稻象甲Echinocnemus squameus Billberg在80年代前,我地不成大害,不需用药防治。但80年代后,随着耕作制度的改革,免耕麦的扩种,改变了稻象甲的生态环境,数量不断上升,危害日益加重。尤以直播稻和小苗机插秧田受害为甚,严重田耕翻重栽。为此,自1988年以来,我们对稻象甲的测报技术作了如下研究。 Echinocnemus squameus Billberg As early as the 1980s, I was not a big deal, no medication control. However, with the reform of farming system after the 1980s, the expansion of no-till wheat has changed the ecological environment of the rice weevil. The quantity is constantly rising and the harm is aggravated. Especially in direct seeding rice and seedlings machine seedling damage is even worse, severe Tiangeng heavy plantation. To this end, since 1988, we have made the following study on the technology of rice meridians.
