谷子是我区主要粮食作物之一,约占粮田总面积的1/3,易形成草荒,防治甚难。草荒可造成50—80％的产量损失。谷田主要杂草为:马唐、狗尾草、虎尾草、藜、反技苋和刺儿菜等。为研究简便易行的除草方法,自1986年以来经多次盆栽、田间小区试验和生产示范等,从7种除草剂、14个不同剂量和混配中筛选出3种单剂和1种混剂可用于谷田除草。 Millet is one of the main food crops in our region, accounting for about 1/3 of the total area of ​​the grain crop, easy to form grassland, prevention and treatment is very difficult. Grass waste can cause 50-80% yield loss. Valley major weeds are: Crabgrass, Setaria, Chloris virgata, Chenopodium album, anti-Amaranthus and Calendula vegetables. In order to study the simple and convenient method of weeding, three kinds of single-herbicides and one kind of mixture were screened out from seven kinds of herbicides, 14 different dosages and compounding since 1986 after many pots, field plots and production demonstration. Agents can be used for field weeding.
