通过对青海云杉、祁连圆柏、樟子松、柽柳种源收集区进行杂草防除效果试验,结果表明,30%迪林飞达可溶性粉剂每667 m2用药量300～400 g,兑水60 kg,对防除青海云杉、祁连圆柏、樟子松种源收集区杂草效果都在85%以上;10%草甘膦水剂在防除青海云杉、祁连圆柏、樟子松种源收集区杂草效果也极显著,而且对青海云杉、祁连圆柏、樟子松无药害;3种除草剂对柽柳都产生药害,只是药害大小有很大差异。
通過對青海雲杉、祁連圓柏、樟子鬆、檉柳種源收集區進行雜草防除效果試驗,結果錶明,30%迪林飛達可溶性粉劑每667 m2用藥量300～400 g,兌水60 kg,對防除青海雲杉、祁連圓柏、樟子鬆種源收集區雜草效果都在85%以上;10%草甘膦水劑在防除青海雲杉、祁連圓柏、樟子鬆種源收集區雜草效果也極顯著,而且對青海雲杉、祁連圓柏、樟子鬆無藥害;3種除草劑對檉柳都產生藥害,隻是藥害大小有很大差異。

Through tests for weed control effect of provenance collection for Picea crassifolia,Sabina przewalskii,Pinus sylvestris var.mongolica,Tamarix chinensis,result shows that ： control effect for controlling weed in provenances collection areas of Picea crassifolia,Sabina przewalskii,Pinus sylvestris var.mongolica are more than 85% by using 30% Dilinfeida soluble powder dosage being 300-400 g/667 m2 dissolved in water 60 kg. Control effect of 10% glyphosate to control of weed for provenance collection for Picea crassifolia,Sabina przewalskii,Pinus sylvestris var.mongolica are very significant,but also have no phytotoxicity on Picea crassifolia,Sabina przewalskii,Pinus sylvestris var.mongolica;three kinds of herbicides have no phytotoxicity on Tamarix chinensis,just phytotoxicity size vary widely.
