直播、抛秧和移栽是目前水稻生产上常见的三种栽培方式,而且随着农业科研的深入和劳动力的重组,水稻栽培方式正在迅速地由传统方式向轻型栽培体系过渡。由于不同栽培方式之间稻苗秧龄的大小、扎根的深浅、苗床的质地和水肥管理等的差异,杂草的草相和危害往往是不同的。加之不同栽培方式对除草剂敏感程度的明显差异,使用中稍有不慎就会造成药害的发生,增加农本,浪费财力和物力。针对这种现状,我所杂草研究室从1991年起便对各种栽培方式水稻的杂草防除进行了全面的研究,本着高效、经济、安全、方便的原则,经过反复筛选,复配成功了适用于不同栽培方式水稻的三个除草剂品种,经大面积示范应用,深受农户欢迎,一次
Direct seeding, seedling throwing and transplanting are the three common cultivation methods in rice production at present. With the deepening of agricultural research and the reorganization of labor force, the rice cultivation mode is rapidly transiting from the traditional mode to the light-cultivation system. Due to the differences in the seedling age, the depth of roots, the texture of the seedbed and the management of water and fertilizer between different cultivation methods, the weeds and hazards of weeds are often different. Coupled with the different cultivation methods on the sensitivity of herbicides significant differences in the use of a little careless will result in the occurrence of injury and increase agricultural capital, a waste of financial and material resources. In response to this situation, weed research laboratory in 1991 weeding on a variety of cultivation methods of weed control conducted a comprehensive study of weeds in the efficient, economical, safe and convenient principles, after repeated screening, compounding Successfully applied to different cultivation methods of rice three herbicide varieties, demonstration and application of large areas, welcomed by farmers, once
