摘要:
在陕西太白林业局苗圃进行了除草剂防除杂草试验,结果为24%林用惠尔乳油30、45、55、75、100 ml兑水45 kg,防除落叶松、云杉、油松、樟子松等针叶树播种育苗圃杂草,不会对种子出苗率产生显著影响,除草率58%~92%,随药剂浓度升高除草效果越好,药剂用量75 ml以上除草率才能达到85%以上; 24%林用惠尔乳油75 ml分别与5%精禾草克45、30 ml及15%精稳杀得25 ml组成混合药液(兑水45 kg),防治2 a生幼苗苗圃杂草,除草率都在85%以上,未对幼苗生长产生显著不利影响。建议生产中新建播种育苗苗圃喷施24%林用惠尔乳油100 ml兑水45 kg防除杂草,苗龄2 a及以上苗令苗圃应用24%林用惠尔乳油75 ml分别与5%精禾草克45、30 ml或15%精稳杀得25 ml混合用药(兑水45 kg)。
Abstract:
Herbicide experiment in nursery of Taibai Forestry Bureau was carried out.The result showed that 30 ml, 45 ml, 55 ml, 75 ml and 100 ml 24% of HERO were applied respectively, diluted with 45 kg water, for the control of weeds in nurseries for larix, spruce, Chinese pine and mongolian scotch pine.No significant impact was observed on germination of seeds and weed cleaning effect reached 58% to 92%.With the increase of herbicide concentration to 75 ml, the effect reached 85%.The mixture of 75 ml HERO 24% and 45 ml or 30 ml quizalofop-p-ethyl 5% and 25 ml onecide-p was diluted with 45 kg water and applied.The weed cleaning effect for 2 a seedlings in nursery reached over 85%, no impact on the seedling growing.So it is recommended that 100 ml HERO 24% can be diluted with 45 kg and applied to control the weeds at new nursery.For 2 a nurseries, mixture of HERO, quizalofop-p-ethyl and onecide-p, diluted with 45 kg water, was appropriate.
