目前国内化学除草发展很快,这已列入国家“七五”期间重点农业技术开发推广项目。近年舟山市的化学除草研究和使用面也有所发展,农户要求迫切,除草剂应用品种已有近10种。但由于化学除草有很强的选择性,加之农民对化学除草知识懂得不多,没能较好地掌握使用技术。使除草剂错用乱用现象时有发生,有的把除草剂当作杀虫剂、杀菌剂使用,造成农作物药害和死亡,导致严重减产甚至颗粒无收,特别是绿麦隆除草剂错用现象更为严重。1987年舟山市石礁乡一农民错在播种前将绿麦隆当除草醚使用,使秧苗长到2～3叶时,全部死光。补播的秧苗也有一半再次受药害死掉,类似这样的事
At present, the rapid development of domestic chemical weeding has been included in the key agricultural technology development and popularization projects during the “Seventh Five-Year Plan” period. In recent years, Zhoushan City, chemical weeding research and use of the surface has also been developed, farmers urgently require, there are nearly 10 species of herbicide applications. However, due to the strong selectivity of chemical weeding, coupled with farmer know little about chemical weeding knowledge, did not master the use of technology. So that the phenomenon of misuse of herbicides occasionally occur with some use of herbicides as insecticides, fungicides, resulting in crop injury and death, resulting in serious loss of yield or even crop failure, especially the use of erlenmertime herbicides misuse The phenomenon is more serious. In 1987, a farmer wrong Shihjiao Township, Zhoushan City, before the planting of chlorotoluron as weeding ether, the seedlings grow to 2 to 3 leaves, all dead. Half of the seedlings that make up are also killed by the drug again, something like this
