杂草是庄稼的大敌。消灭农田杂草,保证粮食丰收,这是当前落实毛主席关于“备战、备荒、为人民”的伟大战略方针,是进一步夺取稳产高产的有效措施之一。在杂草的生活过程中,苗期的抵抗力较弱,对于除草剂的反应也较为敏感。所以一般来说,小草、嫩草较易防除。由于杂草多种多样,不同杂草对不同除草剂的抵抗力也不一样,这就要求我们在了解除草剂特性的同时,还要正确识别不同杂草的幼苗。为此,了解一些杂草幼苗鉴定方面的知识,对于我们正确识别不同植物的幼苗,是确保除草效果而不引起作物药害的必要前提之一。杂草幼苗的识别方法 Weeds are the enemy of crops. Eliminating farmland weeds and ensuring grain harvests is one of the effective measures to further seize steady and high output, which is currently implementing Chairman Mao’s great strategic guideline of “preparing for war, preparing for waste and for the people.” In the weed life, seedling resistance is weak, the response to the herbicide is also more sensitive. So in general, grass, tender grass easier to control. Due to the variety of weeds, different weeds have different resistance to different herbicides, which requires us to know the characteristics of herbicides and correctly identify the seedlings of different weeds. For this reason, understanding some of the weed seedling identification knowledge is one of the necessary preconditions for ensuring weed control effects without causing crop phytotoxicity when we correctly identify the seedlings of different plants.
