摘要
随着水稻轻简化栽培技术的应用与推广,东北稻区、西北稻区、长江流域稻区和华南稻区等水稻主产区的杂草种群演替加快,稗草、千金子和马唐等恶性杂草频繁发生,杂草抗药性水平上升迅速。若杂草防控不及时、不彻底,极易对水稻生产构成严重威胁。为此,对水稻直播、机插和抛秧等轻简化栽培稻田杂草的草相特征、发展趋势和防除方法等进行了概述,以期为制定合理、高效的轻简化栽培稻田杂草综合防控技术、水稻用农药减量增效除草方案,延缓杂草抗药性产生与发展提供借鉴。
With the application and extension of simplified and labor-saving cultivation techniques for rice,the population succession of weeds accelerated in the main rice producing areas including Northeast,Northwest rice region and so on,the noxious weeds such as Echinochloa spp.,Leptochloa chinensis,and Digitaria sanguinalis occurred frequently,and the resistance levels were increased rapidly.The characteristics,development trends and control methods of weeds in paddy fields under simplified and labor-saving rice cultivation such as direct seeding,machine-transplanting,and seedling throwing were summarized in this review.The purpose was to provide the scientific references for the development of reasonable and efficient comprehensive control techniques against weeds,the plan of herbicide decrement and synergism,and for delaying the occurrence and development of weed resistance.
