摘要
池杉苗圃地的化学除草试验结果表明：克芜踪以剂量３０００ｍｌ／ｈｍ２的除草率最高，可达８０％（平均为６８．６２％），但除草不彻底。剂量为４５００～７５００ｍｌ／ｈｍ２的草甘膦，除草率可高达８５．５％（平均为７５．６１％～７５．７９％）。二甲四氯与克芜踪混施，最隹配方是３０００ｍｌ／ｈｍ２克芜踪＋１５００ｍｌ／ｈｍ２二甲四氯，除草率高的可达９０．８８％（平均８１．９４％）。结合除草效果与成本考虑，３种除草剂中以草甘膦除草率高、杂草死亡彻底、成本较低。
kinds of herbicides with different dose were tested in pond cypress ( Taxodium ascendens ) nursery.Paraquat of 3 000 ml/hm 2 , Glyphasate of 4 500～7 500 ml/hm 2 and their compound of 3 000 ml/hm 2 and 1 500 ml/hm 2 were used and each showed prominent effect. The average control rate reached 68.62%, 75.61%～75.79% and 81.94% respectively. Considering the effect and the cost, Glyphosate is the best.
