring preparation 液体肥-为春季返青做准备  Consistency Control 效果均匀施用量控制  Balance between granular and liquid fertilizing 颗粒肥与液体肥交互施用  Plant ability to absorb nutrients 植物吸收养分的能力 Liquid and soluble nutrients that can be applied directly to the turfgrass leaves shoots and roots 易溶于水的产品可以直 接施用于草坪草的根茎 叶上  Plant ability to absorb nutrients 植物吸收养分的能力 Current formulations of liquid fertilizers are believed to penetrate mostly the transcuticular pores on foliage, which are open virtually all the time compared to stomata 目前液体肥所用配方成分被认为是能够穿透叶 片上的微细孔道-外质连丝被植物吸收,跟气孔 相比它张开的时间更长 More micro pores between stomas on cool season grasses 冷季型草坪草的气孔周边有更多微细孔道
